Abstract Spatial-Temporal Reasoning via Probabilistic Abduction and Execution

Zhang, Chi, Jia, Baoxiong, Zhu, Song-Chun et al.

Understand

Spatial-temporal reasoning is a challenging task in Artificial Intelligence (AI) due to its demanding but unique nature: a theoretic requirement on representing and reasoning based on spatial-temporal knowledge in mind, and an applied requirement on a high-level cognitive system capable of navigating and acting in space and time.

  • Recent works have focused on an abstract reasoning task of this kind -- Raven's Progressive Matrices (RPM).
  • Despite the encouraging progress on RPM that achieves human-level performance in terms of accuracy, modern approaches have neither a treatment of human-like reasoning on generalization, nor a potential to generate answers.
  • To fill in this gap, we propose a neuro-symbolic Probabilistic Abduction and Execution (PrAE) learner; central to the PrAE learner is the process of probabilistic abduction and execution on a probabilistic scene representation, akin to the mental manipulation of objects.
