A Bayesian Approach to Quantify the Uncertainty of Human Ratings in a Single-Instance Multimodal Framework

ICML 2026poster

Human ratings are central to learning and inference across several application domains, but they are also subject to inter-rater biases and judgment errors. Quantifying the uncertainty of these human ratings would require repeated measurements, which are expensive and rarely available at scale. We p…

Refine-IQA: Multi-Stage Reinforcement Finetuning for Perceptual Image Quality Assessment

AAAI 2026technical

Reinforcement fine-tuning (RFT) is a proliferating paradigm for LMM training. Analogous to high-level reasoning tasks, RFT is similarly applicable to low-level vision domains, including image quality assessment (IQA). Existing RFT-based IQA methods typically use rule-based output rewards to verify

VITAL: Vision-Encoder-centered Pre-training for LMMs in Visual Quality Assessment

CVPR 2026

Developing a robust visual quality assessment (VQualA) large multi-modal model (LMM) requires achieving versatility, powerfulness, and transferability. However, existing VQualA LMMs typically focus on a single task and rely on full-parameter fine-tuning, which makes them prone to overfitting on spec

Filtration-Enhanced Graph Transformation

IJCAI 2022poster

Graph kernels and graph neural networks (GNNs) are widely used for the classification of graph data. However, many existing graph kernels and GNNs have limited expressive power, because they cannot distinguish graphs if the classic 1-dimensional Weisfeiler-Leman (1-WL) algorithm does not distinguish…
