Summary of Computer doctoral thesis: Mining decision laws on the data block

The objective of the thesis focus on solving three problems: To find decision laws on the data block and block’s slice; to find decision laws bettwen object groups on the block which has index attribute value change, particulary when smoothing, or roughing attribute value; to find decision laws bettwen object groups on the block when adding or removing block’s elements. | MINISTRY OF EDUCATION AND VIETNAM ACADEMY TRAINING OF SCIENCE AND TECHNOLOGY GRADUATE UNIVERSITY SCIENCE AND TECHNOLOGY ------------------------------ Do Thi Lan Anh MINING DECISION LAWS ON THE DATA BLOCK Major Computer sciense Code 9 48 01 01 SUMMARY OF COMPUTER DOCTORAL THESIS Ha Noi 2020 The thesis was completed at Graduate University of Science and Technology - Vietnam Academy of Science and Technology Science instructor Assoc.

The urgency of the thesis Mining decision laws is the process of defining decision laws on a given decision table serving the object classification problem. This is one of the popular data mining techniques and has been studied by many domestic and foreign experts on both of the relational model and the extended models of the relational model. Researches in the world and our country for the purpose of finding meaningful knowledge especialy the laws on different data models with different research directions. An approach to the data block model of the authors with the purpose of tracking the laws occurring in a process that changes over time period . is the desire to contribute of the thesis. 2. The objective of the thesis The objective of the thesis focus on solving three problems - To find decision laws on the data block and block s slice. - To find decision laws bettwen object groups on the block which has index attribute value change particulary when smoothing or roughing attribute value. - To find decision laws bettwen object groups .
