For each pair of nodes connected by a link that indicates a similarity greater than a specified threshold, keeps only one of the two nodes and rewires the deleted node’s incoming and outgoing links to point to the “surviving” node.

duplicate_threshold
[number, null]
required

Similarity threshold for candidate nodes to be eliminated. Any node linked to another node with a weight (usually similarity) greater than this value will be eliminated. Default (null) corresponds to positive infinity (no de-duplication).
