Revision Scoring weekly update - AI

11 May 2016


      Hey folks,
This is the weekly update for the Revision Scoring project for the week of
April 2nd through April 8th.
*New developments:*
- Solved some issues that block a major performance improvement for
   score requests using multiple models[2]
- Improved the performance of feature extraction for features that use
   mwparserfromhell[3,4]
- We applied regex performance optimizations to badwords and informal
   word detection for many languages[9]
*Maintenance and robustness:*
- Solved a regression in ScoredRevisions that caused most revisions in
   RecentChanges to not be scored[1]
- Set ORES load balancer to rebalance on 500 responses from a web node[5]
- Enabled CORS for error responses from ORES -- this makes it easier to
   report errors from a gadget on a wiki[6]
- Sade the staging instance of Wikilabels[7] look a lot more like the
   production instance[8]
