COSC 410LA S25 Lab 4: Classification Competition

This Lab is due Sunday, Sep 28, 2025 at 11:59PM.

Introduction

The goal of this lab to expand on your familiarity with a standard machine learning pipeline. You’ll explore a weather prediction data set. Then, you’ll implement a function for fitting a classification model of your choosing on this dataset. By completing the lab, you will demonstrate that you understand

• how to preprocess data in a standard ML pipeline
• how to select a good model for your task
• the ability to hyperparameter tune
• how to work with leaderboards
