What is supervised learning?

Supervised learning, also known as supervised machine learning, is a subcategory of machine learning and artificial intelligence. It is defined by its use of labeled datasets to train algorithms that to classify data or predict outcomes accurately. As input data is fed into the model, it adjusts its weights until the model has been fitted appropriately, which occurs as part of the cross validation process. Supervised learning helps organizations solve for a variety of real-world problems at scale, such as classifying spam in a separate folder from your inbox. Supervised learning uses a training set to teach models to yield the desired output. This training dataset includes inputs and correct outputs, which allow the model to learn over time. The algorithm measures its accuracy through the loss function, adjusting until the error has been sufficiently minimized. Supervised learning can be separated into two types of problems when data mining—classification and regression: <ul><li>Classification uses an algorithm to accurately assign test data into specific categories. It recognizes specific entities within the dataset and attempts to draw some conclusions on how those entities should be labeled or defined. Common classification algorithms are linear classifiers, support vector machines (SVM), decision trees, k-nearest neighbor, and random forest, which are described in more detail below.</li></ul> <ul><li>Regression is used to understand the relationship between dependent and independent variables. It is commonly used to make projections, such as for sales revenue for a given business. Linear regression, logistical regression, and polynomial regression are popular regression algorithms.</li></ul> <h4>Supervised learning algorithms</h4> Various algorithms and computations techniques are used in supervised machine learning processes. Below are brief explanations of some of the most commonly used learning methods, typically calculated through use of programs like R or Python: <ul><li>Neural networks: Primarily leveraged for deep learning algorithms, neural networks process training data by mimicking the interconnectivity of the human brain through layers of nodes. Each node is made up of inputs, weights, a bias (or threshold), and an output. If that output value exceeds a given threshold, it “fires” or activates the node, passing data to the next layer in the network. Neural networks learn this mapping function through supervised learning, adjusting based on the loss function through the process of gradient descent. When the cost function is at or near zero, we can be confident in the model’s accuracy to yield the correct answer.</li></ul> <ul><li>Naive bayes: Naive Bayes is classification approach that adopts the principle of class conditional independence from the Bayes Theorem. This means that the presence of one feature does not impact the presence of another in the probability of a given outcome, and each predictor has an equal effect on that result. There are three types of Naïve Bayes classifiers: Multinomial Naïve Bayes, Bernoulli Naïve Bayes, and Gaussian Naïve Bayes. This technique is primarily used in text classification, spam identification, and recommendation systems.</li></ul> <ul><li>Linear regression: Linear regression is used to identify the relationship between a dependent variable and one or more independent variables and is typically leveraged to make predictions about future outcomes. When there is only one independent variable and one dependent variable, it is known as simple linear regression. As the number of independent variables increases, it is referred to as multiple linear regression. For each type of linear regression, it seeks to plot a line of best fit, which is calculated through the method of least squares. However, unlike other regression models, this line is straight when plotted on a graph.</li></ul> <ul><li>Logistic regression: While linear regression is leveraged when dependent variables are continuous, logistic regression is selected when the dependent variable is categorical, meaning they have binary outputs, such as "true" and "false" or "yes" and "no." While both regression models seek to understand relationships between data inputs, logistic regression is mainly used to solve binary classification problems, such as spam identification.</li></ul> <ul><li>Support vector machines (SVM): A support vector machine is a popular supervised learning model developed by Vladimir Vapnik, used for both data classification and regression. That said, it is typically leveraged for classification problems, constructing a hyperplane where the distance between two classes of data points is at its maximum. This hyperplane is known as the decision boundary, separating the classes of data points (e.g., oranges vs. apples) on either side of the plane.</li></ul> <ul><li>K-nearest neighbor: K-nearest neighbor, also known as the KNN algorithm, is a non-parametric algorithm that classifies data points based on their proximity and association to other available data. This algorithm assumes that similar data points can be found near each other. As a result, it seeks to calculate the distance between data points, usually through Euclidean distance, and then it assigns a category based on the most frequent category or average. Its ease of use and low calculation time make it a preferred algorithm by data scientists, but as the test dataset grows, the processing time lengthens, making it less appealing for classification tasks. KNN is typically used for recommendation engines and image recognition.</li></ul> <ul><li>Random forest: Random forest is another flexible supervised machine learning algorithm used for both classification and regression purposes. The "forest" references a collection of uncorrelated decision trees, which are then merged together to reduce variance and create more accurate data predictions.</li></ul>

