Hi @luckcodingdog , I'm not sure if I understand your question correctly. The short-term feature and the long-term features are connected through FBO (implemented in https://github.com/facebookresearch/video-long-term-feature-banks/blob/master/lib/models/lfb_helper.py). Could you please explain what you want to make sure again?
