Introduction To Neural Networks Part I Neural Networks A small intro Introduction ToNeural Networks Development of Neural Networks date back to the early 1940s. It experienced an upsurge in popularity in the late 1980s. This was a result of the discovery of new techniques and developments and general advances in computer hardware technology. Some NNs are models of biological neural

Comparison between biological neuron and artificial neuron Basic models of ANN Different types of connections of NN, Learning and activation function Basic fundamental neuron model-McCulloch-Pitts neuron and Hebb network

Artificial Neural Networks A neural network is a massively parallel, distributed processor made up of simple processing units artificial neurons. It resembles the brain in two respects

A perceptron network can solve XOR but we cannot train an entire network Threshold Functions The perceptron provides a binary output based on whether the function computed x1w1x2w2 gt t or ltt such a function is known as a linear threshold or a bipolar linear threshold When we connect multiple neurons together to form a perceptron

Multi-layer perceptrons To make nonlinear classifiers out of perceptrons, build a multi-layer neural network! This requires each perceptron to have a nonlinearity

Title Introduction to Neural Networks 1 Introduction to Neural Networks CS405 2 What are connectionist neural networks? Connectionism refers to a computer modeling approach to computation that is loosely based upon the architecture of the brain. Many different models, but all include Multiple, individual nodes or units that operate at the same time in parallel A network that connects the

Introduction What are Neural Networks? Neural networks are a new method of programming computers. They are exceptionally good at performing pattern recognition and other tasks that are very difficult to program using conventional techniques. Programs that employ neural nets are also capable of learning on their own and adapting to changing conditions.
