You are required to build a text classifier that can predict whether a given text is relevant or not. The target column is called "relevance". It has 3 values - no (6571), yes (1420), and not sure (9). Turn this into a binary classification problem ("yes" or "no") by deleting rows where relevance = "not sure".

You will have to preprocess the data to get reasonable accuracies. Try the following algorithms: Naive Bayes, Logistic Regression, and Random Forest. Also, use the Lime Text Explainer to identify the words that are most likely to predict relevance (i.e., "yes") vs non-relevance (i.e., "no").

You will do everything in a single IPython notebook. Submit the IPython notebook by the deadline.

Below is the format of the data:
