Neural networks are everywhere today, powering everything from voice assistants to self-driving cars. But what exactly are they? Neural networks are a type of artificial intelligence modeled after the human brain. They consist of layers of interconnected nodes, or "neurons," that process data in complex ways. These networks learn from vast amounts of data, improving their performance over time. Imagine teaching a child to recognize animals by showing pictures; that's how neural networks learn. They can identify patterns, make predictions, and even create art. Curious about how these digital brains work? Here are 30 fascinating facts about neural networks that will blow your mind!
