Desperately Seeking Subscripts: Towards Automated Model Parameterization
نویسندگان
چکیده
This paper addresses the laborious task of specifying parameters within a given model of student learning. For example, should the model treat the probability of forgetting a skill as a theory-determined constant? As a single empirical parameter to fit to data? As a separate parameter for each student, or for each skill? We propose a generic framework to represent and mechanize this decision process as a heuristic search through a space of alternative parameterizations. Even partial automation of this search could ease researchers’ burden of developing models by hand. To test the framework’s generality, we apply it to two modeling formalisms – a dynamic Bayes net and learning decomposition – and compare how well they model the growth of children’s oral reading fluency.

متن کاملA Parameterization Model for Transportation Feature Extraction
This article presents one solution to the parameterization problem for automated road feature extraction models. Using a line-length buffer approach, a measure of agreement between extracted road features and reference road features is defined. An automated approach for deriving this agreement index is presented and implemented as a parameterization model. Coupling the implemented parameterizat...
