# Build better training data

## Overview

• Identify the importance of preprocessing data sets
• Introduce the recipes package for preprocessing data
• Utilize usemodels to automatically construct code templates for common model types
• Construct workflows for machine learning

## Before class

This is not a math/stats class. In class we will briefly summarize how these methods work and spend the bulk of our time on estimating and interpreting these models. That said, you should have some understanding of the mathematical underpinnings of statistical learning methods prior to implementing them yourselves. See below for some recommended readings:
