This paper describes a data organization system and genuine content-addressable memory
called the WEBSOM. It is a two-layer self-organizing map (SOM) architecture where …

The repetitive stochastic patterns of eye dominance and orientation preference found in the
mammalian visual cortex have attracted much attention from theoretical neurobiologists …

Though mathematical ideas underpin the study of neural networks, the author presents the
fundamentals without the full mathematical apparatus. All aspects of the field are tackled …

How are our brains functionally organized to achieve adaptive behavior in a changing
world? This article presents one alternative to the computer analogy that suggests brains are …

A neural network algorithm based on a soft-max adaptation rule is presented. This algorithm
exhibits good performance in reaching the optimum minimization of a cost function for vector …

THE mammalian cortex is organized in a columnar fashion: neurons lying below each other
from the pia to the white matter usually share many functional properties. Across the cortical …

The human ventral visual stream has a highly systematic organization of object information,
but the causal pressures driving these topographic motifs are highly debated. Here, we use …

We investigate the convergence properties of the self-organizing feature map algorithm for a
simple, but very instructive case: the formation of a topographic representation of the unit …

Neighborhood preservation from input space to output space is an essential element of
selforganizing feature maps like the Kohonen-map. However, a measure for the …

Neurons in the primary visual cortex of higher mammals respond selectively to light/dark
borders of a particular orientation. The receptive fields of simple cells, a type of orientation …
