Mind the Perspective: Let's Reason Recursively for Theory of Mind

Chao Lei, Guang Hu, Meng Yang +2

Theory of Mind (ToM) reasoning requires inferring agents' beliefs from partial and asymmetric observations, which remains an open challenge for LLMs. Existing prompting-based appro…

Beyond Perception: Evaluating Abstract Visual Reasoning through Multi-Stage Task

Yanbei Jiang, Yihao Ding, Chao Lei +3

Current Multimodal Large Language Models (MLLMs) excel in general visual reasoning but remain underexplored in Abstract Visual Reasoning (AVR), which demands higher-order reasoning…
