This is the 3rd Workshop on Self-Organising Maps (WSOM) and its similar ideas. the former have been held in Helsinki (1997 and 1999) and proven the energy of the SOM as some of the most well known and strong suggestions for unsupervised trend attractiveness and information visualisation. those conferences not just acted as a exhibit for the most recent advances in SOM thought and for illustrating its giant variety of applicability, but in addition as venues the place a lot casual and fruitful interplay may occur. it really is attention-grabbing to monitor the advance of the unique SOM, and this outstanding development confrrms the originality and perception of Teuvo Kohonen's pioneering paintings. With the diversity and caliber of the papers during this quantity, the level is decided for an additional very winning assembly. This quantity is an everlasting checklist of all of the contributions awarded in the course of WSOM'OI held on the college of Lincolnshire and Humberside, thirteen - 15 June, 2001. The collage is the most recent of England's universities however it is positioned within the middle of 1 of our oldest towns - based through the Romans and ignored through the towering mass of its medieval cathedral. basically Lincoln has continuously been a centre for the wealthy agricultural heartland of britain; besides the fact that, it used to be the birthplace, 186 years in the past, of George Boole. So WSOM'OI is constant Lincoln's lengthy and honourable culture of advancing clinical understanding.

Mechanisms of Lymphocyte Activation and Immune Regulation II

The ac ti vati on of Iymphocytes via physiologie ligands has develop into a principal zone of analysis for immunologists. additionally, Iymphocytes provide many merits for the examine of basic elements of receptor-mediated mobile activation. For those purposes, learn at the mobile and molecular facets of the activation of Iymphocytes by means of antigens, antigen analogues, Iymphokines and different progress components has improved significantly within the final numerous years.

Nq], is realized through a q dimensional lattice of neurons 3 . Thus, the winning neuron is represented by the coordinates (i 1 , '" i q ). nd x .. nlJ x .. n q], and the m + cq dimensional input vector v to senting the information about a generic node v, is defined as v = [u v Nt, repre- Vchdv] V Ch2 [v] ... VChc[v]] , where Vchdv] denotes the coordinates vector 4 of the winning neuron for the subgraph pointed by the i-th pointer of v. Each neuron with coordinates vector Cj in the q dimensional lattice has an associated vector weight wc, E IRm+cq.

3 % (see (1]). The economic literature suggests many ways, in which the real effects caused by speculative attacks may be amplified by specific characteristics of the economic environment at the onset of the crisis or by government policies in the aftermath. The banking system may amplify output effects as exchange rate shocks can also trigger credit crunches. Poor creditor's protection may cause capital outflows in the aftermath of the crisis that would reduce the current account deficit causing further contractions in aggregate demand.

The analysis of motion trajectories is done by combining the wavelet transform for feature extraction and a Kohonen self-organising map (SOM) for classification of walking patterns. Rules are then extracted from the SOM after self-organisation to determine the salient features characterising each cluster as well as differentiating it from others. It is shown and experimentally verified that salient features do exist within the internal structure of the kinematic data from which diagnostic signatures are elicited.
