Ranked-List-Loss-for-Deep-Metric-Learning

[Paper] [Slides] [Poster]

Code is under legal check. Please feel free to drop me an email if you want it for academic use only.

This work is being extended for TPAMI submission, with the main target to improve this work further.

The updated codes are released. Feel free to have a try!
In Unbiased Evaluation of Deep Metric Learning Algorithms--Istvan Feh ´ erv ´ ari etal 2019, it stated "On the SOP dataset, we never managed to make this algorithm converge." using Ranked List Loss.
- First of all, I thank their interest in our work, which is inspiring for me and my collaborators.
- However, their statement is not the fact. Please check our reproducible results.

Dependencies and Setup

The core functions are implemented using C++ in the caffe framework. We use matlab interfaces matcaffe for data preparation.

Clone our repository: Simply copy and execute following commands in the command line

git clone git@github.com:XinshaoAmosWang/Ranked-List-Loss-for-D
eep-Metric-Learning.git
cd Ranked-List-Loss-for-Deep-Metric-Learning/

Install dependencies on Ubuntu 16.04

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install --no-install-recommends libboost-all-dev
sudo apt-get install libopenblas-dev
sudo apt-get install python-dev
sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev

Install MATLAB 2017b

Download and Run the install binary file
```
./install
```
Compile Caffe and matlab interface

Note you may need to change some paths in Makefile.config according your system environment and MATLAB path
```
cd CaffeMex_RLL_GR_V03_Simp
make -j8  && make matcaffe
```

Usage

Training on Stanford Online Product dataset.

Data preparation for SOP

Downlaod Stanford_Online_Products dataset from ftp://cs.stanford.edu/cs/cvgl/Stanford_Online_Products.zip

For simplicity, you can use the data mat file in pre_post_process directory, which is ready training and testing scripts. To solve the data path, you can do eithor a or b:
```
a. Changing the path within the mat files. 
b. A Simpler way: Create a soft link of your data
e.g sudo ln -s /.../Stanford_Online_Products /home/xinshao/Papers_Projects/Data/Stanford_Online_Products
```
Train & Test

Run the training and testing scripts in the training folder of a specific setting defined by its corresponding prototxt folder.

Training on In-shop Clothes

Procedures are similar to SOP
Please see training scripts in Folder InshopClothes_Simp_21042020

Our trained models on SOP, In-shop Clothes

Training on custom datasets

You only need to create training/testing mat files with the same structure as SOP_TrainImagePathBoxCell.mat and SOP_TestImagePathBoxCell.mat in directory SOP_GoogLeNet_Ori_V05/pre_pro_process.

e.g. SOP_TrainImagePathBoxCell.mat contains , TrainImagePathBoxCell storing all image paths and class_ids storing their corresponding semantic labels.

Application on person re-identification

Training scripts on Market1501 dataset are given in Folder Market1501_GooLeNetV2_V02_11042020;
Scripts on data processing are in Folder Market-1501_baseline-v16.01.14

Common questions

1. What does ranking mean?

Given a query, the objective is to rank its postive set in front of its negative set by a distance margin.
We do not need to consider the exact order of examples within the positive and negative sets.

2. How is a loss function related with deep metric learning?

Please see our discussion in the paper.
