transformer_lens.components.unembed

Hooked Transformer Unembed Component.

This module contains all the component Unembed.

class transformer_lens.components.unembed.Unembed(cfg: Union[Dict, HookedTransformerConfig])

Bases: Module

forward(residual: Float[Tensor, 'batch pos d_model']) → Float[Tensor, 'batch pos d_vocab_out']

Defines the computation performed at every call.

Should be overridden by all subclasses.

Note

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
