Improving Weakly Supervised Visual Grounding by Contrastive Knowledge Distillation

This repository is the official implementation of CVPR 2021 paper: Improving Weakly Supervised Visual Grounding by Contrastive Knowledge Distillation.

Requirements

  • Tensorflow-1-15

Training

To train the NCE model(s) in the paper, run this command:

python train_nce_distill_model.py \
  --region_feat_path=region_features.hdf5 \
  --phrase_feat_path=phrase_features.hdf5 \
  --glove_path=glove.hdf5

To train the NCE+Distill model(s) in the paper, run this command:

python train_nce_distill_model.py \
  --region_feat_path=region_features.hdf5 \
  --phrase_feat_path=phrase_features.hdf5 \
  --glove_path=glove.hdf5 \
  --phrase_to_label_json=phrase_to_label.json

Evaluation

To evaluate the model on Flickr30K, run:

python eval_model.py \
  --region_feat_path=region_features_test.hdf5 \
  --phrase_feat_path=phrase_features_test.hdf5 \
  --glove_path=glove.hdf5 \
  --restore_path=checkpoint.meta

Pre-trained Models

You can download pretrained models using Res101 VG features here:

You can also find the features on Flickr30K test split here.

The pretrained models achieve the following performance on Flickr30K test split:

Model Name [email protected] [email protected] [email protected]
NCE+Distill 0.5310 0.7394 0.7875
NCE 0.5135 0.7338 0.7833
