[Show abstract][Hide abstract] ABSTRACT: Decision tree is an important method for both induction research and data mining, which is mainly used for model classification and prediction. ID3 algorithm is the most widely used algorithm in the decision tree so far. Through illustrating on the basic ideas of decision tree in data mining, in this paper, the shortcoming of ID3's inclining to choose attributes with many values is discussed, and then a new decision tree algorithm combining ID3 and association function(AF) is presented. The experiment results show that the proposed algorithm can overcome ID3's shortcoming effectively and get more reasonable and effective rules.
[Show abstract][Hide abstract] ABSTRACT: Based on one complex SOC chip, one functional enhancement methodology to standard IEEE P1149.1 JTAG controller is proposed in this paper. With the enhanced features, all test functions including stuck-at scan, at-speed scan, memory BIST and high-speed physical layer tests can be controlled by the JTAG controller besides traditional boundary scan tests, and further on-chip debug features are also integrated in this enhanced JTAG controller. Therefore, the chip costs can be reduced, and the software development and debug can be facilitated with the enhanced JTAG controller.
