Structure-Mapping-Guided Self-Explanation for Learning Mathematical Procedures

A structure-mapping-guided self-explanation as a computational account of the cognitive biases that reduce search effort and make this inference tractable and a testable hypothesis about human self-explanation from worked examples are proposed.

SMTB: Fast Structure-Mapping with Tight Bounds

A new structure-mapping algorithm: SMTB that is 5--15x faster than the structure-mapping engine (SME) and about 50\% better at finding mappings in large nested domains and an evaluation comparing SMTB to SME v4 over 5845 domain pairs from the SME corpus.

When Should Users Check? Modeling Confirmation Frequency in Multi-Step Agentic AI Tasks

A decision-theoretic model is developed to determine time-efficient confirmation point placement and results show that 81% of participants preferred the intermediate confirmation approach over the confirm-at-end approach used by existing systems, and task completion time was reduced by 13.54%.
