Reinforcement Explanation Learning
Siddhant Agarwal, Owais Iqbal, Sree Aditya Buridi, Mada Manjusha, Abir Das
35th Conference on Neural Information Processing Systems (NeurIPS), 2021.

arXiv /
code
We reformulate the process of generating saliency maps using perturbation based methods for black box models as a Markov Decsion Process and use RL to optimally search for the best saliency map, thereby reducing the inference time without hurting the performance.

Semi-Supervised Action Recognition with Temporal Contrastive Learning
Ankit Singh, Omprakash Chakraborty, Ashutosh Varshney, Rameswar Panda, Rogerio Feris, Kate Saenko, Abir Das
Computer Vision and Pattern Recognition (CVPR), 2021.
project page /
poster /
video presentation /
code
We address semi-supervised video action recognition by learning a two-pathway temporal contrastive model where the similarity between representations of the same video at two different speeds are maximized while the similarity between different videos played at different speeds are minimized.
