Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose a method based on supervised contrastive learning in order to extract better feature for action detection. Action detection is still difficult and some actions are hard to detect. While actions related to actors' pose are easy to classify, those related to interactions with surroundings are not. Since the difficulty is partly caused by the variation of the actions, we propose a method for better feature extraction. By comparing with a standard supervised method, we show that the accuracy in some difficult labels has improved.
