The deep knowledge in GPU and CUDA along with hands-on practice helps the candidate to get a job easily in big firms for working as data scientists.

  1. In-depth understanding of algorithms

Numerous algorithms such as logical regression, linear regression, decision trees, SVM algorithms, Naïve Bayes, KNN algorithm, K-means algorithm, and random forest algorithm, dimensionality reduction algorithms, and gradient boosting algorithm and AdaBoosting algorithm are popularly utilized in data science process and implemented in various projects. 71% of data scientists are implementing these algorithms for performing various scientific computations and numerical calculations.

  1. An acquaintance in Cloud Service Providers

Big companies are adapting to cloud practice from on-premise solutions for easy access, cost-effectiveness, and data security. A situation like Pandemic makes employees work from home and it relies on Cloud Computing for providing uninterrupted solutions to users. The knowledge in Cloud Service providers is the need of the hour and nearly 70% of companies using AWS, 20% of companies using Azure and many companies are using other small providers as per their investments.

  1. Proficiency in Visualization tools

Data Visualization is the main part of the data science process as it displays the data in an understandable format to clients as well as industry leaders. There are some frequently used tools in the market such as Tableau, PowerBI, and MSBI, and so on. The learning of visualization tools helps the candidate to perform a data visualization process that becomes useful for decision-making purposes.

  1. Knowledge of Github usage

Data Scientists are utilizing this Github Platform to collaborate and contribute their projects for the benefit of beginners and enterprise project managers. There is a wide range of projects available in Github and many of them are available as open-source. Finding a suitable project that can be useful for developing projects is helpful for the data scientist to fasten the development and deployment.

  1. Well-versed with available IDEs

IDE (Integrated Development Environment) is used to write, debug, and implement codes, and sometimes data scientists require to develop a code or some for their projects. These IDEs are used to complete the debugging process, resource management, and another related process. Notebook, PyCharm, and RStudio are widely used by data scientists around the world and the knowledge of them is useful for beginners to perform the same.

  1. Hadoop Expertise

Big Data Analytics is the recent trend as the world generates trillions of data every day through applications and website usage. These large amounts of data to be structured for the decision-making process and it offer a cost-effective solution by using the tools like Hadoop. Therewith, the expertise in Hadoop is considered a must-have skill, and learning them will be helpful for the students to sustain strongly in data science platform.

End Note

Demand for data scientists and data analysts are growing every day and you can check them in job portals. All the job descriptions contain the above skills and gaining expertise in these areas helps attain the job easily in big companies. The certification along with hands-on exposure is required in all areas and top institutes in Chennai provide them to bridge the knowledge gap of global industries.

RPA (Robotic Process Automation) is an automated rule-based business processes to do efficient execution of deploying robots with cost-effective development. RPA reduces the human involvement in the process of automating workflow with the help of robots or software applications. There are three main terms you as a beginner need to understand:  Robotic, Process, and Automation.

Robotic: Entities that are mimic human actions.

Process: Systematic process steps for executing a meaningful activity.

Automation: Automatic action that is done by a robot without any human intervention.

These three terms together make mimicking the human actions by performing the sequence of steps and brings an effective activity without human interaction is known as Robotic Process Automation.RPA requires some basic skills for learning it with capable of understanding the business requirements and convert them into Automated Process using some RPA tools like Blue Prism, UiPath, Automated Anywhere, and so on.

Thankfully, learning RPA need not any in-depth knowledge on coding, because all the RPA tools have kind of unique mechanism to learn it quickly and deeply. However, you need to develop your logical and analytical skills and strong future is guaranteed for the one who is practicing on it.

Here, the list of skills given below which are required for learning RPA and we are sure it will help you to equip for the better software development and outshine your skills in developing RPA applications.

  • Basic Knowledge in VB and .Net framework as most of the RPA tools are developed in it.
  • Understanding of VBA Macros, Excel, and its implementation
  • Fundamental of writing and integrating Python scripts with RPA toolset
  • Basic understanding about building components like Auto-ML, NLP, and AI integrations such as Microsoft Luis or IBM Watson
