Raw

Project Overview

In this project, we'll predict future season stats for baseball players. Specifically, we'll predict the wins above replacement (WAR) a player will generate next season. We'll first download baseball season data using pybaseball and clean it. We'll do feature selection using a sequential feature selector to identify the most promising predictors for machine learning. We'll then train a ridge regression model to predict future season WAR. We'll measure error and improve the model.

At the end, you'll have a model that can predict future season WAR, along with next steps to improve the model.

Project Steps

  • Download baseball season data
  • Clean the data and prepare it for ML
  • Run feature selection
  • Create a machine learning model and estimate accuracy
  • Improve accuracy

Code
