cddc368533 [numex] adding one form of normalization which strips ordinal suffixes so {96th, Ninety-sixth} => 96. This is an additional form of normalization, so there's still one form where the suffixes are kept. One case that's still not handled is something like "IXe Arrondissement" 2017-04-18 21:39:54 -04:00

Hosting model files and training data on CloudFront CDN

d2732922c2 [data] deployed model files and training data to CloudFront for easier downloading around the world and in places like China where the Great Fire Wall may prevent large downloads from abroad. TTL is set to 0 so it still caches the files themselves but checks with origin for the If-Modified-Since headers, allowing the files to be updated dynamically 2017-04-17 14:11:44 -04:00

413c584f08 [fix] need to set prev_state to the NULL state in numex parsing after a non-space/non-hyphen is encountered and the previous match, if any, is added to the result array 2017-04-13 16:01:46 -04:00

f9b57dbd42 [fix] don't use unnamed fields in initializers 
GCC did not support assigning to unnamed fields from designated
initializers until 4.6 [1]. Unfortunately, CentOS 6 ships with GCC 4.4,
so avoiding this C99 feature is necessary to fix building in CentOS 6
environments.

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).
