Abstract:

A system includes a virtual reality system configured to enable a user to interact with a virtual environment, a plurality of biofeedback sensors configured to monitor a user, and a computer system including a virtual reality module configured to generate at least a view of the virtual environment, a biofeedback module configured to fuse output of the plurality of biofeedback sensors with a plurality of events within the virtual environment, a training module configured to generate a model of user behavior, wherein the training module executed by the computer system enables the computer system to make a prediction of a user response of the user based on a corpus of biofeedback data, and an alert module configured to generate at least one alert to the user via the virtual reality system based on the user response predicted by the computer system.

Abstract:

Systems, methods, and computer-readable media are described for determining a score for a target student answer using unlabeled data. The target answer is provided by a student to a question for which there is no ground-truth answer data. A set of student answers serves as a set of pseudo-reference answers and a classifier is used to score each answer based on each other answer. In this manner, each student answer serves as a pseudo-reference answer for each other student answer. A clustering approach can also be employed to cluster a set of student answers into clusters. The centroids of the clusters can then serve as the set of pseudo-reference answers. Clustering improves the robustness and efficiency of the score determined for a target student answer.

International Classification:

G09B 7/02

Abstract:

A method and system of interactive tutoring is provided. A question is sent to a user device. Upon determining that the response does not correspond to a known correct answer, a concept map is identified and a cost function between the correct answer and the response is determined. Upon determining that the cost function between the correct answer and the response is above a predetermined threshold, the question is identified to be the origin. Otherwise, the response is identified to be the origin. A present academic proficiency of the student is determined. A difficulty boundary based on the academic proficiency of the student is determined. A next question is provided between the origin and the correct answer, based on the determined difficulty boundary of the student.
