_Objective:_ Predict labels using a very large dataset with noisy labels and a much smaller (3 orders of magnitude) dataset with human-verified annotations.

_Dataset:_ [Open image](https://research.googleblog.com/2016/09/introducing-open-images-dataset.html)


## Architecture:

Contrary to other approaches they use the clean labels, the noisy labels but also image features. They basically train 3 networks:

1.  A feature extractor for the image.
2.  A label Cleaning Network that predicts to learn verified labels from noisy labels + image feature.
3.  An image classifier that predicts using just the image.

## Results:

Overall better performance but not breath-taking improvement: from `AP 83.832 / MAP 61.82` for a NN trained only on labels to `AP 87.67 / MAP 62.38` with their approach.
