UnverifiedLoRA achieves parameter-efficient fine-tuning by superimposing low-rank decomposition matrices onto pre-trained model weights, delivering the highest consistency, but each new character requires dozens of reference images and hours of training, resulting in high engineering costs.76% similarVerifiedLoRA reduces fine-tuning costs by training only a small number of adapter layers (low-rank matrix bypass training).76% similarUnverifiedLoRA中A使用随机高斯初始化，B初始化为零，以确保训练开始时叠加量为零、不破坏原模型能力，推理时不引入额外延迟75% similar
