[21/08/2025] $\bullet$ We are thrilled to announce that our paper, “EMO-RL: Emotion-Rule-Based Reinforcement Learning Enhanced Audio-Language Model for Generalized Speech Emotion Recognition”, has been accepted to EMNLP 2025! In this work, we tackle key challenges in speech emotion recognition (SER) faced by large audio-language models (LALMs), such as emotional ambiguity and limited reasoning in smaller model architectures. By integrating emotion-constrained group-relative policy optimization into pretrained LALMs, EMO-RL significantly enhances emotional reasoning and stability during training.

In this work, we introduce a novel ODE solver that dramatically accelerates diffusion-based TTS models while preserving audio quality.

[26/06/2025] $\bullet$ Our latest paper, “Federated Domain Generalization with Domain-Specific Soft Prompts Generation,” has been accepted for presentation at the prestigious International Conference on Computer Vision (ICCV 2025)! The work represents a return to core research in Federated Learning, now powerfully combined with the cutting-edge field of Large Model Prompt Engineering. We introduce a novel framework that generates domain-specific soft prompts within the federated setting, significantly enhancing model generalization capabilities across unseen domains while preserving data privacy.

This achievement coincides with International Children’s Day, a fitting occasion to celebrate the milestone in our research journey. As a core cryptographic study, our work investigates privacy-preserving mechanisms for federated learning, underscoring the indispensable role of security theory in building trustworthy distributed systems. Through years of exploring federated learning’s challenges, we have affirmed that robust cryptographic frameworks are essential for securing data integrity and protecting user privacy in real-world applications.

[16/05/2025] $\bullet$ We are thrilled to announce that all three of our submissions to ACL 2025—two Main Conference papers and one Findings paper—have been accepted! (Main) Hierarchical-Task-Aware Multi-modal Mixture of Incremental LoRA Experts for Embodied Continual Learning. To unlock lifelong self-evolution in embodied AI, we propose a novel methodology integrating Mixture-of-Experts (MoE) with continual learning. Our hierarchical framework enables embodied agents to efficiently adapt to diverse scenarios while retaining prior knowledge, achieving state-of-the-art performance across multiple embodied tasks.(Findings)RATE-Nav: Region-Aware Termination Enhancement for Zero-shot Object Navigation with Vision-Language Models. Addressing the inefficiency of multimodal LLM-based navigation, RATE-Nav introduces a “marginal efficiency” paradigm for zero-shot object navigation. By dynamically predicting task termination based on region-aware visual-language reasoning, our method significantly reduces redundant exploration steps, outperforming existing approaches by a wide margin. (Main) MoQAE: Mixed-Precision Quantization for Long-Context LLM Inference via Mixture of Quantization-Aware Experts. Building on our DATE 2025 Best Paper-winning CockTail framework, MoQAE tackles the KV Cache bottleneck in long-context LLMs. We propose a novel MoE-inspired quantization strategy that allocates mixed-precision experts based on attention pattern criticality, achieving superior accuracy-efficiency trade-offs than prior arts.
