Span Pooler

The eds.span_pooler component is a trainable span embedding component. It generates span embeddings from a word embedding component and a span getter. It can be used to train a span classifier, as in eds.span_classifier.

Parameters

PARAMETER	DESCRIPTION
`nlp`	The pipeline object
`name`	Name of the component
`embedding`	The word embedding component TYPE: `WordEmbeddingComponent`
`pooling_mode`	How word embeddings are aggregated into a single embedding per span. DEFAULT: `mean`
`hidden_size`	The size of the hidden layer. If None, no projection is done and the output of the span pooler is used directly. TYPE: `Optional[int]` DEFAULT: `None`
