Description

See this notebook for a overview of our training process. For the pure TIL model, here is quick setup guide:

  1. Go here for the data and model. Password is: niceboat_til2020.
  2. Put the train & val data folders back into til2020. (I already fixed the annotation json)
  3. Download the model (ft-til_resnet101_rcnn_moda_aug-147999-best_val.pth) and place it into final_ckpts.
  4. To add more augmentation components, see pipeline.py.

Most of the important logic has been extracted into their own python files which can be found in the scripts folder, which also contains some utility scripts. There may also be other utility scripts scattered elsewhere for the purpose of wrangling datasets.

Citations

The library used is Facebook's Detectron2. The model is R101-FPN aka ResNet-101 with Feature Pyramid Network. As such, we need to cite:

@misc{wu2019detectron2,
  author =       {Yuxin Wu and Alexander Kirillov and Francisco Massa and
                  Wan-Yen Lo and Ross Girshick},
  title =        {Detectron2},
  howpublished = {\url{https://github.com/facebookresearch/detectron2}},
  year =         {2019}
}

Ultimately, we found the TIL dataset insufficient and after researching and experimenting with multiple datasets, we stumbled across Modanet, annotations based on the Paper Doll dataset that were of extremely high quality, allowing our model to reach much greater AP scores.

  title        = {ModaNet: A Large-Scale Street Fashion Dataset with Polygon Annotations},

  booktitle    = {ICCV 2013},
  year =         {2013}
}

One last dataset we used was the DeepFashion2 Dataset. It is a very large dataset, and unfortunately too good to be true, being of low quality as evidenced by our tried and tested models being unable to train well on it.
