1980s: The Emergence of “Neural Networks” and Their Importance in Pattern Recognition:

In the 1980s, an interest in neural networks was inspired by the biological neural networks of the human brain. Neural networks are interconnected layers of nodes, or "neurons," that process information in a manner not unlike human cognition. This architectural design enables neural networks to learn complex patterns and relationships from data, making them particularly well-suited for tasks like pattern recognition and classification.

How Artificial Neural Networks(ANN) Work

ANNs learn through a process called training. During training, the network is presented with a set of labeled data examples. The network processes the input data, generates an output, and compares it to the correct label. The error is the difference between the predicted output and the actual label.

The network then uses an algorithm to adjust the weights of the connections between the nodes. This process of adjusting weights is called backpropagation. By iteratively feeding the network data and adjusting the weights, the network gradually learns to map the input data to the desired output.

In the example below, the inputs are “The Car Is” and based on the weights of the connections between the nodes, the given output is “Red”.
