Our approach on OpenImages Dataset.

Training and Evaluation

NUS-WIDE

Step 1: Data preparation

  1. Download pre-computed features from here and store them at features folder inside BiAM/datasets/NUS-WIDE directory.
  2. [Optional] You can extract the features on your own by using the original NUS-WIDE dataset from here and run the below script:
python feature_extraction/extract_nus_wide.py

Step 2: Training from scratch

To train and evaluate multi-label zero-shot learning model on full NUS-WIDE dataset, please run:

sh scripts/train_nus.sh

Step 3: Evaluation using pretrained weights

To evaluate the multi-label zero-shot model on NUS-WIDE. You can download the pretrained weights from here and store them at NUS-WIDE folder inside pretrained_weights directory.

sh scripts/evaluate_nus.sh

OPEN-IMAGES

Step 1: Data preparation

  1. Please download the annotations for training, validation, and testing into this folder.

  2. Store the annotations inside BiAM/datasets/OpenImages.

  3. To extract the features for OpenImages-v4 dataset run the below scripts for crawling the images and extracting features of them:

## Crawl the images from web
python ./datasets/OpenImages/download_imgs.py  #`data_set` == `train`: download images into `./image_data/train/`
python ./datasets/OpenImages/download_imgs.py  #`data_set` == `validation`: download images into `./image_data/validation/`
python ./datasets/OpenImages/download_imgs.py  #`data_set` == `test`: download images into `./image_data/test/`

## Run feature extraction codes for all the 3 splits
python feature_extraction/extract_openimages_train.py
python feature_extraction/extract_openimages_test.py
python feature_extraction/extract_openimages_val.py

Step 2: Training from scratch

To train and evaluate multi-label zero-shot learning model on full OpenImages-v4 dataset, please run:

sh scripts/train_openimages.sh
sh scripts/evaluate_openimages.sh

Step 3: Evaluation using pretrained weights

To evaluate the multi-label zero-shot model on OpenImages. You can download the pretrained weights from here and store them at OPENIMAGES folder inside pretrained_weights directory.

sh scripts/evaluate_openimages.sh
