Comparative Analysis of DeepAnT Online Hyperparameter Optimization and Adaptive OCSVM on the NAB Dataset

Abstract

Abstract: The demand for robust unsupervised anomaly detection in streaming data has grown significantly in the era of smart devices, where vast amounts of data are continuously collected from such devices. Leveraging this data through effective anomaly detection is essential and necessitates a system that can work in real-time. One of the most innovative solutions is the Online Evolving Spiking Neural Network (OeSNN). The OeSNN offers a robust framework for knowledge discovery in streaming data since it can evolve and adapt to new data patterns in real-time, thereby eliminating the need for retraining.

Research Question

In streaming anomaly detection scenarios, how does DeepAnT's online hyperparameter optimization for kernel ridge regression compare to adaptive models like OCSVM in terms of throughput and false positive rate when evaluated on the NAB (Numenta Anomaly Benchmark) dataset?

Verification Level

Descriptive public verification status only; aggregate claim counts are public, but individual claim records are not exposed here.

Truth-Engine Gate Verdict

This record has not completed Gate 2 of the verification pipeline (a type-checked Lean4 proof for mathematical claims, or a sealed-sandbox reproduction for empirical claims). It is a literature synthesis only. VERIFIED requires an attached reproducible artifact (Lean4 proof source, or repro script and results) before this status can be set; it is not derived from review score or claim count.

Quality Tier

Descriptive public triage only; this tier does not alter current publication or DOI behavior.

Quality Dimensions

Automated triage signals derived from public fields; not human peer review or independent validation.

Correction Record

Public corrections are additive records. Current status does not claim the synthesis is error-free.
