Why the choices matter

Activation saturation

Sigmoid and tanh can compress large inputs into flat regions. Their tiny derivatives weaken gradients across many layers.

Initialization scale

Xavier, He, and LeCun methods match weight variance to network structure. Better scaling preserves signal strength during forward and backward passes.

Residual paths

Shortcut connections create shorter routes for information and gradients. They make very deep networks easier to optimize.

Recurrent memory

LSTM and GRU gates preserve useful state across longer sequences. Vanilla recurrent networks lose distant information more easily.
