Language Model Guided Interpretable Video Action Reasoning

While neural networks have excelled in video action recognition tasks, their “black-box” nature often obscures the understanding of their decision-making processes. Re-cent approaches used inherently interpretable models to an-alyze video actions in a manner akin to human reasoning. These models, however, usually fall short in performance compared to their “black-box” counterparts. In this work, we present a new framework named Language-guided Interpretable Action Recognition framework (La-IAR). LaIAR leverages knowledge from language models to enhance both the recognition capabilities and the inter-pretability of video models. In essence, we redefine the problem of understanding video model decisions as a task of aligning video and language models. Using the logical reasoning captured by the language model, we steer the training of the video model. This integrated approach not only improves the video model's adaptability to different domains but also boosts its overall performance. Extensive experiments on two complex video action datasets, Charades & CAD-120, validates the improved performance and inter-pretability of our LaIAR framework.
