What is an Artificial Neural Network (ANN) / Neural Network?

Definition

An Artificial Neural Network (ANN) or Neural Network is a computing model inspired by the structure and functioning of the human brain, designed to simulate the interconnectivity of neurons. These networks make decisions by processing layers of input through nodes, or 'artificial neurons', each having assigned weights and thresholds. A node surpassing its threshold activates and transmits data to subsequent layers, mimicking neural pathways. ANNs are especially potent in tasks requiring pattern recognition, classification, or clustering, as they are capable of improving accuracy through iterative training with data, underpinning advancements in machine learning and AI.
