class SentenceEmbeddings extends AnnotatorModel[SentenceEmbeddings] with HasSimpleAnnotate[SentenceEmbeddings] with HasEmbeddingsProperties with HasStorageRef

This annotator converts the results from WordEmbeddings, BertEmbeddings, or ElmoEmbeddings into sentence or document embeddings by either summing up or averaging all the word embeddings in a sentence or a document (depending on the inputCols).

See https://github.com/JohnSnowLabs/spark-nlp/blob/master/src/test/scala/com/johnsnowlabs/nlp/embeddings/SentenceEmbeddingsTestSpec.scala for further reference on how to use this API.
