class FMClassifier extends ProbabilisticClassifier[Vector, FMClassifier, FMClassificationModel] with FactorizationMachines with FMClassifierParams with DefaultParamsWritable with Logging

Factorization Machines learning algorithm for classification. It supports normal gradient descent and AdamW solver.

The implementation is based upon: S. Rendle. "Factorization machines" 2010.

FM is able to estimate interactions even in problems with huge sparsity (like advertising and recommendation system). FM formula is:

$$ \begin{align} y = \sigma\left( w_0 + \sum\limits^n_{i-1} w_i x_i + \sum\limits^n_{i=1} \sum\limits^n_{j=i+1} \langle v_i, v_j \rangle x_i x_j \right) \end{align} $$
First two terms denote global bias and linear term (as same as linear regression), and last term denotes pairwise interactions term. v_i describes the i-th variable with k factors.

FM classification model uses logistic loss which can be solved by gradient descent method, and regularization terms like L2 are usually added to the loss function to prevent overfitting.

    Check transform validity and derive the output schema from the input schema.

    We check validity for interactions between parameters during transformSchema and raise an exception if any parameter value is invalid. Parameter value checks which do not depend on other parameters are handled by Param.validate().

    Typical implementation should first conduct verification on schema change and parameter validity, including complex parameter interaction checks.

    Derives the output schema from the input schema and parameters, optionally with logging.

    This should be optimistic. If it is unclear whether the schema will be valid, then it should be assumed valid until proven otherwise.
