To run this code, first install Torch7, then install csvigo by using luarocks (luarocks install csvigo).

To test the method on NTU RGB+D dataset, please put the files "skl.csv", "descs.csv", and "training_testing_subjects.csv" in the folder "/data/".

• "skl.csv" needs to include all the frames of all video samples. The row number is the frame number. The column number is 3x25x2, i.e., x1, y1, z1, x2, y2, z2...

• "descs.csv" is a description to index the frames strored in "skl.csv". The column number is the video sample number. The row index is respectively subject id, camera id, setup id, duplicate id, action id, starting frame id, and ending frame id.

• "training_testing_subjects.csv" is the split of the train/test subjects for the NTU RGB+D dataset.
