What is Where by Looking: Weakly-Supervised Open-World Phrase-Grounding without Text Inputs - NIPS 22'

Get Started

  • datasets format are followed by link

For training a model :

python train_grounding.py -bs 32 -nW 8 -nW_eval 1 -task vg_train -data_path /path_to/vg -val_path /path_to/flicker
python train_grounding.py -bs 32 -nW 8 -nW_eval 1 -task coco -data_path /path_to/coco -val_path /path_to/flicker

For Grounding evaluation with our model [XX is the number of the results folder i.e 'gpu22' - XX == 22]:

python inference_grounding.py -task grounding -dataset refit -val_path /path_to/RefIt -Isize 224 -clip_eval 0 -path_ae XX -nW 1
python inference_grounding.py -task grounding -dataset flicker -val_path /path_to/flicker -Isize 224 -clip_eval 0 -path_ae XX -nW 1
python inference_grounding.py -task grounding -dataset vg -val_path /path_to/VG -Isize 224 -clip_eval 0 -path_ae XX -nW 1

For Grounding evaluation with CLIP model:

python inference_grounding.py -task grounding -dataset refit -val_path /path_to/RefIt -Isize 224 -clip_eval 1 -nW 1
python inference_grounding.py -task grounding -dataset flicker -val_path /path_to/flicker -Isize 224 -clip_eval 1 -nW 1
python inference_grounding.py -task grounding -dataset vg -val_path /path_to/VG -Isize 224 -clip_eval 1 -nW 1

For WWbL evaluation with our model:

python inference_grounding.py -task app -dataset refit -val_path /path_to/RefIt -Isize 224 -clip_eval 0 -path_ae XX -nW 1 --start 0 --end 9983
python wwbl_algo1_point_metric.py -nW 1 -predictions_path YY -val_path /path_to/RefIt --dataset refit

python inference_grounding.py -task app -dataset flicker -val_path /path_to/flicker -Isize 224 -clip_eval 0 -path_ae XX -nW 1 -start 0 -end 1000
python wwbl_algo1_point_metric.py -nW 1 -predictions_path YY -val_path /path_to/flicker --dataset flicker

python inference_grounding.py -task app -dataset vg -val_path /path_to/VG -Isize 224 -clip_eval 0 -path_ae XX -nW 1 -start 0 -end 17478
python wwbl_algo1_point_metric.py -nW 1 -predictions_path YY -val_path /path_to/VG --dataset VG
