MergOPT: A Merge-Aware Optimizer for Robust Model Merging

ICLR 2026poster

Model merging aims to integrate multiple independently fine-tuned expert models into a single model while preserving the knowledge of all experts. However, existing approaches mainly address parameter conflicts at the merging stage and overlook the role of the fine-tuning process, which often leads…

Merge to Remember: Sharpness-Aware Isotropic Merging for Continual Learning

ICML 2026poster

Continual learning with large pre-trained models offers significant potential for cross-task knowledge accumulation, but faces critical challenges such as catastrophic forgetting and parameter interference, especially when historical data is unavailable. Existing approaches typically rely on sequent…

FCConDubber: Fine And Coarse Grained Prosody Alignment For Expressive Video Dubbing via Contrastive Audio-Motion Pretraining

ICASSP 2025accepted

Automatic Video Dubbing (AVD) aims to synthesize speech that matches a character’s speaking style and emotion in silent video clips. However, existing approaches rely on attention mechanisms to learn cross-modal prosodic alignment implicitly, making it challenging to capture subtle prosodic variatio…

DCTTS: Discrete Diffusion Model with Contrastive Learning for Text-to-Speech Generation

ICASSP 2024accepted

In the Text-to-speech(TTS) task, the latent diffusion model has excellent fidelity and generalization, but its expensive resource consumption and slow inference speed have always been a challenging. To address this issue, this paper proposes the Discrete Diffusion Model with Contrastive Learning for…
