Course Overview

Data is the residue of every action that takes place in a company, with customers, and in the marketplace. It is created when customers buy products, users interact with services, and colleagues collaborate.

In an increasingly connected world, our ability to capture and leverage data has increased exponentially; but data in the wrong hands is useless, if not dangerous. In the right hands, data can drive new insights and powerfully informed decisions. This course introduces fundamental techniques and technologies from data science, predictive analytics, and machine learning that can help you get a handle on the modern information flood. Using the Python programming language, you will learn:

  • Analytics skills which will enable you to evaluate, query, and visualize data using open source tools: NumPy, Pandas, Matplotlib, Seaborn, and scikit-learn.
  • Strategies to create data-driven questions that can provide scientific or business value
  • Methods for assembling data from multiple sources and preparing powerful machine learning (ML) models
  • Techniques for deploying models as part of larger systems
