Unverified50% confidenceFactExact time
LoRA freezes the base model weights and learns low-rank updates, but does not guarantee that all prior behaviors are preserved, requiring regression testing beyond the target task.

UnverifiedA frozen model refers to a model whose weight parameters all remain unchanged during the inference phase, with no fine-tuning, adapter training, or online learning performed.72% similarUnverified当前的LLM一旦完成训练其参数即被冻结，只能通过微调或RAG等外部机制来更新72% similarUnverifiedThe systematic process for debugging a non-converging model is to first verify on a very small data subset whether the model can overfit; if it cannot overfit even on small data, it indicates a bug in the model or training code.72% similarUnverifiedLoRA only needs to be overlaid on the base model during inference with a relatively limited increase in VRAM usage, which is one of the important technical prerequisites that allowed the character swap task to run on an 8 GB VRAM configuration.71% similarVerifiedLoRA是以参数高效微调（PEFT）为代表的主流微调方法，核心思想是在不改动原始模型权重的前提下向特定层注入低秩矩阵，只训练新增参数71% similar
