Merged summary
TL;DR - A beginner-friendly explainer uses middle-school mathematics to show how neural networks learn, why nonlinear activation functions are essential, and how feed-forward networks process information inside Transformers.
- Training adjusts model parameters to minimize prediction error while aiming to generalize beyond memorized examples.
- Without nonlinear activations, stacked linear layers collapse into a single linear transformation and cannot model problems such as XOR.
- ReLU introduces nonlinear “bends,” enabling multilayer networks to approximate complex functions and learn hierarchical representations.
- In Transformers, attention gathers contextual information, while the feed-forward network nonlinearly transforms that information for each token.
