Boundary-aware Backward-Compatible Representation via Adversarial Learning in Image Retrieval [PDF]

Introduction

Backward-compatible training (BCT) aims to deploy a new model without the operation of "backfilling". We introduce AdvBCT, an Adversarial Backward-Compatible Training method with an elastic boundary constraint that takes both compatibility and discrimination into consideration. The codes for AdvBCT and the benchmark are all publicly available in this repo. Thanks to the work Hot-refresh. Some implementaions of our code are based on it.

Our paper has been accepted by CVPR2023.

Datasets

refer to Dataset.md.

Enviroments

conda create -n bct python=3.7
conda activate bct
#conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda install faiss-cpu
pip install -r requirements.txt

Train

• run scripts/train_old.sh to train the old model. change configs/old_model.yml, MODEL.ARCH, TAG, and TRAIN.FILE_DIR to set different allocation types.
• run scripts/extract_feat.sh to get feature centers with the old model.
• run scripts/train_new.sh to train new models. change configs/new_*.yml to configure different allocation types.

Evaluation

evaluate datasets on 32G v100

mkdir -p output/final_model

• move models to ./output/final_model/. Models can be download in GDrive. The password is 9168.
• test. change model paths and arch to test your models.

bash scripts/test.sh landmark roxford5k ./data/ROxfordParis/
bash scripts/test.sh landmark rparis6k ./data/ROxfordParis/
bash scripts/test.sh landmark gldv2 ./data/GLDv2 # take a long time
