Data Science Fundamentals LiveLessons teaches you the foundational concepts, theory, and techniques you need to know to become an effective data scientist. The videos present you with applied, example-driven lessons in Python and its associated ecosystem of libraries, where you get your hands dirty with real datasets and see real results.

If nothing else, by the end of this video course you will have analyzed a number of datasets from the wild, built a handful of applications, and applied machine learning algorithms in meaningful ways to get real results. And along the way you learn the best practices and computational techniques used by a professional data scientist. More specifically, you learn how to acquire data that is openly accessible on the Internet by working with APIs. You learn how to parse XML and JSON data to load it into a relational database.

What You Will Learn

  • How to get up and running with a Python data science environment
  • The essentials of Python 3, including object-oriented programming
  • The basics of the data science process and what each step entails
  • How to build a simple (yet powerful) recommendation engine for Airbnb listings
  • Where to find quality data sources and how to work with APIs programmatically
  • Strategies for parsing JSON and XML into a structured form
  • The basics of relational databases and how to use an ORM to interface with them in Python
  • Best practices of data validation, including common data quality checks

Who Should Take This Course

  • Aspiring data scientists looking to break into the field and learn the essentials necessary
  • Journalists, consultants, analysts, or anyone else who works with data and looking to take a programmatic approach to exploring data and conducting analyses
  • Quantitative researchers interested in applying theory to real projects and taking a computational approach to modeling.
  • Software engineers interested in building intelligent applications driven by machine learning
  • Practicing data scientists already familiar with another programming environment looking to learn how to do data science with Python
