Course Description

Data Science

What is data science? Data science is the field of study on the data available on domain expertise, programming skills and knowledge of mathematics and statistics to draw meaningful and useful insights from the data. Data Science is a mix of various tools, algorithms and machine learning principles with an objective to find hidden patterns from the raw data. 
 

As the era of big data has emerged and demand has gone up for its storage. It became a major challenge and concern for the industry till a decade ago. A focus is laid on building a framework and finding solutions to store data. With the emergence of a key tool like Hadoop and other frameworks, the storage of data has been resolved to the maximum extent and now the focus of the industry migrated into the processing of the data. Undoubtedly, Data Science is the future of Artificial Intelligence (AI). Hence, it attained significance to understand what Data Science is. The industry thinks how the data can be used and it can be made a value-added service to the enterprise.

The course provides fundamentals of data preparation, predictive modelling, data science and the development. Various models of maintenance will be introduced in a corporate environment following a tested project methodology. The candidates will be trained in fundamental challenges, understanding the business problem and identifying the appropriate analytical approach to tackle the issues. The training includes data preparation, selecting variables and data encoding. A wide range of algorithms includes decision trees, regression, neuro networks, basket analysis and simulation.
