# Soft Computing

## Membership Functions

A membership function (MF) is a curve that defines how each point in the input space is mapped to a membership value (or degree of membership) between 0 and...

## Fuzzy Set Operations

Definitions. Universe of DiscourseThe Universe of Discourse is the range of all possible values for an input to a fuzzy system. Fuzzy SetA Fuzzy Set is any set that...

## Fuzzy Sets

Fuzzy Set Theory was formalised by Professor Lofti Zadeh at the University of California in 1965. What Zadeh proposed is very much a paradigm shift that first gained acceptance...

## Introduction to Soft Computing

In computer science, soft computing is the use of inexact solutions to computationally hard tasks such as the solution of NP-complete problems, for which there is no known algorithm...

## Hebbian Learning

Hebbian learning is one of the oldest learning algorithms, and is based in large part on the dynamics of biological systems. A synapse between two neurons is strengthened when...

## Learning Vector Quantization

Learning vector quantization (LVQ), is a prototype-based supervised classification algorithm. LVQ is the supervised counterpart of vector quantization systems. LVQ can be understood as a special case of an artificial...

## Simple Competitive Learning Networks

In competitive networks, output units compete for the right to respond. Goal: method of clustering – divide the data into a number of clusters such that the inputs in...

## Kohonen Self Organizing Networks

Kohonen’s networks are one of basic types of self-organizing neural networks. The ability to self-organize provides new possibilities – adaptation to formerly unknown input data. It seems to be...

## Radial Basis Function Network

A Radial Basis Function Network (RBFN) is a particular type of neural network. In this article, I’ll be describing it’s use as a non-linear classifier. Generally, when people talk...

## Adaline Neural Network

ADALINE (Adaptive Linear Neuron or later Adaptive Linear Element) is an early single-layer artificial neural network and the name of the physical device that implemented this network. The network...
