5dfdd4b7eb [language_classification] Runtime language classifier can now use dense or sparse weights, with a different header signature for the sparse version (using old signature for the dense version, so backward-compatible) 2017-04-02 23:51:54 -04:00

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.

cf88bc7f65 [optimization] implemented Google's FTRL-Proximal, adapted for the multiclass/multinomial case. It is L1 and L2 regularized, and should both encourage sparsity with the L1 penalty while being robust to collinearity of features due to the L2 penalty.

96e1ca5e89 [utils] sparse_matrix_add_unique_columns_alias, adds the actual column indices to hashtable/array and aliases those in the table from 1 to N (where N is the number of unique columns in this batch).
