Conversation
Adds a zero-centered reparameterization option to RMSNorm and LayerNormConfig that reparameterizes the scale as (1 + weight) with weight initialized to zero, instead of the standard initialization to one. This allows a more natural weight decay behavior on the scale parameter, since it will decay towards zero (no scaling).
