What did you find confusing? Please describe.
The current docs for the 1p algorithms have incomplete docstrings for each algorithm's Model and Predictor.
For example, the FactorizationMachinesModel class and the FactorizationMachinePredictor class are having empty doc strings.
The same issue for the rest of algorithms.
Describe how documentation can be improved
Add docstrings for the 1-p algorithms' Model and Predictor classes.
