Overview
Artificial Neural Networks are computing systems inspired by the biological brain. They process information through interconnected processing units called neurons, and they are used for tasks such as pattern recognition, classification, and regression. The first artificial neural network was the Per
Key Concepts
An ANN is a computing system
An ANN is a computing system inspired by the biological brain. It works through interconnected neurons and learns from data by adjusting weights.
Perceptron was the first artificial neural
Perceptron was the first artificial neural network, invented in 1958 by Frank Rosenblatt. It was intended to model how the human brain processes visua
A neuron has four parts
A neuron has four parts: dendrites, soma, axon, and synapses. Dendrites receive information, soma processes it, axon sends it onward, and synapses con
The input layer receives raw data
The input layer receives raw data with no processing. It corresponds to dendrites in a neuron.
Hidden layers perform feature extraction
Hidden layers perform feature extraction and complex computation. They process the information received from previous layers and help the network lear
