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 [email protected]: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

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

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.
