Exploring the Role of Common Model of Cognition in Designing Adaptive Coaching Interactions for Health Behavior Change

no code implementations17 Oct 2019 Shiwali Mohan

We leverage the common model of cognition - CMC [26] - as a framework for unifying several behavior change theories that are known to be useful in human-human coaching.

Designing an AI Health Coach and Studying its Utility in Promoting Regular Aerobic Exercise

no code implementations10 Oct 2019 Shiwali Mohan, Anusha Venkatakrishnan, Andrea Hartzler

We show that our approach can adapt the trainee program not only to several trainees with different capabilities, but also to how a trainee's capability improves as they begin to exercise more.

Acceptable Planning: Influencing Individual Behavior to Reduce Transportation Energy Expenditure of a City

no code implementations23 Sep 2019 Shiwali Mohan, Hesham Rakha, Matthew Klenk

Our research aims at developing intelligent systems to reduce the transportation-related energy expenditure of a large city by influencing individual behavior.

A Computational Model for Situated Task Learning with Interactive Instruction

no code implementations23 Apr 2016 Shiwali Mohan, James Kirk, John Laird

Learning novel tasks is a complex cognitive activity requiring the learner to acquire diverse declarative and procedural knowledge.

Towards an Indexical Model of Situated Language Comprehension for Cognitive Agents in Physical Worlds

no code implementations9 Apr 2016 Shiwali Mohan, Aaron Mininger, John Laird

We propose a computational model of situated language comprehension based on the Indexical Hypothesis that generates meaning representations by translating amodal linguistic symbols to modal representations of beliefs, knowledge, and experience external to the linguistic system.
