      public FMClassificationTrainer(LabelObjective objective, StochasticGradientOptimiser optimiser, int epochs, int loggingInterval, int minibatchSize, long seed, int factorizedDimSize, double variance)
      Constructs an SGD trainer for a factorization machine.
      Parameters:
      objective - The objective function to optimise.
      optimiser - The gradient optimiser to use.
      epochs - The number of epochs (complete passes through the training data).
      loggingInterval - Log the loss after this many iterations. If -1 don't log anything.
      minibatchSize - The size of any minibatches.
      seed - A seed for the random number generator, used to shuffle the examples before each epoch.
      factorizedDimSize - Size of the factorized feature representation.
      variance - The variance of the initializer.
