	//   sgd.l1RegularizationAmount - Coefficient regularization L1 norm. It controls
	// overfitting the data by penalizing large coefficients. This tends to drive
	// coefficients to zero, resulting in sparse feature set. If you use this parameter,
	// start by specifying a small value such as 1.0E-08.
	//
	// The value is a double that ranges from 0 to MAX_DOUBLE. The default is not
	// to use L1 normalization. The parameter cannot be used when L2 is specified.
	// Use this parameter sparingly.
	//
	//   sgd.l2RegularizationAmount - Coefficient regularization L2 norm. It controls
	// overfitting the data by penalizing large coefficients. This tends to drive
	// coefficients to small, nonzero values. If you use this parameter, start by
	// specifying a small value such as 1.0E-08.
	//
	// The valuseis a double that ranges from 0 to MAX_DOUBLE. The default is not
	// to use L2 normalization. This cannot be used when L1 is specified. Use this
	// parameter sparingly.
	//
	//  sgd.maxPasses - Number of times that the training process traverses the
	// observations to build the MLModel. The value is an integer that ranges from
	// 1 to 10000. The default value is 10.
	//
