What is the fundamental concept behind neural networks?

The fundamental concept behind neural networks is to mimic the functioning of the human brain to solve complex problems. Neural networks are computational models inspired by the biological structure and functioning of the brain's interconnected neurons. At the core of neural networks is the concept of artificial neurons, also known as perceptrons. These artificial neurons receive input signals, process them through an activation function, and produce an output signal. The activation function determines the neuron's response based on the input it receives. Neural networks consist of multiple interconnected layers of artificial neurons. The input layer receives the initial input data, and subsequent hidden layers process and transform the information through wei....
