Al	964ac15e51	[language_classification] adding options to language_classifier_train for using SGD with {L2, L1} regularization or FTRL-Proximal using both. ... 1. Creates sparse matrix for L1 SGD and FTRL 2. Uses the one standard-error rule during cross-validation. Parameters within one standard error of the lowest-cost solution are preferred if they are better regularized. 3. Pulls weights matrix for only the features that occurred in a given batch. In the case of FTRL, this needs to be computed each on each batch, so the sparsity helps here.	2017-04-02 23:46:14 -04:00
