4. Multiclass Classification with RandomForest
This chapter will show you how to train a multiclass classifier using the Random Forest algorithm. You will also see how to evaluate the performance of multiclass models.
By the end of the chapter, you will be able to implement a Random Forest classifier, as well as tune hyperparameters in order to improve model performance.
In the previous chapter, you saw how to build a binary classifier using the famous Logistic Regression algorithm. A binary classifier can only take two different values for its response variables, such as 0 and 1 or yes and no. A multiclass classification task is just an extension. Its response variable can have more than two different values.
