A Wearable Centaur Robot with Wheel-Legged Transformation for Enhanced Load-Carrying Assistance

IROS 2025

The execution of long-distance load-carrying tasks across multiple terrains remains a frequent requirement. These tasks often involve heavy loads, resulting in fatigue, decreased efficiency, and potential safety risks. To address this issue, this paper proposes a wearable centaur robot with wheel-le

Neural Parameter Search for Slimmer Fine-Tuned Models and Better Transfer

ACL 2025long

Foundation models and their checkpoints have significantly advanced deep learning, boosting performance across various applications. However, fine-tuned models often struggle outside their specific domains and exhibit considerable redundancy. Recent studies suggest that combining a pruned fine-tuned…

To See a World in a Spark of Neuron: Disentangling Multi-Task Interference for Training-Free Model Merging

EMNLP 2025

Fine-tuning pre-trained models on targeted datasets enhances task-specific performance but often comes at the expense of generalization. Model merging techniques, which integrate multiple fine-tuned models into a single multi-task model through task arithmetic, offer a promising solution. However, t

Parameter Competition Balancing for Model Merging

NeurIPS 2024poster

While fine-tuning pretrained models has become common practice, these models often underperform outside their specific domains. Recently developed model merging techniques enable the direct integration of multiple models, each fine-tuned for distinct tasks, into a single model. This strategy promote…
