IFCLoRA: Topology-Aware Rank Allocation for Parameter-Efficient Fine-Tuning

Wei Zhang, Xinwu Liu, Y Cheng

Low-Rank Adaptation (LoRA) is a widely used approach to parameter-efficient fine-tuning (PEFT) of LLMs whose effectiveness depends on rank allocation. Existing adaptive LoRA methods derive ranks from local gradient, activation, or matrix statistics collected before or during fine-tuning; training-time variants add overhead, …

Research on 3D Virtual Scene Reconstruction and Application Based on Multi-source Data Fusion

Hao Tang, Yuhang Wang, Xinwu Liu, Ziyi Wang et autres

Abstract. As digital cities evolve, the demand for 3D reconstruction increases, but challenges in accuracy and completeness remain.This study proposes a 3D virtual scene reconstruction and application framework, which overcomes the limitations of single-source data by incorporating multi-source data, improving accuracy, completeness, …
