Neural networks consist of interconnected nodes called artificial neurons or units, which are organized in layers. Each neuron takes in inputs, processes them, and produces an output, which becomes the input for the next layer of neurons. This process continues until the network produces the final desired output. The connections between the neurons have associated weights, which determine the strength and significance of the inputs. Through a training process, these weights are adjusted to optimize the network’s performance.

Neurons in the human brain work similarly to artificial neurons. Information flows through the brain’s neural network in the form of electrical impulses. When a neuron receives an input, it evaluates the inputs collectively and decides whether to pass the signal to the next neuron. This decision-making is influenced by the strength and type of connections between the neurons. Both neural networks and the brain exhibit the ability to adapt and learn from experience, which is crucial for tasks such as recognition, prediction, and decision-making.
