The problem of building a regression tree is considered when the response variable is a probability density function. Splitting criteria which are well adapted to measure the dissimilarity between densities are proposed using the Csiszár’s f-divergence. The comparison between performances of trees constructed with various criteria is tackled through numerical simulations. Afterwards, a tree is ...

This paper outlines an adaptive wavelet-based perceptual audio coding scheme attending to various entropy-type criteria. Its performance using some different wavelet families and various filter lengths and decomposition depths has also been investigated. An optimal choice of these parameters is accomplished in order to evaluate both quality and bit rate of compressed signals for four different ...

PURPOSE To develop clinical prediction models for local regional recurrence (LRR) of breast carcinoma after mastectomy that will be superior to the conventional measures of tumor size and nodal status. METHODS AND MATERIALS Clinical information from 1,010 invasive breast cancer patients who had primary modified radical mastectomy formed the database of the training and testing of clinical pro...

extended abstract 1. introduction currently the study of urban exhausted tissues is one of the major issues in urban policies as well as the contemporary urban planning in iran. lack of attention to exhausted tissues results in the growth of these tissues and the remove of local residents from these areas over time. therefore, the problem of identifying the type of exhausted tissues based on ap...

The genus Trifolium L. belonging to family Fabaceae is represented by about 255 species in the world. Two classifications based on sections or subgenus are commonly used researchers taxonomically evaluation of Trifolium. However, there still some confusing and complex situations taxonomy genus. For this reason, internal transcribed spacer (ITS) regions between rDNA genes nrDNA were examined for...

thought to be variations of a single gene disorder turn out to be genetically diverse with different genetic and!/or clinical implications for a family. The twenty-eight articles in this book discuss as precisely as is now possible the penetrance and variable expression in several kinds of malformation syndromes. The broad, well-organized range of subjects includes syndromes involving primarily...

The neurocontroller of the pasteurization machine was developed. It consists of two parts: the neuroemulator and the serial neurocontroller, which are based on the multilayer perceptron structure. The neurocontroller has been implemented as a module in the SCADA-system at OJSC “Savushkin product” and has a good effect in comparison with the conventional PID controller. Testing showed the effect...
