Description

FieldAwareFactorizationMachine is good for large dataset like the Criteo 1TB dataset.

Currently FieldAwareFactorizationMachine is not swept over in AutoML.

Task:

  • Add trainer to default list of binary learners to try
  • Add sweep range
  • Add to CLI's C# CodeGen

Should be easy to just replicate an existing trainer like SDCA: https://github.com/dotnet/machinelearning/blob/d518b587b06ac3896a48646622b0f2169a230855/src/Microsoft.ML.AutoML/TrainerExtensions/BinaryTrainerExtensions.cs#L150-L169

Contributor guide

Research direction
Follow the pattern of existing binary trainer SDCA to add FieldAwareFactorizationMachine: add trainer to default list, add sweep range, and CLI code generation.
