Decoupled Spatiotemporal Forecasting from Extreme Sparse Observations via Quantized Latent Space

AAAI 2026technical

Predicting spatiotemporal fields governed by partial differential equations (PDEs) from sparse sensor data is a critical and long-standing challenge in science and engineering. Recent deep learning approaches, particularly neural operators, have shown considerable promise in solving PDEs. However, t

MDCS-MoAME: Multi-directional Composite Scanning with Mixture of Attention and Mamba Experts for Cancer Survival Prediction

CVPR 2026

Multi-modal learning approaches that integrate pathological images with genomic profiles have significantly enhanced the accuracy of survival prediction tasks. However, previous methods often struggle to effectively process long-range gigapixel whole slide images (WSIs) and sparse genomic profiles d

PathwayLLM: Explainable Clinical Trajectory Modeling with Structured Pathways for Sepsis Prediction

ICML 2026poster

Patient-level sepsis prediction in the ICU requires models that track how a patient’s condition evolves over time and integrate heterogeneous structured evidence from electronic health records. We present PathwayLLM, a trajectory-based framework that grounds prediction on temporal signals together w…

LOHA: Direct Graph Spectral Contrastive Learning Between Low-Pass and High-Pass Views

AAAI 2025technical

Spectral Graph Neural Networks effectively handle graphs with different homophily levels, with low-pass filter mining feature smoothness and high-pass filter capturing differences. When these distinct filters could naturally form two opposite views for self-supervised learning, the commonalities bet…

RETAIN: Reliable Topology Augmentation for both Heterophilic and Homophilic Graphs

ICASSP 2025accepted

Current graph topology augmentation methods are mostly static and heavily rely on the assumption of homophily, where connected nodes are presumed to share the same labels by default. Due to the complexity of real-world graphs, the underlying assumption is often disrupted, thus performance declines,…
