Thanks for the detailed explanation, Aaron. As
always your work is a
model in transparency for the rest of us :)

Hi Luis! Thanks for taking a look.
First, I should say that false-positives should be expected. We're
working on better signaling in the UI so that you can differentiate the
edits that ORES is confident about and those that it isn't confident about
-- but are still worth your review.
So, in order to avoid a bias feedback loop, we don't want to feed any
observations you made *using* ORES back into the model -- since ORES'
prediction itself could bias your assessment and we'd re-perpetuate that
bias. Still, we can use these misclassification reports to direct our
attention to problematic behaviors in the model. We use the Wiki Labels
system to gather reviews of random samples of edits from Wikipedians in
order to train the model.
We're still working out the Right(TM) way to report false positives.
Right now, we ask that you do so on-wiki and in the future, we'll be
exploring a nicer interface so that you can report them while using the
tool. We review these misclassification reports manually to focus our work
on the models and to report progress made. This data is never directly
used in training the machine learning models due to issues around bias.
*Wiki labels campaigns:*
In order to avoid the biases in who gets reviewed and why, we generate
random samples of edits for review using our Wiki Labels system. We've
completed a labeling campaign for English Wikipedia, but we could run an
additional campaign to gather more data. I'll get that set up and respond
to this message when it is ready.

Very cool! Is there any way for users of this
tool to help train it?
For example, the first four things it flagged in my watchlist were all
false positives (next 5-6 were correctly flagged.) It'd be nice to be able
to contribute to training the model somehow when we see these
