CAUSAL-SAM-LLM: LARGE LANGUAGE MODELS AS CAUSAL REASONERS FOR ROBUST MEDICAL SEGMENTATION

ICASSP 2026oral

The clinical utility of deep learning models for medical image segmentation is severely constrained by their inability to generalize to unseen domains. This failure is often rooted in the models learning spurious correlations between anatomical content and domain-specific imaging styles. To overcome…

WAVELET-AWARE ANOMALY DETECTION IN MULTI-CHANNEL USER LOGS VIA DEVIATION MODULATION AND RESOLUTION-ADAPTIVE ATTENTION

ICASSP 2026poster

Insider threat detection is a key challenge in enterprise security, relying on user activity logs that capture rich and complex behavioral patterns. These logs are often multi-channel, non-stationary, and anomalies are rare, making anomaly detection challenging. To address these issues, we propose a…

The Panaceas for Improving Low-Rank Decomposition in Communication-Efficient Federated Learning

ICML 2025poster

To improve the training efficiency of federated learning (FL), previous research has employed low-rank decomposition techniques to reduce communication overhead. In this paper, we seek to enhance the performance of these low-rank decomposition methods. Specifically, we focus on three key issues rel…

FedBAT: Communication-Efficient Federated Learning via Learnable Binarization

ICML 2024poster

Federated learning is a promising distributed machine learning paradigm that can effectively exploit large-scale data without exposing users' privacy. However, it may incur significant communication overhead, thereby potentially impairing the training efficiency. To address this challenge, numerous…
