BasicTextFieldEmbedder

@TextFieldEmbedder.register("basic")
class BasicTextFieldEmbedder(TextFieldEmbedder):
 | def __init__(self, token_embedders: Dict[str, TokenEmbedder]) -> None

This is a TextFieldEmbedder that wraps a collection of TokenEmbedder objects. Each TokenEmbedder embeds or encodes the representation output from one allennlp.data.TokenIndexer. As the data produced by a allennlp.data.fields.TextField is a dictionary mapping names to these representations, we take TokenEmbedders with corresponding names. Each TokenEmbedders embeds its input, and the result is concatenated in an arbitrary (but consistent) order.

Registered as a TextFieldEmbedder with name "basic", which is also the default.

Parameters

• token_embedders : Dict[str, TokenEmbedder]
  A dictionary mapping token embedder names to implementations. These names should match the corresponding indexer used to generate the tensor passed to the TokenEmbedder.
