At the bottom of these sections, add links to the generated API docs for the different algorithms (e.g. `RidgeRegressionWithSGD`, `LassoRegressionWithSGD`, etc). The links will be of the form `api/mllib/index.html#org.apache.spark.mllib.regression.RidgeRegressionWithSGD`. It's fine to just have a list of algorithms in each section.
