Skill estimation device, learning support device, skill estimation method and program

摘要

The skill estimation device includes a correctness/accuracy data acquisition unit that acquires correctness/incorrectness data indicating the correctness/incorrectness of the answer that the learner solved the problem as binary data, the skill required to solve the problem, and the learner's possession. It is necessary to solve the problem by searching for a solution that maximizes the posterior probability based on the correct/wrong data, using a model in which each skill is represented by a binary random variable that indicates the presence or absence of the skill. Skills, and a skill estimation unit that estimates the skills held by the learner.
