Cross-Batch Memory for Embedding Learning (XBM)

Code for the CVPR 2020 paper (accepted as Oral) Cross-Batch Memory for Embedding Learning

XBM: A New SOTA Method for DML

• Great Improvement: XBM can improve R@1 by 12~25% on three large-scale datasets

• Memory Efficient: with less than 1GB for large-scale datasets

• Elegant Algorithm: with an implementation that can be achieved in only several lines

Installation

pip install -r requirements.txt
python setup.py develop build

Training and Evaluation

CUDA_VISIBLE_DEVICES=0 python3 tools/train_net.py --cfg configs/sample_config.yaml
