What papers say

Verbatim critique sentences, each from a paper that cites B-LoRA as a baseline.

We attribute these issues to the inappropriate noise prediction loss used in existing LoRA-based methods~B-LoRA,ziplora, which fails to adequately focus on global and high-level features.
— ConsisLoRA: Enhancing Content and Style Consistency for LoRA-based Style Transfer
“However, such approaches, along with methods like B-LoRA, ComposLoRA, CMLoRA, remain heavily dependent on model-specific architectures rombach2022high,podell2023sdxl and domain constraints.”
— QR-LoRA: Efficient and Disentangled Fine-tuning via QR Decomposition for Customized Generation
“Despite these advancements, existing methods continue to face challenges, including insufficient control precision, loss of object style, and high training requirements.”
