S2-Boost: Synergistic Semantic Boosting for Coarse-to-Fine Ensemble Learning

AAAI 2026technical

Neuroscientific evidence reveals that human visual recognition is not an instantaneous event but a hierarchical process, where the brain constructs a holistic perception by progressively integrating simple features like edges or texture into complex scenes. Ensemble learning successfully utilizes th

Towards Federated Clustering: A Client-wise Private Graph Aggregation Framework

AAAI 2026technical

Federated clustering addresses the critical challenge of extracting patterns from decentralized, unlabeled data. However, it is hampered by the flaw that current approaches are forced to accept a compromise between performance and privacy: transmitting embedding representations risks sensitive data

Language Pre-training Guided Masking Representation Learning for Time Series Classification

AAAI 2025technical

The representation learning of time series has a wide range of downstream tasks and applications in many practical scenarios. However, due to the complexity, spatiotemporality, and continuity of sequential stream data, compared with the representation learning of structural data such as images/video…

Self-Supervised Localized Topology Consistency for Noise-Robust Hyperspectral Image Classification

ICASSP 2025accepted

Label noise in hyperspectral image classification (HIC) can severely degrade model performance by leading to incorrect predictions and overfitting, especially as erroneous labels propagate and compound throughout the training process. To address this, we propose a robust learning framework called Se…

Perturbation Guiding Contrastive Representation Learning for Time Series Anomaly Detection

IJCAI 2024poster

Time series anomaly detection is a critical task with applications in various domains. Due to annotation challenges, self-supervised methods have become the mainstream approach for time series anomaly detection in recent years. However, current contrastive methods categorize data perturbations int…
