Prefix Tuning 在prefix-tuning之前的工作主要是人工设计离散的template或者自动化搜索离散template,问题在于最终的性能对人工设计的template的特别敏感:加一个词或者少一个词,或者变动位置,都会造成很大的变化,所以这种离散化的token的搜索出来的结果可能并不是最优的。Prefix Tuning方法使用连续的virtual token embedding来...
Parameter-efficient tuning enables fine-tuning an LLM on a new task without retraining all its parameters, often counted in billions. Instead, a small subset of the model’s parameters or additional parameters are fine-tuned while the rest remain frozen. This “delta tuning” [1] approach can...

Parameter-Efficient Finetuning Prompt Tuning And Prefix Tuning Adapters Extending Prefix Tuning and Adapters: LLaMA-Adapter Conclusion Finetuning Large Language Models Since GPT-2 (Radford et al.) and GPT-3 (Brown et al.), we have seen that generative large language models (LLMs) pretrained on...

In this work, we focus on Parameter-Efficient Fine-Tuning (PEFT) methods for few-shot Natural Language Generation (NLG), which freeze most parameters in LLMs and tune a small subset of parameters in few-shot cases so that memory footprint, training cost, and labeling cost are reduced while...
NeMo 2.0 introduces a complete overhaul of Parameter Efficient Fine-Tuning (PEFT). The new design formulates PEFT as a Model Transform that freezes the base model and inserts trainable adapters at specific locations within the model.The following section describes the hierarchy of class objects....
Then, we formulate the reasoning process of LLMs into a causal framework, which provides a formal explanation of the problems observed in the visualization. Finally, building upon this causal framework, we propose Deconfounded Causal Adaptation (DCA), a novel parameter-efficient fine-tuning (PEFT)...
