icat.anchors.TFIDFAnchor

class icat.anchors.TFIDFAnchor(container=None, *args, **kwargs)

Bases: SimilarityAnchorBase

A similarity anchor that uses cosine similarity between the TF-IDF vectors of the text data and the target texts.

Attributes

DESCRIPTION	Subclasses of Anchor can define this DESCRIPTION to show up in the UI explaining the given anchor type.
NAME	Subclasses of Anchor can define this NAME to show up in the UI as the default name for this anchor type.
anchor_name	Not to be confused with just name, which is the panel component id.
global_cache	An anchor list level cache, (dictionary of key-value pairs) any keys set here are accessible by all other anchors.
in_model	Whether to include this feature in the training process.
in_view	Whether to show this anchor in anchorviz.
name
param
reference_short	A shortform version of the texts, either the row IDs if available, or just the first few words
reference_texts	The target texts to calculate the similarity to.
text_col	The text column from the data to use when measuring similarity.
weight	Scalar multiple to apply to all output features, the user can change this to modify how much a particular feature influences the model.
cache	A dictionary of key-value pairs specific to this one anchor instance that gets saved when save() is called (by default).
