Research Paper
Core Innovation
This paper introduces a novel dual-model ensemble using knowledge distillation to two heterogeneous student networks specialized for different anomaly types. It leverages a shared pre-trained encoder and a Noisy-OR objective to jointly learn and combine local and semantic anomaly scores. This approach outperforms prior single-model and specialist methods in both industrial and semantic anomaly detection across multiple datasets.

Research Paper Overview
Generalist Multi-Class Anomaly Detection via Distillation to Two Heterogeneous Student Networks
Summary
This paper proposes a dual-model ensemble approach using knowledge distillation for anomaly detection across industrial and semantic domains. It combines an Encoder-Decoder model for patch-level defect detection and an Encoder-Encoder model for semantic anomalies, both sharing a pre-trained DINOv2 encoder. The models are jointly trained with a Noisy-OR objective to produce a unified anomaly score. Evaluated on eight benchmarks, the method achieves state-of-the-art accuracy in both single-class and multi-class settings, demonstrating strong generalization across diverse anomaly detection tasks.
