A Dynamical Implementation of Self-organizing Maps
The standard learning algorithm for self-organizing maps (SOM) involves the two steps of a search for the best matching neuron and of an update of its weight vectors in the neighborhood of this neuron. In the dy-namical implementation discussed here, a competitive dynamics of laterally coupled neurons with diiusive interaction is used to nd the best-matching neuron. The resulting neuronal excit...
متن کاملSelf Organizing Maps: A Robust Implementation
Methods for visualizing multidimensional data are of great interest in computer science and engineering. One popular technique is selforganizing map, a type of neural network, that uses machine learning algorithms to map multidimensional data to a two-dimensional surface. They are widely used for exploratory data analysis and visualization and have been used to perform clustering and classifica...
متن کاملusing game theory techniques in self-organizing maps training
شبکه خود سازمانده پرکاربردترین شبکه عصبی برای انجام خوشه بندی و کوانتیزه نمودن برداری است. از زمان معرفی این شبکه تاکنون، از این روش در مسائل مختلف در حوزه های گوناگون استفاده و توسعه ها و بهبودهای متعددی برای آن ارائه شده است. شبکه خودسازمانده از تعدادی سلول برای تخمین تابع توزیع الگوهای ورودی در فضای چندبعدی استفاده می کند. احتمال وجود سلول مرده مشکلی اساسی در الگوریتم شبکه خودسازمانده به حسا...
Multi-Dimensional Self-Organizing Maps on Massively Parallel Hardware
Although available (sequential) computer hardware is very powerful nowadays, the implementation of artificial neural networks on massively parallel hardware is still undoubtedly of high interest, not only under an academic point of view. This paper presents an implementation of multi-dimensional Self-Organizing Maps on a scalable SIMD structure of a CNAPS computer with up to 512 parallel proces...
متن کاملImplementation of Kohonen's Self-Organizing Maps on MANTRA I
Reprinted from This paper presents a computer dedicated to neu-ral algorithms. The computational core of the system is a systolic array of dedicated Processing Elements (PEs). This accelerator provides the primitives to implement several widely used neural models, including Kohonen's Self-Organizing Maps (SOMs). This paper concentrates on the problems related to the mapping of the SOM algorithm...
