intermediateGeneralization: Measuring What a Model Actually Learned
Training error flatters every model. Learn how train, validation and test splits work, watch overfitting happen in computed numbers, and see how regularization, cross-validation and leak-proof pipelines give you a score you can trust on data the model has never seen.

intermediateTraining: Optimization and Regularization
Go from a raw neural network to one that actually generalizes. Covers loss functions (MSE, cross-entropy), gradient descent variants (SGD, momentum, Adam), learning-rate effects, overfitting vs underfitting, and the regularization toolkit (L2/dropout/early stopping/batch norm).
