proportional to the product of the error signal and the input
signal of the synapse”. The delta rule assumes that the error
signal is directly measurable. The aim of the delta rule is to
minimize the error over training patterns. Delta rule can be
applied for single output unit and several output units. In
this learning, the output neural network complete among
themselves to become active. The basic idea behind this rule
is that there are a set of neurons that are similar in all
aspects excepts for some randomly distributed synaptic
weights, and therefore respond differently to a given set of
input patterns. However, a limit is imposed on the strength
of the neurons. This rule has a mechanism that permit the
neuron to complete of the right to respond to a given subset
of inputs, such that only one output neuron, or only one
neuron per group, is active at a time. The winner neuron
during competition is called winner-takes-all neuron.
2.1. Applications of Artificial Neural Network
Neural Network in arts: The rapidly expanding field of
neural networks provides a new approach to computer art
applications. Rather than operate in the traditional style of
pre-programmed rule-following systems, neural networks
have the power to learn to produce specific types of outputs
from specific inputs, based on examples they are taught.
Thus, instead of having to specify how to create a certain
artwork, the artist can instead teach a network examples of
the desired output, and have the network generate new
instances in that style. Several applications have been found
in Music area, ranging from psychological models of human
pitch, chord, and melody perception, to networks for
algorithmic
composition
and
performance
control.
Generally speaking, the applications here (and in other
fields) can be divided into two classes: “input” and
“output”. The input side includes networks for recognition
and understanding of a provided stimulus, for instance
speech recognition, or modeling how humans listen to and
process a melody. Such applications are useful for
communication from human to machine, and for artistic
analysis, of a set of inputs. The output side includes the
production of novel works, applications such as music
composition or drawing generation. As signal processors,
networks should find wide application in image
enhancement, color adjusting or altering, edge and line
modification, texture processing, etc. all based on learned
mappings from input pictures to desired outputs. The area of
neural network handwriting recognition is also being widely
explored. A network could be trained to take an image of a
face as input, and produce as output an image of that face
now displaying any of several chosen emotions: smiling,
frowning, staring, tongue stuck out, etc. Sequential
networks could be used to produce the step-by-step
movements of objects following some trajectory in space.
Networks can also find interesting use in real-world kinetic
applications, for controlling the motion of robots and
vehicles from single arms to self-driving automobiles. Art
forms including kinetic sculpture, machine dance,
automated music conducting, etc. are fertile areas for neural
network applications.
