Teaching Robots to Interpret Social Interactions through Lexically-guided Dynamic Graph Learning

Mathieu Chollet, Tanaya Guha, Tongfei Bian

SocialLDG is a multi-task framework using language models for lexical priors and dynamic graphs to model evolving task affinities among six social interaction tasks, claiming SOTA results on two public HRI datasets plus scalability without forgetting.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

SocialLDG achieves state-of-the-art performance on two challenging human-robot social interaction datasets available publicly. Second, it supports strong task scalability by learning new tasks seamlessly without catastrophic forgetting. Finally, benefiting from explicit modelling task affinity, it offers insights on how different interactions unfolds in time and how the internal states and observable actions influence each other in human decision making.

C2weakest assumption

Our premise is that these states arise from the same underlying socio-cognitive process and influence each other dynamically.
