Graph Models

Public objects from aberrant.model.graph:

  • AnoEdgeL
  • ISCONNA
  • MIDAS
  • SignedGraphSketchDetector

AnoEdgeL maintains the local dense submatrices from the authors' higher-order count-min sketch implementation.

ISCONNA implements the authors' frequency, consecutive-width, and gap pattern scores.

MIDAS is a bounded-memory microcluster detector for dynamic edge streams.

SignedGraphSketchDetector is a bounded-memory structural detector using signed count sketches and online Euclidean centroids. StreamSpot remains a compatibility alias; the variant does not reproduce the original Hamming-sketch clustering workflow.

Notes: - Expects source and destination node identifiers per sample. - Supports optional explicit timestamp handling via time_key. - Returns continuous non-negative anomaly scores.