AUTOMATION SDET

Robotic Process Automation in Healthcare Industry

Robotic Process Automation (a.k.a. RPA) now has the potential to be a complete human process simulation and not just repetitive task automation. Very recent breakthroughs enable RPA to be usable in complex healthcare information technology environments and is a direct interface to AI (Artificial Intelligence) driven business solutions. Nowadays&nbsp;health leaders&nbsp;and healthcare industry CFOs indicate overall&nbsp;cost reduction and improve efficiency as one of their top two financial priorities.&nbsp;The operations team from the health care system use Robotic Process Automation to transform a completely manual process into an automated process to cut costs and improve efficiency. There are numerous automation tools and techniques but Robotic Process Automation (RPA) is&nbsp;one of the best options for the implementation of process automation in the healthcare systems since RPA has the potential for great transformation. Initially, healthcare systems started using RPA for back-office processes in order to eliminate paperwork and reduce the amount of time it takes to process files but now RPA is going far beyond these simple tasks and helping healthcare providers not only reducing costs and gaining efficiency, but also increasing the quality of patient care and the amount of time spending with patients. As patient numbers increase, health service providers are tested with overseeing levels of stock, supporting digitization of patient records, maximizing appointment, and executing billing and claims processing. To help conquer these operational pain points, increasingly more healthcare industries are grasping RPA to mitigate these difficulties and drive improved effectiveness and development. According to&nbsp;UiPath&nbsp;“Healthcare industries are predicted to have a 36% automation potential”. This implies in excess of 33% of healthcare assignments— particularly administrative, back-office capacities—could be automated, allowing healthcare providers to improve the customer experience because automating classification saves time and money, prevents misdirection and reduces human error. <h4>Healthcare’s major pain points before automation:</h4> There are many pain points&nbsp;faced in becoming more streamlined and efficient as a whole. Some of the biggest pain points faced by healthcare providers include: <ol><li>Rising healthcare costs</li><li>Changing healthcare demographics</li><li>Lack of efficiency and customer experience</li><li>Billing &amp; claims management</li><li>Inventory management</li><li>Patients appointment and entering their records manually</li></ol> Before automation, security was the main concern for the healthcare industry but now it’s not the case since robots are looking at our data, not humans looking at our data.Largest number of hospitals having more than 2000 beds were doing lots of activities manually, accuracy and frequency was a challenge, people were not able to complete activities on time. Once health leaders introduced with RPA since then not looking back.Healthcare wants to start small but to scale up as and when required and RPA is helping healthcare to automate tasks. Earlier, there was a huge volume of email from insurance providers that used to be fed into the system and the entire activity was manual and there was a high chance of missing data entry in many cases. RPA came into healthcare’s rescue where it read all email successfully and entered into the system, saving time and boosting accuracy. The kind of benefit that an operations team is getting from putting RPA is that they have been able to do things which was not humanly possible to do.So much data that they deal with there in the system , every patient may have probably thousand, five hundred interactions or episodes within a stay. RPA is now able to give them data which they could work upon so it’s improved their productivity and now they can really make a difference to the business and it has also given a lot of control. Earlier, they were dependent on human beings so there can be some mismatches and somebody tries to reconcile data manually but RPA really throws up the accurate matching or reconciliation of the data and also the speed is really immense. Now we can get the business reports every day. By the time they reach office, they know what’s happened and where the problem lies.With the success with RPA so far, they now plan to scale up RPA in other areas such as reading and processing bank statements. They are also automating the invoicing process.<h4> </h4><h4>Use cases of RPA in healthcare:</h4> As hospitals work to cut costs, increase efficiency, and drive high quality care for patients, there are many roles that RPA plays in achieving these goals. Some of them include:&nbsp; <ul><li>Improve healthcare revenue cycle management:&nbsp;The use of RPA in the healthcare industry has great potential to expand far past back office functions. In particular, RPA can greatly help within the revenue cycle management and accurate eligibility confirmation helps streamline claims submission to and reimbursements from health plans. RPA is capable of improving billing efficiency. Additionally, RPA is also highly beneficial in healthcare records to provide analysis and data based on a patient’s condition and response. The use of RPA in the healthcare field is extensively advantageous to the financial performance of medicinal services.</li></ul> <ul><li>Account settlements:&nbsp;Medicinal services manage various patients’ records one after another. This may incorporate tests, medicines, specialists’ expenses, and different offices. Manually calculating them and dealing with these records may bring about blunders. RPA tools can help healthcare companies in ascertaining a patient’s bill by taking information from various divisions and sending a notice to the patient. Robotizing account settlement with RPA decreases installment postponements and errors in calculating the bill sum.</li></ul> <ul><li>Claim Management:&nbsp;Medical coverage guarantees the executives incorporates a few procedures. Gathering insurer’s information, assessing, and preparing it is time taking the procedure and mistake inclined also. Robotizing protection guarantees the executives utilizing RPA guarantees that all compliances are met while handling the case and is done quicker than people do. Also, robotization here ascertains that unpredictable protection claims took care of with proficiency.</li></ul> <ul><li>Patient and health plan management :&nbsp;Automation makes population health management feasible, scalable and sustainable.</li></ul> <ul><li>Better cost management:&nbsp;A product robot’s cost is commonly one-fifth the expense of a full-time human services staff part. RPA can convey up to 47% generally speaking reserve funds, particularly in healthcare payer BPO. With RPA insightful planning and multi-tenure, healthcare providers can use a financially savvy workforce and fundamentally diminish working expenses. Robots can be sent in cloud or on-premises from a single central server, making automation possible across multiple independent business units.</li></ul> To that stand RPA, specially UiPath becomes very important for the healthcare industry to move ahead on the IT (Information Technology) and automation technologies.RPA is recommended to small healthcare companies, who are looking to start automation journeys in healthcare’s day to day activities.

