ai for intelligent training

Problem Formulation

Main problem-solving domains such as real-time damage control aboard naval vessels or emergency medical care require a human to make critical decisions in real-time with respect to several simultaneous phenomena. Such domains can be challenging due to the time and resource constraints and stressful due to high costs of making a mistake. Moreover, opportunities for real-life training are often limited as such training can be expensive and dangerous.

Our Contributions

Working in the ship-board damage control domain, we have developed a Petri-Net-based formalism as a rapid machine-learnable domain model whose predictions can be articulated to a trainee. We combined it with a machine-learned evaluator of domain states to predict and evaluate outcomes of a trainee's actions. Integrating these techniques into a blackboard-based problem-solver, we had a system with an expert-level performance and an ability to observe and critique trainee's actions.

On another project we combined an existing computational model for culturally affected behavior (CAB) with a subset of an appraisal-based emotion model (EMA). The resulting model, Culture, EMotion and Adaptation (CEMA), is a light-weight computational engine capable of adding culturally and emotionally affected behaviors to non-playable characters in immersive training systems, with the aim of increasing their believability and, consequentially, their training effectiveness.


Work in Progress

We are presently exploring the application of our player modeling techniques developed for the interactive storytelling and emotion modeling projects to intelligent training. First, we are looking at modeling the trainee's emotion state and using it to dynamically shape a medical training system for neonatal emergency care. Second, we are considering ways to model the student's emotional state and the learning style inclination in a massively open online course (MOOC).
