Overview
A neural network is a model inspired by the human brain and nervous system. It tries to simulate the way a brain processes, learns, and remembers information. Neural networks were first proposed in 1944 by Warren McCullough and Walter Pitts, and the first artificial neural network, called Perceptron
Key Concepts
A typical neuron has four parts
A typical neuron has four parts: dendrites, soma, axon, and synapses. Dendrites receive information, soma processes it, axon sends information out, an
A neural network is a series
A neural network is a series of algorithms loosely modelled after how neurons in the human brain behave. It learns from patterns in data and makes dec
The input layer is the first
The input layer is the first layer of a neural network. It acquires data and feeds it to the network. No processing occurs here. It corresponds to den
Hidden layers are the layers where
Hidden layers are the layers where all processing occurs. They are not visible to the user, and the number of hidden layers and nodes depends on the c
The output layer gives the final
The output layer gives the final output to the user. It does not process data and is meant for user-interface. It corresponds to the axon in a neuron.
Learning Objectives