RPA in Healthcare Industry: Transforming Processes & Efficiency

ROBOTICS PROCESS AUTOMATION

Robotic Process Automation Simplified

RPA –&nbsp;Robotic&nbsp;Process&nbsp;Automation&nbsp;is a form of business process automation technology based on metaphorical software robots (bots).Whoa! Sounds like a sci-fi movie, doesn’t it? But don’t worry it is not and if you have a knack for it you could create a rewarding career out of it!

<h3>Don’t have the ‘knack’? Don’t worry you can learn it!</h3> So,&nbsp;Robotic&nbsp;Process&nbsp;Automation is one of the coolest and revolutionary things to hit the technology and business industry easing the work of the people and redirecting human talent to areas that provide more return. It frees up the resources to focus on tasks that require creativity, decision-making and judgment. It automates the task just like a human being was doing it across platforms and systems.Any company that uses labor on a large scale for general knowledge process work, where people are performing high-volume, highly transactional process functions, RPA will boost their capabilities and save money and time with robotic process automation software. Such as the Banking sector, this sector is known for its lengthy processes around information input and exchange but not anymore as RPA is introduced into the equation it is becoming a much smoother and shorter ride.&nbsp;<a href="https://www.channelnewsasia.com/news/singapore/robots-banks-singapore-uob-ocbc-9433032" rel="noopener noreferrer" target="_blank">United Overseas Bank (UOB)</a>&nbsp;for instance was able to considerably reduce the time taken to process requests for letters of credit from the corporate clients. Just like industrial “robots” or machines reshaped the manufacturing industry by creating and developing higher quality products in half the time RPA “robots” are remodeling administration, business, IT support processes, remote infrastructure and other back-office and virtual office work.You know how cool it is to watch “How stuff works” in any given manufacturing industry such as making cheesecakes on a large scale or the speed packaging of beauty products. RPA is like that only on virtual plane instead of physical. One of the major improvements it provides is the increased accuracy lowering the human error and increased productivity while removing people from dull, repetitive tasks to more rewarding ones!

