An accelerator for Kohonen Self-Organizing Maps
In this work we are describing hardware implementation of Kohonen SelfOrganizing Map. We examined existing neurocomputers and decided to work out our own neurocomputer with a different, more suitable architecture. Our neurocomputer is being realized on FPGA (Field-Programmable Gate Array). In this article we are describing basic neurocomputer unit structure as well as linkage of these elements ...
متن کاملTopographic Maps Based on Kohonen Self Organizing Maps An Empirical Approach
Two-dimensional maps are a valuable interface element for the visualization of information retrieval results or other large sets of objects. Various methods exist for the creation of these maps. This article describes a comparative evaluation of topographic maps based on “Kohonen Self Organizing Maps” (SOM). These results show that the mapping method has to be chosen very carefully and differen...

متن کاملGeneralized Winner-Relaxing Kohonen Self-Organizing Feature Maps
We calculate analytically the magnification behaviour of a generalized family of self-organizing feature maps inspired by a variant introduced by Kohonen in 1991, denoted here as Winner Relaxing Kohonen algorithm, which is shown here to have a magnification exponent of 4/7. Motivated by the observation that a modification of the learning rule for the winner neuron influences the magnification l...
متن کاملMolecular subtyping of bladder cancer using Kohonen self-organizing maps
Kohonen self-organizing maps (SOMs) are unsupervised Artificial Neural Networks (ANNs) that are good for low-density data visualization. They easily deal with complex and nonlinear relationships between variables. We evaluated molecular events that characterize high- and low-grade BC pathways in the tumors from 104 patients. We compared the ability of statistical clustering with a SOM to strati...
