A Parallel Self-Organizing Map (Parallel-SOM) is proposed to modify Kohonen's SOM in parallel computing environment. In this model, two separate layers of neurons are connected together. The contributions in this book cover a range of topics, including parallel computing, parallel processing in biological neural systems, simulators for artificial neural networks, neural networks for visual and auditory pattern recognition as well as for motor control, AI, and examples of optical and molecular computing. The book may be regarded as a state-of-the-art report and at the same.

Abstract. This chapter focuses on parallel implementations of the Self-Organizing Map (SOM) featuring different levels of parallelism. The basic arithmetic-logical operations of SOM are first reviewed for a consideration of implementation issues such as number precision, memory consumption and time Cited by:

Introduction. Presented in the early s by Kohonen, the self-organizing map (SOM) is one of the common approaches on how to represent and visualize data and how to map the original dimensionality and architecture of the input space onto another, usually lower dimensional, architecture in the output Section , we give a brief overview of classical SOMs and their design ideas Cited by: The term “parallel distributed processing” (PDP) is not widely used in the ANN field, for instance. The two remaining PDP books, both titled Explorations in parallel distributed processing: a handbook of models, programs, and exercises, are manuals for the software that accompanies the original two-volume PDP set—one for DOS (two Competitive learning is a form of unsupervised learning in artificial neural networks, in which nodes compete for the right to respond to a subset of the input data. A variant of Hebbian learning, competitive learning works by increasing the specialization of each node in the is well suited to finding clusters within data.. Models and algorithms based on the principle of competitive.
This paper describes the implementation of a neural paradigm, the Kohonen's self organizing Map, on the SMART neurocomputer. This algorithm has been chosen as a test for the capabilities of the architecture. A high level interactive graphic monitor and a basic neural library have been developed, and the performance of the whole system by: 2. Artificial Neural Network ANN is an efficient computing system whose central theme is borrowed from the analogy of biological neural networks. ANNs are also named as “artificial neural systems,” or “parallel distributed processing systems,” or “connectionist systems.” ANN acquires a large collection of units that are interconnected. Model of Artificial Neural Network The following diagram represents the general model of ANN followed by its processing. For the above general model of artificial neural network, the net input can be calculated as follows: y in = x 1.w 1 +x 2.w 2 +x 3.w 3 + + x m.w m i.e., Net input 𝑖 =∑ 𝑖. 𝑖 𝑖File Size: KB.
