What is Gradient Descent
Beginner
Gradient descent is the optimization algorithm used to train neural networks by gradually adjusting weights in the direction that reduces the loss function.
Real-world example
Gradient descent slowly nudges a model's weights closer to the values that produce the most accurate predictions over many training steps.

How does Gradient Descent work
Beginner
It calculates the slope, or gradient, of the loss function with respect to each weight, then updates the weights slightly in the opposite direction of that slope to reduce error.

What are common mistakes to avoid with Gradient Descent
Intermediate
A common mistake with Gradient Descent 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.