<h3>Why RPA?</h3> So when we think about RPA we think its main goal is simple – to replace the repetitive and boring clerical and often low-value tasks performed by humans with a virtual workforce. But is that it? We fail to realize what this ‘simple’ goal can achieve for us.Consider this – the business, technology and every other industry now being linked with technology is rapidly evolving, sometimes at such a pace that it is hard for us to keep up with it. With the changing business processes imagine how much human workforce would be in need of frequent updates if we try to keep up with these changes. Increased workshops and meetings every couple of days discussing the new changes, hiring individuals who have the ability to fill this gap and so on. This lengthy approach to tackle small and frequent changes clearly highlights one thing –&nbsp;Waste of time and resources

<h3>Solution? RPA!</h3> With any change in the business process be it tiny or colossal, a company would only need to make a few changes in the software code which is always cheaper and faster. So weeks of work is reduced to a mere few minutes! But the real question is,

<h3>Do the ever-changing business sectors find value in this asset? and Is there a future in RPA?</h3> Yes! And Yes! According to a report at&nbsp;<a href="https://www.grandviewresearch.com/industry-analysis/robotic-process-automation-rpa-market" rel="noopener noreferrer" target="_blank">Grand View Research</a>, the global robotic process automation market size was valued at USD 1.1 billion in 2019! Increasing demand for business process automation (BPA) through the use of Artificial Intelligence (AI) and software bots is anticipated to be the key growth driver. The businesses across the globe are transforming into a dynamic digital environment. And by 2027 the RPA market is expected to reach USD 10.7 billion! Read the report&nbsp;<a href="https://www.grandviewresearch.com/press-release/global-robotic-process-automation-rpa-market" rel="noopener noreferrer" target="_blank">here</a>. Do something today you will be proud of tomorrow Knowing how the market works and where it will flow gives you the opportunity to invest your time and skills in the right thing which ensures return and increases value. We don’t even realize that currently RPA does play a role in our lives. In banking, shopping and even basic customer feedback, bots are already a crucial part of our experience. In the near future we can expect the following, <ul><li>RPA will be widely used in different domains and industries like BFSI, Manufacturing, Retail, Analytics, Aviation, Oil and Gas and even Legal!</li><li>Data entry and Data rekeying jobs will be managed with automated tools and techniques</li><li>All computer aided processes that can be governed by a set of protocols will be managed with the help of RPA and most of them already are</li><li>RPA can even be used for formatting tasks given a set of rules</li></ul> In the near future almost every industry would require the input of Robotic Process Automation, this change is inevitable as we move into the realization that we need to redirect the time and resources we are spending on mundane tasks towards our growth and value. It is anticipated an abundance of jobs in the following industries and most of them do have some level of input of RPA. <ol><li>Banking</li></ol> This one is obvious as right now the most in need of this powerful asset. With a massive number of account documents, templates, deposits, withdrawals and other transactional files the most effective management can be achieved through RPA 2.	InsuranceInsurance is one of the industries with a lot of back office work easily divided into a number of sections –&nbsp;be it car, health, travel, real estate. Insurance agencies are now turning over to bots to help them streamline their business processes and increase their ability to take on more clients 3.	TelecommunicationsThe current bot experience in telecommunications requires a dire need of improvement and the companies are working to make this happen 4. UtilitiesGas, electric, water etc. – deal with monetary transactions every day, so an opportunity for the RPA would be in accounts and billing and further expanding this into meter-reading, handling customer service queries or debt recovery. 5. ManufacturingThe manufacturing industries are swiftly moving towards linking their mechanical machines with computer-aided software processes so with just a few simple commands large man-power can be managed single-handedly! To sum up, this skill is proving to be a powerful asset and it is the demand of today and tomorrow. Being skilled in RPA also provides you with the opportunity to explore all industries with smooth transitions. So if you are thinking about going into RPA then I say go for it! The demand is high.

MICROSERVICES

What is Microservices Architecture?

If a software developer is working on a project, then s/he is essentially working on an application. The scope of this application can vary depending upon the business requirements. It can be as simple as publishing the current time on screen too as complex as managing an e-commerce website. The basic idea behind microservices architecture is to break down a complex requirement into a set of simpler requirements with each of it implementing a distinct functionality. So, these sets of simpler functionalities when grouped together will serve the purpose of fulfilling one single complex requirement.

