Using reverted changesets for model training

Open bkowshik opened this issue 7 years ago • 5 comments

Per text with @batpad,

Changeset comment has revert

There are a total of 13,125 changesets on osmcha with revert in the changeset comment. Interestingly, 2,505 (20%) changesets are one feature modification changesets which is what we use in the latest version of Gabbar.

Assuming, mappers revert a problematic or wrong feature in these one feature modification changesets, this could be an additional dataset we could make use of for the current iteration of the feature level classifier of Gabbar. I manually :eyes: a couple of these changesets and they are definitely want we want to catch with Gabbar.

Changesets from revert user accounts

Mappers and DWG sometimes maintain a separate account for reverts. Changesets from these accounts will be interesting to look at as well. Ex:
