Learning Action-Effect Dynamics for Hypothetical Vision-Language Reasoning Task
This work addresses the challenge of enabling autonomous agents to reason about actions in visual and linguistic contexts, representing an incremental advancement in vision-language reasoning.
The paper tackles the problem of reasoning about actions and change in vision-language tasks by proposing a novel learning strategy to improve action-effect dynamics, achieving performance gains on the CLEVR_HYP dataset with advantages in data efficiency and generalization.
'Actions' play a vital role in how humans interact with the world. Thus, autonomous agents that would assist us in everyday tasks also require the capability to perform 'Reasoning about Actions & Change' (RAC). This has been an important research direction in Artificial Intelligence (AI) in general, but the study of RAC with visual and linguistic inputs is relatively recent. The CLEVR_HYP (Sampat et. al., 2021) is one such testbed for hypothetical vision-language reasoning with actions as the key focus. In this work, we propose a novel learning strategy that can improve reasoning about the effects of actions. We implement an encoder-decoder architecture to learn the representation of actions as vectors. We combine the aforementioned encoder-decoder architecture with existing modality parsers and a scene graph question answering model to evaluate our proposed system on the CLEVR_HYP dataset. We conduct thorough experiments to demonstrate the effectiveness of our proposed approach and discuss its advantages over previous baselines in terms of performance, data efficiency, and generalization capability.
