SGRAF

PyTorch implementation for AAAI2021 paper of “Similarity Reasoning and Filtration for Image-Text Matching”.

It is built on top of the SCAN and Cross-modal_Retrieval_Tutorial.

We have released two versions of SGRAF: Branch main for python2.7; Branch python3.6 for python3.6.

Requirements

We recommended the following dependencies for Branch main.

• Python 2.7
• PyTorch (>=0.4.1)
• NumPy (>=1.12.1)
• TensorBoard
• Punkt Sentence Tokenizer:

import nltk
nltk.download()
> d punkt

Download data and vocab

We follow SCAN to obtain image features and vocabularies, which can be downloaded by using:

wget https://iudata.blob.core.windows.net/scan/data.zip
wget https://iudata.blob.core.windows.net/scan/vocab.zip

Another download link is available below：

https://drive.google.com/drive/u/0/folders/1os1Kr7HeTbh8FajBNegW8rjJf6GIhFqC

Pre-trained models and evaluation

Modify the model_path, data_path, vocab_path in the evaluation.py file. Then run evaluation.py:

python evaluation.py

Note that fold5=True is only for evaluation on mscoco1K (5 folders average) while fold5=False for mscoco5K and flickr30K. Pretrained models and Log files can be downloaded from Flickr30K_SGRAF and MSCOCO_SGRAF.

Training new models from scratch

Modify the data_path, vocab_path, model_name, logger_name in the opts.py file. Then run train.py:

For MSCOCO:

(For SGR) python train.py --data_name coco_precomp --num_epochs 20 --lr_update 10 --module_name SGR
(For SAF) python train.py --data_name coco_precomp --num_epochs 20 --lr_update 10 --module_name SAF

For Flickr30K:

(For SGR) python train.py --data_name f30k_precomp --num_epochs 40 --lr_update 30 --module_name SGR
(For SAF) python train.py --data_name f30k_precomp --num_epochs 30 --lr_update 20 --module_name SAF
