- A. PEFT does not modify any parameters but uses soft prompting with unlabeled data. PEFT modifies
- B. PEFT modifies all parameters and uses unlabeled, task-agnostic data.
- C. PEFT parameters and b typically used when no training data exists.
- D. PEFT involves only a few or new parameters and uses labeled, task-specific data.
Answer: D
Explanation:
Parameter-Efficient Fine-Tuning (PEFT) is a technique used in large language model training that focuses on adjusting only a subset of the model's parameters rather than all of them. This approach involves using labeled, task-specific data to fine-tune new or a limited number of parameters. PEFT is designed to be more efficient than classic fine-tuning, which typically adjusts all the parameters of the model. By only updating a small fraction of the model's parameters, PEFT reduces the computational resources and time required for fine-tuning while still achieving significant performance improvements on specific tasks.
