Features

Approach..• Brainstorm features: Really get into the problem, look at a lot of data,

study feature engineering on other problems and see what you can steal.• Devise features: Depends on your problem, but you may use automatic

feature extraction, manual feature construction and mixtures of the two• Select features: Use different feature importance scorings and feature

selection methods to prepare one or more “views” for your models to operate upon.• Evaluate models: Estimate model accuracy on unseen data using the

chosen features
