Selecting appropriate feature extraction method is absolutely one of the most important factors to archive high classification performance in pattern recognition systems. Among different feature extraction methods proposed for pattern recognition, statistical moments seem to be so promising. Whereas theoretical comparison of the moments is too complicated, in this paper, an experimental evaluat...

An inversion of the speech polarity may have a dramatic detrimental effect on the performance of various techniques of speech processing. An automatic method for determining the speech polarity (which is dependent upon the recording setup) is thus required as a preliminary step for ensuring the well-behaviour of such techniques. This paper proposes a new approach of polarity detection relying o...

We have developed a self-organizing shape formation system based on locally interacting agents whose behaviors are inspired by living cells. Given a predefined macroscopic shape, genetic programming is used to find a finite field function that defines the agents’ interactions. By following the gradient of the cumulative field the agents form into a desired shape. It has been seen that the self-...

Articles you may be interested in The Hausdorff entropic moment problem A new method for solving the Hausdorff moment problem is presented which makes use of Pollaczek polynomials. This problem is severely ill posed; a regu-larized solution is obtained without any use of prior knowledge. When the problem is treated in the L* space and the moments are finite in number and affected by noise or ro...
