RelViT: Concept-guided Vision Transformer for Visual Relational Reasoning

Ma, Xiaojian, Nie, Weili, Yu, Zhiding et al.

Understand

Reasoning about visual relationships is central to how humans interpret the visual world.

  • This task remains challenging for current deep learning algorithms since it requires addressing three key technical problems jointly: 1) identifying object entities and their properties, 2) inferring semantic relations between pairs of entities, and 3) generalizing to novel object-relation combinations, i.e., systematic generalization.
  • In this work, we use vision transformers (ViTs) as our base model for visual reasoning and make better use of concepts defined as object entities and their relations to improve the reasoning ability of ViTs.
  • Specifically, we introduce a novel concept-feature dictionary to allow flexible image feature retrieval at training time with concept keys.
