What is Backpropagation

Beginner
Backpropagation is the algorithm used to train neural networks by calculating how much each weight contributed to the final error and adjusting the weights to reduce that error.
Real-world example When a neural network mislabels a cat photo as a dog, backpropagation adjusts the internal weights so the next prediction is more likely to be correct.

How does Backpropagation work

Beginner
It works by first making a prediction, measuring the error, and then sending that error backward through the network layer by layer to update each weight using gradient descent.

What are common mistakes to avoid with Backpropagation

Intermediate
A common mistake with Backpropagation is applying it without fully understanding the underlying data or problem, which often leads to weak or misleading results. Skipping proper testing before relying on it in a real project is another frequent error.
