ReTabAD: A Benchmark for Restoring Semantic Context in Tabular Anomaly Detection

ICLR 2026poster

In tabular anomaly detection (AD), textual semantics often carry critical signals, as the definition of an anomaly is closely tied to domain-specific context. However, existing benchmarks provide only raw data points without semantic context, overlooking rich textual metadata such as feature descrip…

Diffusion-based Semantic Outlier Generation via Nuisance Awareness for Out-of-Distribution Detection

AAAI 2025technical

Out-of-distribution (OOD) detection, determining whether a given sample is part of the in-distribution (ID) or not, has been newly explored by a generative model-based outlier synthesizing approach, especially with diffusion models. Nonetheless, existing diffusion models often produce outliers that…

ImagePiece: Content-aware Re-tokenization for Efficient Image Recognition

AAAI 2025technical

Vision Transformers (ViTs) have achieved remarkable success in various computer vision tasks. However, ViTs have a huge computational cost due to their inherent reliance on multi-head self-attention (MHSA), prompting efforts to accelerate ViTs for practical applications. To this end, recent works ai…

Representation Space Augmentation for Effective Self-Supervised Learning on Tabular Data

AAAI 2025technical

Tabular data, widely used across industries, remains underexplored in deep learning. Self-supervised learning (SSL) shows promise for pre-training deep neural networks (DNNs) on tabular data, but its potential is hindered by challenges in designing suitable augmentations. Unlike image and text data,…
