Eguard: Defending LLM Embeddings Against Inversion Attacks via Text Mutual Information Optimization

AAAI 2026technical

While text embeddings enable efficient semantic processing in LLMs, they remain vulnerable to inversion attacks that reconstruct sensitive original text. However, current defense methods typically treat text embeddings from the feature level independently, ignoring the exploitation of the mutual rel

NeuroDALEC: A Differentiable and Interpretable Mass-Conserving Framework for Terrestrial Ecosystem Carbon Cycle Dynamics

IJCAI 2026

Accurate simulation of terrestrial ecological carbon cycles is crucial for global climate change and ecosystem management. Process-based carbon models have high interpretability, but suffer from insufficient accuracy and slow computation due to fixed parameters. In contrast, deep-learning carbon mod

RipAlert: A Future-Frame-Aware Framework for Rip Current Forecasting and Early Alerting

AAAI 2026technical

Rip currents cause over 100 drowning deaths and more than 30,000 rescues annually in the United States, posing a severe threat to beach safety worldwide. However, most existing detection methods are reactive, identifying rip currents only after they form, leaving limited time for intervention. We pr

A Personalized Comfort Space With Variable Shape Based on Environmental Information for Robot Navigation in Homes

RA-L 2025

When a robot navigates in home environments, its trajectories need not only to avoid collisions but also to meet the psychological comfort of family members. We propose a personalized comfort space with variable shape based on environmental information to enhance the comfort perception of different

MCloudNet: An Ultra-Short-Term Photovoltaic Power Forecasting Framework With Multi-Layer Cloud Coverage

IJCAI 2025

Over 4.15 million low-income households across nearly 60,000 villages in China benefit from photovoltaic (PV) poverty alleviation power stations. However, weak infrastructure and limited capabilities make these systems vulnerable to fluctuations. One of the United Nations' Sustainable Development Go

Retinal Vessel Segmentation via a Semantics and Multi-Scale Aggregation Network

ICASSP 2020accepted

Precise segmentation of retinal vessels is crucial for a computer-aided diagnosis system of retinal fundus images. However, this task remains challenging due to large variations in scales and poor segmentation of capillary vessels. In this paper, we propose a semantics and multi-scale aggregation ne…
