Sketch Models¶

Public objects from aberrant.model.sketch:

• MStream
• StreamingLODA
• StreamingRSHash

StreamingLODA is a bounded-memory random-projection histogram detector.

MStream is a bounded-memory streaming detector based on fixed-size sketches.

StreamingRSHash is a bounded-memory randomized subspace hashing detector.

LODA and RSHash remain compatibility aliases for these bounded streaming adaptations; they do not imply paper-procedure or score parity.

Notes: - Supports optional explicit timestamp handling via time_key. - Returns continuous non-negative anomaly scores.
