Lab 3: Text Classification

In this week's lab, you'll get to experiment with text classification!

Let's Go!

As always, start by creating a new GitHub repo from the starter code template:

• Link to Lab 3 starter code

This lab provides the following starter files:

• PCLDataReader.py
• pcl_main.py

We also provide a minimalist test suite for the classes you will be implementing:

• test-pcl.py

As always, the tests are mostly just to ensure that your code is following the specifications so that you don't end up doing analysis based on results that are way off from what we intended. They are not meant to catch every possible bug, and you should feel free to do your own testing (and, if you do so, talk about it in your journal).