Any server-side application, irrespective of its complexity, follows layered architecture which consists of various components – UI Layer, Business Logic, Database Access Layer, Integration Layer. Despite its modular structure, these applications were packaged together and deployed as a single unit i.e. deployed as a monolith. But over time software development kept on evolving. Though monolithic architecture carries its own set of benefits viz. simple to develop, simple to test, simple to deploy, its drawbacks started to frustrate the software engineering community. Let’s look at some of its major disadvantages: <ul><li>As monolithic application starts to grow, the code base becomes complex to understand and hence maintainability becomes an issue.</li><li>Scaling gets challenging.</li><li>Continuous build, integration and deployment process starts consuming more time and resources.</li><li>It becomes difficult for a new team member to kick start his/her development.</li><li>It becomes extremely difficult to migrate the application to newer technology or even introducing different technology in any of its modules becomes fairly challenging. Because with time, everything gets tightly coupled.</li><li>Bug in one module, brings the whole application down.</li></ul>

The disadvantages of monolithic applications gave rise to microservices architecture. As mentioned earlier, the idea behind this architecture pattern is to split one large application into a set of smaller, interconnected services. Each microservice is in itself a small application which is deployed independently and has its own layered architecture consisting of business logic along with various adapters. Some would expose a REST or message-based API and others would consume APIs provided by other services. In fact, if you want to benefit from microservices, then each microservice should have its own database. Though it would disturb the idea of having one database per enterprise model, it ensures loose coupling. Moreover, service is free to use a type of database that is best suited to its needs.

<ul><li>It reduces complexity of a large application as now one must develop and maintain set of small services independently.</li><li>Scaling your application becomes easy.</li><li>Enables the continuous delivery and deployment of large, complex applications.</li><li>Speeds up the whole development process as now developer can concentrate on his/her specific requirement and kick start the development.</li><li>It eliminates the use of a single technology stack for the long term. When developing a new service you can pick any new technology stack.</li><li>Bug in one module affects just the one microservice. The other services will continue to handle requests.</li></ul>

Microservices architecture has its own set of complexities. <ul><li>As microservices architecture is a distributed system, it has all the disadvantages of it.</li></ul><ol><li class="ql-indent-1">Network reliability becomes an issue. One should choose and implement an inter-process communication mechanism based on either RPC or messaging and write code to handle partial failures.</li><li class="ql-indent-1">A security mechanism should be tight and should be implemented from the beginning.</li><li class="ql-indent-1">There are costs associated with maintaining distributed networks.</li></ol> <ul><li>Managing distributed transactions becomes difficult if your architecture is following one-database-per-microservice architecture pattern.</li><li>Developers have to deal with additional complexities while developing microservices.</li></ul><ol><li class="ql-indent-1">Testing becomes difficult as the developer needs to launch that service and all other services that it depends upon.</li><li class="ql-indent-1">Implementing use cases that impacts multiple services requires careful coordination among team members.</li></ol> <ul><li>Deployment complexities.</li></ul><ol><li class="ql-indent-1">A microservice application typically consists of a large number of services. Each service will have multiple runtime instances. And each instance needs to be configured, deployed, scaled and monitored.</li></ol>

Building complex applications is inherently difficult. Monolithic architecture better suits simple, lightweight applications whereas microservices architecture pattern is the better choice for complex, evolving applications. Let’s suppose you are doing a POC on some requirement, and you need to deliver it fast. You have zero ideas about whether your work will bring value. The purpose of this POC is just to check whether you’ll be able to proceed further and start implementing your real product or not. You’re not building it for scale. You’re probably going to be running multiple tests and redeploy your application many times. For this, monolithic architecture must be your go-to approach because changing things quickly can be done all in a single place. Opting for microservices architecture would distract you from your primary objective as it comes with its own set of complexities. Now when your POC is turned out to be a success, you will start your real product implementation. This involves creating a product team with the manager, developers, testers, business analysts along with a product owner. Now, when your team size is small, and you are focused on quick implementation and you’re still figuring out the right boundaries of business and technical features, then again monolithic approach is what you should opt for. But once your product is kicked off, your team size starts growing and you find the need of scaling it further, then you’re probably at the point to optimize for microservices.Similar is the case with any flagship/legacy application. If this application has been asking for enhancements frequently and you’re struggling with its existing complexities, then, in this case, microservices can come to your rescue. The microservices approach is all about handling a complex system, but in order to do so, the approach introduces its own set of complexities and implementation challenges. So, if you’re confident enough to manage your system’s complexities with a monolithic architecture, which requires a lot of discipline and coordination within the team, then stick to it. Otherwise, if modularity and decentralization are your primary objective and you’re committed to use cutting edge technologies then microservices architecture is your thing.

