Working repository for feature analysis of 2SCNN

• CUHK VGG16-2SCNN models trained on UCF101
• UoB VGG16-2SCNN trained on BEOID (not publicly available)

• Python 3
  • matplotlib
  • numpy
  • scipy
  • pandas
  • seaborn
  • click
  • skimage
• Jupyter notebook (6.0)
• IPykernel for Jupyter (5.0)
• Bash
• Caffe (Excitation BP fork), preferably built with GPU support.

• Edit lib/config.py to point to your local excitation bp caffe installation, nets path (e.g. caffe/models, I like to keep mine in my home directory), and data root.

• lib: Most of the meaty code lives in here, code for handling datasets, performing contrastive EBP, mapping from class ids to class names.
• net_configs: Python library of configuration scripts defining settings peculiar to models.
• scripts: Python CLI scripts for generating attention maps, stitching videos, graphing smoothness
• generated: A few bash scripts live in here to call the python scripts that do most of the work.
• notebooks: All the Jupyter notebooks used for experimental analysis reside here. They're meant to be run in numerical order. Notebooks with the same numerical prefix can be run in any order.
• ./run_jupyter.sh is a helper script to setup my environment with the correct LD_LIBRARY_PATH and PATH env variables necessary to find Caffe, CuDNN etc.

The code for performing contrastive excitation backprop is from https://github.com/jimmie33/Caffe-ExcitationBP, I also took inspiration from the code used to overlay attention maps on images.
