Selecting a set of features which is optimal for a given task is a problem which plays an important role in a wide variety of contexts including pattern recognition, adaptive control, and machine learning. Our experience with traditional feature selection algorithms in the domain of machine learning lead to an appreciation for their computational efficiency and a concern for their brittleness. ...

Correlational selection favors combinations of traits and is a key element of many models of phenotypic and genetic evolution. Multiple regression techniques for measuring selection allow for the direct estimation of correlational selection gradients, yet few studies in natural populations have investigated this process. Color patterns and antipredator behaviors of snakes are thought to functio...

This survey compares internal representations of the recent as well as more traditional face recognition techniques to classify them into several broad categories. The categories assessed include template matching and feature measurements, analysis of global and local facial features, and incorporation of interpersonal and intrapersonal variations of human faces. Analysis of the face recognitio...

Comparisons of rhythmic movements and the central pattern generators (CPGs) that control them uncover principles about the evolution of behaviour and neural circuits. Over the course of evolutionary history, gradual evolution of behaviours and their neural circuitry within any lineage of animals has been a predominant occurrence. Small changes in gene regulation can lead to divergence of circui...

-The automatic recognition of printed Farsi (Persian) texts is complicated by several properties of the Farsi script: (a) connectivity of symbols, (b) similarity of groups of symbols, (c) highly variable widths, (d) subword overlap, and (e) line overlap. In this paper, a technique for the automatic recognition of printed Farsi texts is presented and its steps are discussed as follows : (1) digi...

OBJECTIVE To review theories and technologies of big data mining and their application in clinical medicine. DATA SOURCES Literatures published in English or Chinese regarding theories and technologies of big data mining and the concrete applications of data mining technology in clinical medicine were obtained from PubMed and Chinese Hospital Knowledge Database from 1975 to 2015. STUDY SELE...

We have introduced two crossover operators, MMX-BLX and MMX-BLX, for simultaneously solving multiple feature/subset selection problems where the features may have numeric attributes and the subset sizes are not predefined. These operators differ on the level of exploration and exploitation they perform; one is designed to produce convergence controlled mutation and the other exhibits a quasi-co...

A simple yet powerful technique for selecting features to be used in a pattern recognition system has been devised and applied to an eight-class character recognition problem using a set of 19 000 typed character samples as a data base. High-order joint probabilities have been directly estimated from the data base, thus making it possible to take into account in the feature selection process th...

OBJECTIVE To report on the current state of research analyzing early father-infant bonding, including influential factors and interventions, to identify gaps in the literature. DATA SOURCES CINAHL, MEDLINE, PubMed, and PsychInfo computerized databases were searched using the keywords bonding, paternal, father, infant, relationship, engrossment, and postpartum. STUDY SELECTION Twenty-eight a...
