Journal ArticleDOI
A discretization algorithm based on Class-Attribute Contingency Coefficient
TL;DR: Empirical evaluation showed that the proposed algorithm could generate a better discretization scheme that improved the accuracy of classification and the execution time, number of generated rules, and the training time of C5.0.
Journal ArticleDOI
Ontology technology to assist learners' navigation in the concept map learning system
TL;DR: A concept map learning system with ontology technology to help users search the concept map, determine relationships between nodes or predicates, and find the common concept or predicate among the concepts to help reduce the user's cognitive load is implemented.
Journal ArticleDOI
Mining decision rules on data streams in the presence of concept drifts
TL;DR: A method that should classification models be required, can efficiently and accurately generate such models via a simple extraction procedure rather than constructing them anew, and two strategies to reduce the complexity of concept-drifting rules mined by the CDR-Tree are proposed.
Journal ArticleDOI
An Appropriate Prompts System Based on the Polya Method for Mathematical Problem-Solving
TL;DR: This study investigated the influences of a teaching activity incorporating Polya’s method and an appropriate prompt mechanism on the learning effectiveness of students and showed that there were significant differences between the experimental group and the control group in thelearning effectiveness.
Journal ArticleDOI
An approach to mining the multi-relational imbalanced database
TL;DR: A multi- Relational g-mean decision tree algorithm to solve the imbalanced problem in a multi-relational database is proposed and can more accurately mine a multi -relational imbalanced database.
