langchain_community.document_transformers.embeddings_redundant_filter.EmbeddingsClusteringFilter¶

class langchain_community.document_transformers.embeddings_redundant_filter.EmbeddingsClusteringFilter[source]¶

Bases: BaseDocumentTransformer, BaseModel

Perform K-means clustering on document vectors. Returns an arbitrary number of documents closest to center.

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

param embeddings: Embeddings [Required]¶

Embeddings to use for embedding document contents.

param num_closest: int = 1¶

The number of closest vectors to return for each cluster center.

param num_clusters: int = 5¶

Number of clusters. Groups of documents with similar meaning.

param random_state: int = 42¶

Controls the random number generator used to initialize the cluster centroids. If you set the random_state parameter to None, the KMeans algorithm will use a random number generator that is seeded with the current time. This means that the results of the KMeans algorithm will be different each time you run it.

param remove_duplicates: bool = False¶

By default duplicated results are skipped and replaced by the next closest vector in the cluster. If remove_duplicates is true no replacement will be done: This could dramatically reduce results when there is a lot of overlap between clusters.

param sorted: bool = False¶

By default results are re-ordered “grouping” them by cluster, if sorted is true result will be ordered by the original position from the retriever

async atransform_documents(documents: Sequence[Document], **kwargs: Any) Sequence[Document]¶

Asynchronously transform a list of documents.

Parameters
  • documents (Sequence[Document]) – A sequence of Documents to be transformed.

  • kwargs (Any) –

Returns

A list of transformed Documents.

Return type

Sequence[Document]

classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) Model¶

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

Parameters
  • _fields_set (Optional[SetStr]) –

  • values (Any) –

Return type

Model

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) Model¶

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters
  • include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model

  • exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include

  • update (Optional[DictStrAny]) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

  • deep (bool) – set to True to make a deep copy of the model

  • self (Model) –

Returns

new model instance

Return type

Model

dict(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) DictStrAny¶

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters
  • include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) –

  • exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) –

  • by_alias (bool) –
