Generative model and discriminative model

Discriminative models

  • Model P(Y|X)

  • Construct a single model for all the data

  • Predict labels based on observed data

  • Requires fewer data, fast, good performance even with small dataset

Generative models

  • Model P(X,Y)

  • Need to construct a model for each label (yi). During prediction, select yi based on the highest probability from each of the model of yi. So no boundary.

  • Need a lot of data to build the model, but the information is complete. Can do more than predicting labels.
