Distribution-Based Feature Attribution for Explaining the Predictions of Any Classifier

AAAI 2026technical

The proliferation of complex, black-box AI models has intensified the need for techniques that can explain their decisions. Feature attribution methods have become a popular solution for providing post-hoc explanations, yet the field has historically lacked a formal problem definition. This paper ad

Expo-GS: Exposure-Aware Signed Distance Function in Gaussian Splatting for High Dynamic Range

ICML 2026poster

High dynamic range novel view synthesis (HDR-NVS) remains challenged by geometric artifacts and radiometric distortions under multi-exposure conditions, primarily due to existing methods ignoring exposure and over-relying on color cues. Inspired by the integrated processing of color and structure of…

Gauge Flow Matching: Efficient Constrained Generative Modeling over General Convex Set and Beyond

ICLR 2026poster

Generative models, particularly diffusion and flow-matching approaches, have achieved remarkable success across diverse domains, including image synthesis and robotic planning. However, a fundamental challenge persists: ensuring generated samples strictly satisfy problem-specific constraints — a cru…

Omni-MMSI: Toward Identity-attributed Social Interaction Understanding

CVPR 2026

We introduce Omni-MMSI, a new task that requires comprehensive social interaction understanding from raw audio, vision, and speech input. The task involves perceiving identity-attributed social cues (e.g., who is speaking what) and reasoning about the social interaction (e.g., whom the speaker refer

MEFLUT: Unsupervised 1D Lookup Tables for Multi-exposure Image Fusion

ICCV 2023poster

In this paper, we introduce a new approach for high-quality multi-exposure image fusion (MEF). We show that the fusion weights of an exposure can be encoded into a 1D lookup table (LUT), which takes pixel intensity value as input and produces fusion weight as output. We learn one 1D LUT for each exp…

Real3D-AD: A Dataset of Point Cloud Anomaly Detection

NeurIPS 2023poster

High-precision point cloud anomaly detection is the gold standard for identifying the defects of advancing machining and precision manufacturing. Despite some methodological advances in this area, the scarcity of datasets and the lack of a systematic benchmark hinder its development. We introduce Re…
