Python Data Analysis

Summary

This chapter was devoted to predictive modeling and machine learning. These are very large fields to cover in one chapter, so you may want to have a look at some of the books mentioned in the Preface. Predictive analytics uses a variety of techniques, including machine learning, to make useful predictions for instance to determine whether it is going to rain tomorrow.

SVM maps the data points to points in multidimensional space. The classification problem is then reduced to finding a hyperplane or hyperplanes that best separate the points into classes.

The elastic net regularization combines linearly the LASSO and ridge methods. For regression problems, goodness-of-fit is often determined with the coefficient of determination also called ...
