Smooth_AP

code for the ECCV '20 paper "Smooth-AP: Smoothing the Path Towards Large-Scale Image Retrieval"

The PyTorch implementation of the Smooth-AP loss function is found in src/Smooth_AP_loss.py

Training code and pre-trained weights coming soon...

Dependencies

• Python 3.7.7
• PyTorch 1.6.0
• Cuda 10.1

Data

This repository is used for training using Smooth-AP loss on the following datasets:

• PKU Vehicle ID (obtained from this website https://pkuml.org/resources/pku-vehicleid.html - must email authors for download permission)
• INaturalist (2018 version - obtained from this website https://www.kaggle.com/c/inaturalist-2018/data)

We are the first to use the large-scale INaturalist dataset for the task of image retreival. The dataset splits can be downloaded here: https://drive.google.com/file/d/1sXfkBTFDrRU3__-NUs1qBP3sf_0uMB98/view?usp=sharing . Unpack the zip into the INaturalist dataset directory.

Training the model

training results for the Vehicle ID and Inaturalist datasets can be replicated using this repository. To train the model on the Vehicle ID dataset, you can run:

• python main.py --fc_lr_mul 1 --bs 384
