fit_transform_documents(self, vector_fields: List[str], documents: List[Dict], alias: str, exclude_original_vectors: bool = True, dims: int = 3)#

This function takes a list of documents, a field name, and a dimensionality reduction algorithm, and returns a list of documents with a new field containing the dimensionality reduced vectors

  • vector_field (str) – The name of the field in the documents that contains the vectors to be reduced.

  • documents (List[Dict]) – The documents to transform.

  • alias (str) – The name of the new field that will be created in the documents.

  • exclude_original_vectors (bool, optional) – If True, the original vector field will be excluded from the returned documents.

  • dims (int, optional) – The number of dimensions to reduce the vectors to.

Return type

A list of documents with the original vector field and the new vector field.
