                              Learning Distance for Sequences by Learning a Ground Metric

1. Introduction.

This package includes the prototype MATLAB codes and data for experiments on the MSR Action3D dataset and the ChaLearn dataset, described in

	"Learning Distance for Sequences by Learning a Ground Metric", Bing Su and Ying Wu. ICML, 2019.

The 60-dimensional frame-wide features are employed as described in the supplementary file.

"MSRAction3D" and "ChaLearn" tested under Windows 7 x64, Matlab R2015b.

"ChaLearn_Deep" tested under Linux Ubuntu 16.04.2, Matlab R2018a.



2.  Usage & Dependency.

- MSRAction3D --- For the 60-dimensional frame-wide features processed by "https://github.com/InwoongLee/TS-LSTM" (described in "Lee, I., Kim, D., Kang, S., and Lee, S. Ensemble deep learning for skeleton-based action recognition using temporal sliding lstm networks. ICCV, 2017."), we use the proposed RVSML to learn the ground metric and employ the NN classifier to perform classification. We have provided an organized version of the features: https://pan.baidu.com/s/1pY25fGqmKhrSgprc7QynGw

  Dependency:
     vlfeat-0.9.18
     libsvm-3.20

  Usage:
     1. Download the file "MSR_Python_ori.mat" from "https://pan.baidu.com/s/1pY25fGqmKhrSgprc7QynGw" (Extraction code: inrn) and put it under this folder ("MSRAction3D"); 
     2. Add the installation paths of the two packages at the beginning of "EvaluateRVSML_MSRAction3D_60.m" below "TODO: add path"
     3. Run the main code in Matlab:
        EvaluateRVSML_MSRAction3D_60


- ChaLearn --- For the 100-dimensional frame-wide features provided in "https://bitbucket.org/bfernando/videodarwin" (described in "B. Fernando, E. Gavves, J. O. M., A. Ghodrati, and T. Tuytelaars,¡°Modeling video evolution for action recognition,¡± CVPR, 2015."),  we use the proposed RVSML to learn the ground metric and employ the NN classifier to perform classification. We have provided an organized version of the features: https://pan.baidu.com/s/1mjkonfeJMojoUGnMNYpXpw

  Dependency:
     vlfeat-0.9.18
     libsvm-3.20

  Usage:
     1. Download the folder "datamat" from "https://pan.baidu.com/s/1mjkonfeJMojoUGnMNYpXpw" and put it under this folder ("ChaLearn"); 
     2. Add the installation paths of the two packages at the beginning of "EvaluateRVSML.m" below "TODO: add path"
     3. Run the main code in Matlab:
        EvaluateRVSML


- ChaLearn_Deep --- For the 100-dimensional frame-wide features provided in "https://bitbucket.org/bfernando/videodarwin" (described in "B. Fernando, E. Gavves, J. O. M., A. Ghodrati, and T. Tuytelaars,¡°Modeling video evolution for action recognition,¡± CVPR, 2015."),  we use the proposed Deep-RVSML to learn the ground metric and employ the NN classifier to perform classification.

  Dependency:
     vlfeat-0.9.18
     libsvm-3.20
     Python >= 3.5
     PyTorch = 1.0
     The code for the paper "Xun Wang, Xintong Han, Weilin Huang, Dengke Dong, and Matthew R Scott, Multi-Similarity Loss with General Pair Weighting for Deep Metric Learning, CVPR 2019": https://github.com/bnu-wangxun/Deep_Metric

  Usage:
     1. Follow the instructions at https://github.com/bnu-wangxun/Deep_Metric, download the codes to a folder named "Deep_metric-seq-master";
     2. Follow the instructions in "ChaLearn" above to prepare the data and toolboxes, move the .mat files in the downloaded folder "datamat" to the subfolder "datamat/ChaLearn/";
     3. Copy all the folders and codes in this folder "ChaLearn_Deep" to "Deep_metric-seq-master" to overwriting the original files;
     4. Modify all absolute paths in "EvaluateDeepRVSML.m" and other (.py and .m) codes to your custom paths;
     5. Run the main code in Matlab under folder "Deep_metric-seq-master":
        EvaluateDeepRVSML
