Hey,

This is the 29th weekly update from revision scoring team that we have sent
to this mailing list.

Deployments:

   - We deployed logging changes to ORES that will reduce the verbosity[1]


   - We also deployed revscoring 1.3.0 and new models built with it to WMF
   labs[2].  This won't change anything important from a user-perspective, but
   it paves the way for developing new modeling strategies.


Maintenance and robustness:

   - We fixed puppet so that log file directories are also created on the
   celery worker nodes (affects wmflabs)[3]


   - We fixed an issue with our recall_at_fpr metrics which was incorrectly
   defined and implemented a recall_at_precision metric to take its place[4]


New development:

   - We've made a lot of progress on modeling sentences and have just
   started experimenting with a sentence model from featured articles[5]


   - We're reviewing a dataset of spam/vandalism/attack new page creations
   for public release[6].  This dataset will help our collaborators work with
   us on modeling the quality of drafts and supporting new page triage.
