AD-GBC: Anisotropic Granular-Ball Skip-Connection Refiner for UNet-Based Medical Image Segmentation

CVPR 2026

Prototype or region-attention modules have recently improved medical image segmentation but still suffer from two fundamental limitations: 1) they represent each semantic concept as a point or isotropic region, failing to capture the inherently anisotropic geometry of real feature distributions; and

Hierarchical Schedule Optimization for Fast and Robust Diffusion Model Sampling

AAAI 2026technical

Diffusion probabilistic models have set a new standard for generative fidelity but are hindered by a slow iterative sampling process. A powerful training-free strategy to accelerate this process is Schedule Optimization, which aims to find an optimal distribution of timesteps for a fixed and small N

SIM-MSTNET: SIM2REAL BASED MULTI-TASK SPATIOTEMPORAL NETWORK TRAFFIC FORECASTING

ICASSP 2026oral

Network traffic forecasting plays a crucial role in intelligent network operations, but existing techniques often perform poorly when faced with limited data. Additionally, multi-task learning methods struggle with task imbalance and negative transfer, especially when modeling various service types.…

Learning Optimal K-Space Acquisition and Reconstruction Using Physics-Informed Neural Networks

CVPR 2022poster

The inherent slow imaging speed of Magnetic Resonance Image (MRI) has spurred the development of various acceleration methods, typically through heuristically undersampling of the associated measurement domain known as k-space. Recently, deep neural networks have been applied to reconstruct undersam…
