Episode 20 — Apply gradients and derivatives where they matter in model training
This episode explains gradients and derivatives as the engine behind many training processes, helping you answer DY0-001 questions that ask why optimization behaves the way it does. You’ll learn how a loss function measures error, how the gradient points toward the direction of steepest increase, and why training typically moves in the opposite direction to reduce loss. We’ll connect this to gradient descent, learning rate choices, and convergence behaviors, including what it looks like when the learning rate is too high, too low, or unstable due to noisy gradients. You’ll also see why scaling features and choosing appropriate activation functions can influence gradient flow, which becomes important when troubleshooting training that stalls or explodes. Best practices will include separating training and validation loss interpretation, using regularization to control complexity, and recognizing when the issue is not the optimizer but the data pipeline, labels, or leakage.
