BDC project 记录

\section{Problem Definition}

There is a data set of records on drug reviews, and we need to develop algorithms to predict the rating level of a drug given by a review. In other words, this is a text classification problem. Comments, useful count, side effect and others are our features (X), and rating is our label (Y).
