How do neural networks learn and make decisions?<end_of_turn>
<start_of_turn>model
Neural networks, inspired by the human brain, are a type of artificial intelligence (AI) that learn by processing information through interconnected layers of "neurons". Each neuron receives inputs, performs calculations, and outputs a signal to the next layer. This intricate web of connections allows the network to gradually learn patterns and relationships within the data it's trained on.

Imagine showing a network thousands of pictures of cats and dogs. Each neuron in the first layer might detect simple features like edges or textures. As information flows through subsequent layers, the network learns to combine these features and recognize complex patterns like ears, whiskers, or fur textures. Eventually, the network can differentiate cats from dogs with impressive accuracy.

The learning process involves adjusting the "weights" on the connections between neurons. Think of weights as tiny dials that control the strength of the signal. Through training algorithms, the network adjusts these weights based on how well it performs on its tasks. If it misclassifies a picture, the weights are adjusted to encourage the network to learn from its mistakes.

The key takeaway is that neural networks don't explicitly "understand" or "reason" about the data, but they learn to recognize patterns and make predictions based on the intricate relationships they discover within the information. It's a fascinating blend of math, statistics, and computational power that allows these systems to perform increasingly complex tasks.<end_of_turn><eos>
