One of the central problems in the eld of knowledge discovery is the development of good measures of in terestingness of discovered patterns Such measures of interestingness are divided into objectivemeasures those that depend only on the structure of a pat tern and the underlying data used in the discovery process and the subjective measures those that also depend on the class of users who exa...

Adding examples of the majority class to the training set can have a detrimental eeect on the learner's behavior: noisy or otherwise unreliable examples from the majority class can overwhelm the minority class. The paper discusses criteria to evaluate the utility of clas-siiers induced from such imbalanced training sets, gives explanation of the poor behavior of some learners under these circum...

Abstract -This paper presents an architecture for a high-speed carry select adder with very long bit lengths utilizing a conflict-free bypass scheme. The proposed scheme has almost half the number of transistors and is faster than a conventional carry select adder. A comparative study is also made between the proposed adder and a Manchester carry chain adder which shows that the proposed scheme...

Most approaches to the ramiication problem are based on the principle of minimization of change. It turns out, however, that this principle can not be applied uniformly, and many modern approaches use a clas-siication of the uents whereby change is only minimized in some of the uents. The present article reviews these approaches and their underlying motivations. It also presents a uniied formal...

Twenty-four general-practice trainees were assessed at the beginning and end of their training year. They improved significantly in their factual recall and problem-solving ability. Sixteen young principals who had had an unstructured training for general practice were assessed at the same time and were initially of the same standard but their results showed no difference over the same year.
