Is Task-Specific Training Necessary for Anomaly Detection?

Xingwu Zhang, Guanxuan Li, Paul Henderson +2

Current state-of-the-art multi-class unsupervised anomaly detection (MUAD) methods rely on training encoder--decoder models to reconstruct anomaly-free features. However, we argue…

Eliminating Hallucination in Diffusion-Augmented Interactive Text-to-Image Retrieval

Zhuocheng Zhang, Kangheng Liang, Guanxuan Li +3

Diffusion-Augmented Interactive Text-to-Image Retrieval (DAI-TIR) is a promising paradigm that improves retrieval performance by generating query images via diffusion models and us…

Masked Generative Policy for Robotic Control

Lipeng Zhuang, Shiyu Fan, Florent P. Audonnet +4

We present Masked Generative Policy (MGP), a novel framework for visuomotor imitation learning. We represent actions as discrete tokens, and train a conditional masked transformer…

3D-ADAM: A Dataset for 3D Anomaly Detection in Additive Manufacturing

Paul McHard, Florent P. Audonnet, Oliver Summerell +3

Surface defects are a primary source of yield loss in manufacturing, yet existing anomaly detection methods often fail in real-world deployment due to limited and unrepresentative…

Diffusion Augmented Retrieval: A Training-Free Approach to Interactive Text-to-Image Retrieval

Zijun Long, Kangheng Liang, Gerardo Aragon-Camarasa +2

Interactive Text-to-image retrieval (I-TIR) is an important enabler for a wide range of state-of-the-art services in domains such as e-commerce and education. However, current meth…
