Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the biological analogue?Modeled after biological neural networks comprising interconnected neurons and synapses
2. What is the computational function?Mathematical models used to approximate nonlinear functions for AI problems
3. How do neural networks learn?They learn by changing the strength of their links, a process called backpropagation. The network adjusts its weights using an algorithm called gradient descent to reduce mistakes.
4. Why are neural networks useful?They help doctors spot diseases in pictures, translate languages, recognize faces, and even detect fraud. These tools make many jobs easier and safer.

Synaptic Plasticity: The ability of synapses to strengthen or weaken over time, crucial for learning in biological brains.
Backpropagation: An algorithm used to train artificial neural networks by calculating and propagating error gradients.
Deep Learning: A subset of machine learning that uses neural networks with multiple layers (deep architectures) to learn complex patterns.
