v0.1.0-smartnav

This is a frozen version of the repository to work with SmartNav and SmartHider.

Note that the API diverged a bit between the two projects. SmartHider includes a legacy mode to be compatible with that. By default, this repo works with non-legacy SmartHider. To support legacy/SmartNav, make sure to appropriately modify the METRICS list in train_smartnav.py.
