JumpStart to Python for Data Science

SS Course: GK100669

Course Overview


Data science is a fast growing new knowledge domain used by organizations to make data driven decisions. Data Scientists wear various hats to work with data and to derive value from it. The Python programming language is an indispensable tool for the data science practitioner and a must-know tool for every aspiring data scientist. Python offers you a fast, reliable, cross-platform, and mature environment for data analysis, machine learning, and algorithmic problem solving.

Beginning with the essentials of Python in data science, you ll learn to manage data and perform linear algebra in Python. You ll apply logistic regression techniques to your applications before creating recommendation engines with various collaborative filtering algorithms and improving your predictions by applying the ensemble methods. Finally, you ll perform K-means clustering, along with an analysis of unstructured data with different text mining techniques, and leveraging the power of Python in big data analytics.

This fast paced and technical course helps you move beyond the hype and transcend the theory by providing you with a hands-on study of data science.
