PyTorch implementation for "Learning to Rematch Mismatched Pairs for Robust Cross-Modal Retrieval (CVPR 2024)"

Learning to Rematch Mismatched Pairs for Robust Cross-Modal Retrieval

Requirements

• Python 3.8
• torch 1.12
• numpy
• scikit-learn
• pomegranate Install. Note that pomegranate requires Cython=0.29, NumPy, SciPy, NetworkX, and joblib. Then you can run python setup.py build and python setup.py install to install it.)
• Punkt Sentence Tokenizer:

import nltk
nltk.download()
> d punkt

Datasets

We follow NCR to obtain image features and vocabularies.

Noise (Mismatching) Index

We use the same noise index settings as DECL and RCL, which could be found in noise_index. The mismatching ratio (noise ratio) is set as 0.2, 0.4, 0.6, and 0.8.

Training and Evaluation
