I have a question regarding a research article titles "Modeling Individualization in a Bayesian Networks Implementation of Knowledge Tracing". I am trying to create a bayesian network for the model shown in this paper.
As per my understanding there is a parent node called prior knowledge, which has three child nodes namely guess rate, slip rate, and learn rate. These three nodes have a common child called question node which has two states called 'correct' and 'incorrect', depending on whether the answer to question is correct or not.
I have another viewpoint, which relates more to the figure 1 from the article, as shown below. In this view, there are three nodes. Student node, which is specific to a student and governs the prior knowledge parameter. A knowledge node (K) which has two states determining the knowledge/skill is obtained or not. A question node (Q) which again has two states, related to whether the question is answered correctly or not. Transition from K to Q is governed by the guess and slip rates, i.e. even if a student has the knowledge they can slip the question (answer it wrong) and despite being no skill they may answer it correctly (guess correctly).
I am making an educational video game and have no prior practical experience with the Bayesian networks. My game has 5 levels, each level has a quiz in the end. I will ask a question in the beginning of each level to gauge their prior knowledge, so that I do not have to assign a random or same value for the prior knowledge parameter for all the students. I am planning to assign a value of 0.5 to each of the guess, slip and learn rates in the beginning. As the student answers the first question I need to re-adjust the values of the guess, slip and learn rates. I will then use these to adjust the game play to show more or better hints, and basically adjust the game to the level of the student. However, I am stuck right now and despite reading a lot I am not able to figure out how to go about this.
PS: I have made the game in unity and planning to use the infer.net framework for running Bayesian inference.

may be you can ask this at stats.stackexchange.com which seems to be more apt
