MixLoRA: Enhancing Large Language Models Fine-Tuning with LoRA based Mixture of Experts

1 code implementation22 Apr 2024 Dengchun Li, Yingzi Ma, Naizheng Wang, Zhiyuan Cheng, Lei Duan, Jie Zuo, Cal Yang, Mingjie Tang

Unlike other LoRA based MoE methods, MixLoRA enhances model performance by utilizing independently configurable attention-layer LoRA adapters, supporting the use of LoRA and its variants for the construction of experts, and applying auxiliary load balance loss to address the imbalance problem of the router.

Augmenting Ground-Level PM2.5 Prediction via Kriging-Based Pseudo-Label Generation

no code implementations16 Jan 2024 Lei Duan, Ziyang Jiang, David Carlson

We show that the proposed data augmentation strategy helps enhance the performance of the state-of-the-art convolutional neural network-random forest (CNN-RF) model by a reasonable amount, resulting in a noteworthy improvement in spatial correlation and a reduction in prediction error.

Probing the superconducting gap structure in the noncentrosymmetric topological superconductor ZrRuAs

no code implementations20 Jan 2021 Debarchan Das, D. T. Adroja, M. R. Lees, R. W. Taylor, Z. S. Bishnoi, V. K. Anand, A. Bhattacharyya, Z. Guguchia, C. Baines, H. Luetkens, G. B. G. Stenning, Lei Duan, Xiancheng Wang, Changqing Jin

The superconducting gap structure of a topological crystalline insulator (TCI) candidate ZrRuAs ($T^{\rm on}_{\rm c}$ = 7. 9(1) K) with a noncentrosymmetric crystal structure has been investigated using muon spin rotation/relaxation ($\mu$SR) measurements in transverse-field (TF) and zero-field (ZF) geometries.
