LoRS: Low-Rank Similarity Mining

Paper

This repo contains code of our ICML'24 work LoRS: Low-Rank Similarity Mining for Multimodal Dataset Distillation. LoRS propose to learn the similarity matrix during distilling the image and text. The simple and plug-and-play method yields significant performance gain. Please check our paper for more analysis.

Getting Started

Requirements: please see requirements.txt.

Pretrained model checkpoints: you may manually download checkpoint of BERT, NFNet (from TIMM) and put them here:

distill_utils/checkpoints/
├── bert-base-uncased/
│   ├── config.json
│   ├── LICENSE.txt
│   ├── model.onnx
│   ├── pytorch_model.bin
│   ├── vocab.txt
│   └── ......
└── nfnet_l0_ra2-45c6688d.pth

Datasets: please download Flickr30K: [Train][Val][Test][Images] and COCO: [Train][Val][Test][Images] datasets, and put them here:

./distill_utils/data/
├── Flickr30k/
│   ├── flickr30k-images/

│   └── readme.txt
└── COCO/
    ├── train2014/
    ├── val2014/
    └── test2014/

Training Expert Buffer: e.g. run sh sh/buffer_flickr.sh. The expert training takes days. You could manually split the num_experts and run multiple processes.

Distill with LoRS: e.g. run sh sh/distill_flickr_lors_100.sh. The distillation could be run on one single RTX 3090/4090 thanks to TESLA.
