The data distribution issue remains an unsolved clustering problem in mining, especially dealing with imbalanced datasets. Kohonen Self-Organising Map (KSOM) is one of the well-known algorithms that can solve various problems without a pre- defined number clusters. However, similar to other algorithms, this algorithm requires sufficient for its unsupervised learning process. inadequate amount c...

The extraction of road networks from digital imagery is a fundamental image analysis operation. Common problems encountered in automated road extraction include high sensitivity to typical scene clutter in high-resolution imagery, and Ž . Ž . inefficiency to meaningfully exploit multispectral imagery MSI . With a ground sample distance GSD of less than 2 m per pixel, roads can be broadly descri...

We construct a benchmarking model in the form of a twodimensional self-organising map (SOM) to compare the performance of nonbanking financial institutions (NFIs) in Romania. The NFIs are characterized by a number of performance dimensions such as capital adequacy, assets’ quality and profitability. First, we apply Kohonen’ SOM algorithm (an unsupervised neural network algorithm) to group the N...

In this paper we review the aim of the INTER 1-project (Intelligent Neural InTERface), especially from the point of view of Artiicial Neural Nets (ANN). We also propose a modus operandi to process real nerve signals using ANN. Finally we present rst experiences using this proposal. Microfabricated neural interfaces promise to become a powerful tool for applications like the control of motor/sen...

Objectives The objective of this chapter is to introduce the subject of selforganising software systems. When you will have read this chapter, you will: • Know the answers to key introductory questions to self-organising systems; • Understand what self-organising software is and why it is important; • Obtain an understanding of different self-organising system types that can be found in nature;...

This article opens a Special Issue on Democratic Stress. Against the background of recent debates ‘democratic crisis’, we argue that concept stress’ provides useful way to understand diversity pressures representative democracy faces in contemporary context, as well valuable ‘organising perspective’ for developing more nuanced analyses. We then map out main contributions articles included this ...

The primary somatosensory cortex contains a topographic map of the body surface, with two notable discontinuities — the representation of the face is next to that of the hands, and that of the feet is next to the genitals. Farah (1998) has suggested that these discontinuities are due to the mechanisms of self-organisation which underlie cortical map development. The typical position of the foet...
