Read In One Flow With Contextual Tooltips

Keep your momentum, learn as you go

Definitions appear exactly where you need them. Hover or click highlighted terms to reveal concise explanations without breaking your reading flow. This keeps complex topics coherent and reduces context switching.

  • Instant clarity on symbols and jargon
  • Stay immersed—no tab-hopping or glossary hunting
  • Perfect for layered topics like neural networks and transformers

Neural networks learn by composing linear transformations with non-linearactivation functionssuch as ReLU and sigmoid. During training,backpropagationcomputes gradients, and optimizers like stochasticgradient descentupdate the weights. Techniques likebatch normalizationanddropouthelp stabilize learning and reduce overfitting, while careful initialization mitigatesvanishing gradientsin very deep networks.
