PILO: Principal Component-based Implicit Regularization with Low-rank Optimization for Robust Transfer Learning

IJCAI 2026

Adapting large, adversarially pre-trained models to specialized domains via transfer learning is a promising path toward building secure AI systems. However, a critical challenge arises when fine-tuning on limited downstream data: models often suffer from catastrophic forgetting of robustness, where

SFedHIFI: Fire Rate-Based Heterogeneous Information Fusion for Spiking Federated Learning

AAAI 2026technical

Spiking Federated Learning (SFL) has been widely studied with the energy efficiency of Spiking Neural Networks (SNNs). However, existing SFL methods require model homogeneity and assume all clients have sufficient computational resources, resulting in the exclusion of some resource-constrained clien

Sparsely Timing the Change: A Spiking Temporal Framework for Remote Sensing Interpretation

CVPR 2026

The temporal evolution patterns of surface spatial structures constitute a central concern within the field of intelligent remote sensing interpretation.However, constrained by the availability of only two temporal phases, modeling sparse spatio-temporal change processes to effectively interpret sur

Flexible Sharpness-Aware Personalized Federated Learning

AAAI 2025technical

Personalized federated learning (PFL) is a new paradigm to address the statistical heterogeneity problem in federated learning. Most existing PFL methods focus on leveraging global and local information such as model interpolation or parameter decoupling. However, these methods often overlook the ge…
