Predicting Online Ad Click-Through with Logistic Regression

In this chapter, we will be continuing our journey of tackling the billion-dollar worth problem of advertising click-through prediction.

Besides the application in classification, we will also be discussing how logistic regression and random forest are used in picking significant features. Again, you won't get bored as there will be lots of implementations from scratch, ...
