Hey, This is the 22nd weekly update from revision scoring team that we have sent to this mailing list.
UI work: - We configured the default threshold for the ORES review tool on Wikidata to be more strict (higher recall, lower precision)[1] - We fixed a display issue on Special:Contributions where the filters would not wrap[2] Increasing model fitness: - We finished demonstrating model fitness gains using hash-vector features[3]. Next, we'll be working to get the hash-vector features implemented in revscoring/ORES[4]. - We implemented a new strategy for training and testing on all data using cross-validation[5]. This will both increase the fitness of the models and make the statistics reported more robust. Maintenance and robustness - We fixed an indexing issues in ores_model that prevented the deployment of updated models[6]. - We did a minor investigation to a short period of degraded service quality on WMF Labs[7] 1. https://phabricator.wikimedia.org/T144784 -- Change default threshold for Wikidata to high 2. https://phabricator.wikimedia.org/T143518 -- Filter on user contribs has nowrap, causing issues 3. https://phabricator.wikimedia.org/T128087 -- [Spike] Investigate HashingVectorizer 4. https://phabricator.wikimedia.org/T145812 -- Implement ~100 most important hash vector features in editquality models 5. https://phabricator.wikimedia.org/T142953 -- Train on all data, Report test statistics on cross-validation 6. https://phabricator.wikimedia.org/T144432 -- oresm_model index should not be unique 7. https://phabricator.wikimedia.org/T145353 -- Investigate short period of ores-web-03 insanity Sincerely, Aaron from the Revision Scoring team _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