What is Automation?

IT industry has gone through a major revolution within last decade. The project execution model has changed a lot. Waterfall Model – In this model – there were almost constant requirements and was like a fixed bid project to be delivered at agreed upon timelines. IT managers used to plan around people, process and technologies and communicated to customers. Typically in this model – there were six major phases in this cycle: Requirement Gathering -&gt; Design -&gt; Coding &amp; Unit Testing -&gt; System &amp; Integration Testing -&gt; Production Deployment -&gt; Post Production Support Agile Model – Waterfall model had its own advantages but it had major drawback. Requirements used to get reviewed and finalized at the beginning of software development lifecycle – so it turned out to be cat when dog was expected. It led to client dissatisfaction. Agile solved this problem by introducing shorter release cycles in form of program increments and sprints. It had requirement gathering, design, coding &amp; unit testing and system testing in each sprint. Sprint demo to customer also solved the dog turning cat in the end. However, Integation and Production deployment in the end led to many conflicts between development &amp; Operations team and also issues in production release. Automation involves a very&nbsp;broad range of technologies&nbsp;including robotics and expert systems, telemetry and communications, electro-optics, Cyber security, process measurement and control, sensors, wireless applications, systems integration, test measurement, and many, many more.

At the current rate of growth, as per top industry prediction, nearly each and every industry will be using RPA to some extent&nbsp;by 2023. The emerging RPA technology is widely adopted in various industries such as BFSI, retail, healthcare, and IT &amp; telecom, banking &amp; financial services, Human Resources, manufacturing, insurance, energies and utilities, and among others.

This article will help you to understand what kind of underlying applications you’ve for your projects and based on that you can choose the particular type of RPA tools. If you are the process owner or if you are a part of any RPA team then if you are in a confusion to&nbsp;know which tool to select or which tool to select for my particular process or now what is the way so that I can choose as you know there are so many RPA tools in the market so how do we know which particular tools have to select for my particular process so we’ll explain you to choose best tool for your business requirements. After going through this article, you will be well-positioned to make right and quick decisions to&nbsp;select RPA tools. There are so many automation tools in the market, but here are the top 5 RPA tools available in the current market, as per Google: <ul><li>Automation Anywhere</li><li>UiPath</li><li>Blue Prism</li><li>Pega</li></ul>

<ul><li>Underlying Application: Need to understand the target and underlying applications of the processes to be automated</li></ul> <ul><li>Ease of deployment: How easily the RPA tool interacts with application at the presentation layer and how the BOTs can be deployed at different environments</li></ul> <ul><li>Control and Monitoring: Need to understand- Real time control, Advanced scheduling &amp; API, Alert and exceptions, real time status monitoring and tracking the logs</li></ul> <ul><li>Scalability: Need to understand- how quickly and easily the solution responds to business requirements, changes, exceptions, or increasing operations</li></ul> <ul><li>Resource/Pricing Model:&nbsp;Identifying the correct resources and pricing model</li></ul> It is very important for you to understand these factors or these parameters&nbsp;before you’re choosing the RPA tools. You should understand the type of the applications that are correct and involved in your particular project will have to understand the target target and order by applications of the processes to be automated and the second is deployment. The three main RPA tools currently in the market are Automation Anywhere, UiPath and Blue Prism. So here we have compared them on the&nbsp;different features and support, so that you are enabled to decide which is the best fit as per your business requirements such as development environment support, production environment support, version control system, Security/Data control, NLP ML etc.

