A new feature extraction method based on multidirectional correlation function is proposed for improving the classification performance of halftone images in this paper. The correlation function is improved to obtain feature vectors on three directions of halftone images. Based on the definition of pixel probability, pixel entropy and entropy histogram, we introduce a decision rule to reject so...

Nearest neighbor classification expects the class conditional probabilities to be locally constant. The assumption becomes invalid in high dimension due to the curse−of−dimensionality. Severe bias can be introduced under this condition when using nearest neighbor rule. We propose an adaptive nearest neighbor classification method ¡°indecisive classifier¡± to minimize bias and variance by avoidi...

Concurrence looks at how a measure relates to a gold standard. If, as frequently occurs, there isn’t one, the next best is the correlation with other established measures. This assumes that the latter are themselves valid, which may not be true, and risks stifling innovation, a source of concern if a paper is criticized on this ground. More straightforwardly, concurrence also means that a test ...

In Prior Analytics 1.15 Aristotle undertakes to establish certain modal syllogisms of the form XQM. Although these syllogisms are central to his modal system, the proofs he offers for them are problematic. The precise structure of these proofs is disputed, and it is often thought that they are invalid. We propose an interpretation which resolves the main difficulties with them: the proofs are v...

In this cand.scient. thesis we propose a strategy for testing validity of decomposition of contract oriented specifications. The strategy is based on Abadi and Lamport’s Composition Theorem for the Temporal Logic of Actions and test case generation from executable specifications. A composition rule, inspired by the Compositon Theorem, is formulated in a semantics based on timed streams. A subse...

The synergetic effects of dietary obesity and stress induced by electrical shocks on insulin secretion from the perfused pancreas, the action of insulin on adipose tissues and glucose tolerance were studied in rats. The rat was fed either a control (C) (50% starch) or a high fat diet (F) (40% butter) for a period of 12 weeks. Half of the rats on each diet received electrical shocks, one hour pe...

Many methods for automatic and semi-automatic ontology alignment have been proposed, but they remain error prone and laborintensive. This paper describes a novel generic process for evaluating the mappings’ confidence value. This process uses rules extracted through inductive machine learning methods from the matching results proposed by others. Further, the precision and recall of the extracte...

In many practical parameter estimation problems, a model selection is made prior to estimation. In this paper, we consider the problem of estimating an unknown parameter of a selected population, where the population is chosen from a population set by using a predetermined selection rule. Since the selection step may have an important impact on subsequent estimation, ignoring it could lead to b...
