Probabilistic assessment of user's emotions in educational games
TL;DR: The probabilistic model presented is to be used by decision theoretic pedagogical agents to generate interventions aimed at achieving the best tradeoff between a user's learning and engagement during the interaction with educational games.
Journal ArticleDOI
Using Bayesian Networks to Manage Uncertainty in Student Modeling
TL;DR: The basic mechanisms that allow Andes’ student models to soundly perform assessment and plan recognition, as well as the Bayesian network solutions to issues that arose in scaling up the model to a full-scale, field evaluated application are described.
Journal ArticleDOI
Empirically building and evaluating a probabilistic model of user affect
Cristina Conati,Heather Maclaren +1 more
TL;DR: This paper illustrates how the predictive part of the affective model is built by combining general theories with empirical studies to adapt the theories to the target application domain and presents results on the model’s accuracy, showing that the model achieves good accuracy on several of the target emotions.
Proceedings Article
Toward Computer-Based Support of Meta-Cognitive Skills: a Computational Framework to Coach Self-Explanation
Cristina Conati,Kurt VanLehn +1 more
TL;DR: A computational framework designed to improve learning from examples by supporting self-explanation o the process of clarifying and making more complete to oneself the solution of an example, which is first attempt to provide computer support to example studying instead of problem solving.
Book ChapterDOI
On-Line Student Modeling for Coached Problem Solving Using Bayesian Networks
TL;DR: The knowledge structures represented in the student model are described and the implementation of the Bayesian network assessor is discussed, and a preliminary evaluation of the time performance of stochastic sampling algorithms to update the network is presented.
