Making Parametric Anomaly Detection on Tabular Data Non-Parametric Again. (arXiv:2401.17052v1 [cs.LG])
cs.LG updates on arXiv.org arxiv.org
Deep learning for tabular data has garnered increasing attention in recent
years, yet employing deep models for structured data remains challenging. While
these models excel with unstructured data, their efficacy with structured data
has been limited. Recent research has introduced retrieval-augmented models to
address this gap, demonstrating promising results in supervised tasks such as
classification and regression. In this work, we investigate using
retrieval-augmented models for anomaly detection on tabular data. We propose a
reconstruction-based approach in which a transformer …
