You use them every day. Here's how they actually work.
It takes something in and gives you something useful back.
Layers of neurons wired together — same idea as your brain.
Data enters on the left. Each layer picks up on different patterns. By the time it reaches the output, the network has its answer.
Neurons connected by synapses. Learns from experience.
Digital neurons connected by weights. Learns from data.
It starts wrong. Then it keeps practicing until it's not.
Takes a shot at the answer
Was it right or wrong?
Changes connections to do better
Thousands of times until it nails it
Every round, it gets a little better.
This is called training. More examples = better results.
Every time you unlock your phone, a neural network does all of the above.
Camera scans you
Runs your face through layers of pattern matching
Match? Unlock. No match? Stay locked.
Input, layers, output, trained from data — all happening in under a second.
Take something in. Run it through layers. Give an answer. Learn from mistakes. Get better.
That's a neural network.
