Description

In this course, we will walk  through the process of using machine learning to solve the problem of which puppy to adopt. We’ll go all the way from defining a good question to building and testing a program to answer it. Along the way, we’ll get to explore and repair a data set, deep dive into model selection and optimization, create some plots of the results, and build a command line interface for getting answers. The star of the show will be a polynomial regression algorithm that we will write from scratch. When you’re done you’ll know how to create a polynomial regressor of any order--linear, quadratic, cubic, or higher--and how to automatically choose the one that best fits your data set. 

Who this course is for:
  • Intermediate machine learning students and data scientists looking to round out their skill set on a realistic problem.
