ConDSeg: A General Medical Image Segmentation Framework via Contrast-Driven Feature Enhancement

AAAI 2025technical

Medical image segmentation plays an important role in clinical decision making, treatment planning, and disease tracking. However, it still faces two major challenges. On the one hand, there is often a "soft boundary" between foreground and background in medical images, with poor illumination and lo…

Robust Spoof Speech Detection Based on Multi-Scale Feature Aggregation and Dynamic Convolution

ICASSP 2024accepted

Spoof speech detection (SSD) can help to protect an automatic speaker recognition system against malicious attacks. However, there exists a great diversity in the spoof utterances generated by different text-to-speech and voice conversion algorithms, resulting in a poor generality of an SSD system t…

Evaluating Emergent Coordination in Multi-Agent Task Allocation Through Causal Inference and Sub-Team Identification

RA-L 2023

Coordination in multi-agent systems is a vital component in teaming effectiveness. In dynamically changing situations, agent decisions depict emergent coordination strategies from following pre-defined rules to exploiting incentive-driven policies. While multi-agent reinforcement learning shapes tea

Task Allocation with Load Management in Multi-Agent Teams

ICRA 2022poster

In operations of multi-agent teams ranging from homogeneous robot swarms to heterogeneous human-autonomy teams, unexpected events might occur. While efficiency of operation for multi-agent task allocation problems is the primary objective, it is essential that the decision-making framework is intell…

Impact of Heterogeneity and Risk Aversion on Task Allocation in Multi-Agent Teams

RA-L 2021

Cooperative multi-agent decision-making is a ubiquitous problem with many real-world applications. In many practical applications, it is desirable to design a multi-agent team with a heterogeneous composition where the agents can have different capabilities and levels of risk tolerance to address di
