As mentioned in Chapter 1, Getting Started with Machine Learning and ML.NET, classification is broken down into two main categories—two-class and multi-class. In a two-class classifier, also known as a binary classifier, the prediction simply returns 0 or 1. In a multi-class problem, a pre-selected range of return labels, such as virus types or car types, is returned.
There are several binary classification model types available in the machine learning ecosystem to choose from, as follows:
- AveragedPerceptronTrainer
- SdcaLogisticRegressionBinaryTrainer
- SdcaNonCalibratedBinaryTrainer
- SymbolicSgdLogisticRegressionBinaryTrainer
- LbfgsLogisticRegressionBinaryTrainer
- LightGbmBinaryTrainer
- FastTreeBinaryTrainer
- FastForestBinaryTrainer
- GamBinaryTrainer
- FieldAwareFactorizationMachineTrainer
- PriorTrainer
- LinearSvmTrainer
The car-value application we will be creating later in this chapter utilizes the FastTreeBinaryTrainer model.
