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. We will be focusing on learning a very (probably the most) scalable classification model—logistic regression. We will be exploring what logistic function is, how to train a logistic regression model, adding regularization to the model, and variants of logistic regression that are applicable to very large datasets. 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, ...