Process Automation and Mitigating Risks during Natural Disasters

<h3>How can Process Automation help in mitigating risks during Natural Disasters?</h3> The combined year of 2019-2020 has hit the world hard.&nbsp;The world lost as much as $232 billion due to natural disasters alone in 2019, with India leading in casualties with 1,750 deaths, said a recent report by AON. Unfortunately there might be more to come and we must be prepared. Process Automation if explored and used in depth has wonders hidden under its seemingly simple appearance. From optimizing mundane tasks to even taking care of complex processes. Process Automation is revolutionizing the market! But imagine its use if we use it with something where the power of the human abilities is severely limited and often logic cannot predict the next thing and the damage goes beyond its extensive degree. That’s correct&nbsp;Natural Disasters! No matter how advanced the human civilization evolves to be, we cannot prevent the occurrence of the Natural Disasters although we are the reason for them! But that is a discussion for another day. Currently with the advancement of science our researchers and scientists can almost successfully predict most natural disasters before they appear and with our abilities we try to control the damage as much as possible. The loss of invaluable human life, crashing down of properties and infrastructures, loss of food and other resources are only some of the damages listed. But with the addition of Process Automation the prediction, immediate response criteria and damage control can reach new levels of efficiency saving lives and the prevent the need to build everything from scratch again. In the present, thanks to our researchers and scientists there are tools and systems especially designed which can almost accurately predict these phenomenon of nature and gives us a heads up. 1. Earthquake There is&nbsp;seismic data&nbsp;and the observance of seismic activity to analyze the&nbsp;magnitude&nbsp;and&nbsp;patterns&nbsp;of earthquakes which can predict the location and time of the earthquake 2. Flood Amount of rainfall received based on&nbsp;real time data, the rate of change of river flow which indicate severity and immediacy of threat and many more such data recording helps in flood forecasting. 3. Volcanic Eruptions A&nbsp;volcano&nbsp;that is about to&nbsp;erupt&nbsp;may produce a sequence of earthquakes. Scientists use seismographs that record the length and strength of each earthquake to try to determine if an&nbsp;eruption&nbsp;is imminent 4. Cyclones (and even hurricanes and typhoons) Meteorologists around the world use modern technology such as satellites, weather radars and computers etc. to track tropical&nbsp;cyclones&nbsp;as they develop. These are only some of the natural disasters we combat but now we must connect the invisible thread that forms the basis of the current and the future structure of the industries across the globe – Process Automation Almost all the real time data recorded and the systems used for the predictions and calculations can be hitched to a carefully designed system of Process Automation, where the bots can successfully and accurately predict the occurrence, location and the level of the natural disaster. The bots after being alerted of this will initiate a response sequence which would help in the prevention of damage by deploying the required help by evacuating areas, saving resources and preparing for medical and other operations.

<h3>Disaster Recovery</h3> The advantages of Process Automation are not limited to the pre-disaster phase. It extends beyond to the recovery phase. The degree of loss is not limited to the physical infrastructure when a building is hit by a natural disaster such as earthquake, tornado or flood. Any paper-based working system would likely be lost, but even businesses that have made the switch to paperless would have problems. How long would it to take rebuild to what it is today? However Process Automation saves all this tiring and often traumatic procedures by simply doing what it’s designed to do. After being alerted of the upcoming calamity bots can commence their work to back up data, sending them to different servers where they can be easily accessible from different devices and location. If work areas are inaccessible in the days and weeks following the disaster, employees can still access them from any device that has an internet connection, whether they’re working from home or in a temporary work setup. We are already using the latter in the challenging times of the Covid-19But most importantly, they can instigate the application of insurance operations by sending the essential documents and a detailed report of the occurred catastrophe of which the humans are often incapable of mentally and physically till they find their ground again. Moreover, the bots will be aware of the disaster-hit locations and can send and receive responses from the people stuck there. They can also collect significant data of the losses that arise. All of this extensive work and recovery can be done with a carefully designed system of Process Automation where algorithm if of the utmost importance and taking into account real time data and responses. If explored with the right mind frame and the right intention it would be a breakthrough for the human race saving countless lives and billions of dollars every year. Further we would be able to study our planet and its behavior and changes in depth and more precisely. This would compel us to take the right actions to make our home a better place.
