Compositional Attribute Imbalance in Vision Datasets

AAAI 2026technical

Visual attribute imbalance is a common yet underexplored issue in image classification, significantly impacting model performance and generalization. In this work, we first define the first-level and second-level attributes of images and then introduce a CLIP-based framework to construct a visual at

Multimodal Meta-Verifier with Explicit Structured Recalibration

ICML 2026poster

Visual outcomes are increasingly central to multimodal large language models, making reliable and fine-grained verification essential for scaling generalist foundation models. In this work, we investigate ***multimodal meta-verification***, which leverages verifier-generated rationales rather than d…

Revisiting Point Cloud Shape Classification with a Simple and Effective Baseline

ICML 2021spotlight

Processing point cloud data is an important component of many real-world systems. As such, a wide variety of point-based approaches have been proposed, reporting steady benchmark improvements over time. We study the key ingredients of this progress and uncover two critical results. First, we find th…
