Inferring Implicit Goals Across Differing Task Models

AAAI 2026technical

One of the significant challenges to generating value-aligned behavior is to not only account for the specified user objectives but also any implicit or unspecified user requirements. The existence of such implicit requirements could be particularly common in settings where the user

On Generating Monolithic and Model Reconciling Explanations in Probabilistic Scenarios (Abstract Reprint)

AAAI 2026technical

Explanation generation frameworks aim to make AI systems’ decisions transparent and understandable to human users. However, generating explanations in uncertain environments characterized by incomplete information and probabilistic models remains a significant challenge. In this paper, we propose a

Does Your AI Agent Get You? A Personalizable Framework for Approximating Human Models from Argumentation-based Dialogue Traces

AAAI 2025technical

Explainable AI is increasingly employing argumentation methods to facilitate interactive explanations between AI agents and human users. While existing approaches typically rely on predetermined human user models, there remains a critical gap in dynamically learning and updating these models during…

Model Reconciliation via Cost-Optimal Explanations in Probabilistic Logic Programming

NeurIPS 2025poster

In human-AI interaction, effective communication relies on aligning the AI agent’s model with the human user’s mental model -- a process known as model reconciliation. However, existing model reconciliation approaches predominantly assume deterministic models, overlooking the fact that human knowled…

TRACE-CS: A Synergistic Approach to Explainable Course Scheduling Using LLMs and Logic

AAAI 2025technical

We present TRACE-cs, a novel hybrid system that combines symbolic reasoning with large language models (LLMs) to address contrastive queries in scheduling problems. TRACE-cs leverages SAT solving techniques to encode scheduling constraints and generate explanations for user queries, while utilizing…

A Logic-based Explanation Generation Framework for Classical and Hybrid Planning Problems (Extended Abstract)

IJCAI 2023poster

In human-aware planning systems, a planning agent might need to explain its plan to a human user when that plan appears to be non-feasible or sub-optimal. A popular approach, called model reconciliation, has been proposed as a way to bring the model of the human user closer to the agent's model. In…

On Exploiting Hitting Sets for Model Reconciliation

AAAI 2021technical

In human-aware planning, a planning agent may need to provide an explanation to a human user on why its plan is optimal. A popular approach to do this is called model reconciliation, where the agent tries to reconcile the differences in its model and the human's model such that the plan is also opti…
