What Is a Support Vector Machine?
In the previous chapter, you saw how to perform classification using logistics regression. In this chapter, you will learn another supervised machine learning algorithm that is also very popular among data scientists—Support Vector Machines (SVM). Like logistics regression, SVM is also a classification algorithm.
The main idea behind SVM is to draw a line between two or more classes in the best possible manner (see Figure 8.1).

Once the line is drawn to separate the classes, you can then use it to predict future data. For example, given the snout length and ear geometry of a new unknown animal, you can now use the dividing line as a classifier to predict if the animal is a dog or a cat.
In this chapter, you will learn how SVM works and the various techniques you can use to adapt SVM for solving nonlinearly‐separable datasets.
