Machine Learning for Streaming Data with Python

Chapter 7: Online Regression

After looking at online anomaly detection and online classification throughout the previous chapters, there is one large category of online machine learning that remains to be seen. Regression is the family of supervised machine learning models that applies to use cases in which the target variable is numerical.

In anomaly detection and classification, you have seen how to build models to predict categorical targets (yes/no and iris species), but you have not yet seen how to work with a target that is numerical. Working with numerical data requires having methods that work differently, both in the deeper layers of model training and model definition and also in our use of metrics.
