Finding Label and Model Errors in Perception Data With Learned Observation Assertions

This is the project page for Finding Label and Model Errors in Perception Data With Learned Observation Assertions.

Please read the paper for full technical details.

Installation

In the root directory, run

pip install -e .

Examples

We provide an example of the Lyft Level 5 percetion dataset. We have provided model predictions for convenience, but you will need to download the dataset here.

All of the scripts are available in examples/lyft_level5. In order to run the scripts, do the following:

1. Set the data directories in constants.py.
2. Learn the priors with learn_priors.py.
3. Run LOA with prior_lyft.py.

You can visualize the results with viz_track.py.
