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.
+ `sgd.maxMLModelSizeInBytes` - Maximum allowed size of the model.
