Preferens- vs. promptdatamängder

Den fullständiga RLHF-processen med initial promptdatamängd och en preferensdatamängd som matas in i belöningsmodellen.

Promptdatamängd

  • Frågor till modellen
  • Finns på Hugging Face datasets
prompt_data = load_dataset("center-for-humans-and-machines/rlhf-hackathon-prompts", 
                           split="train")
prompt_data['prompt'][0]

'How important is climate change?'
  • Prompten kan behöva extraheras
  • Leta efter markörer som: Input=, {{Text}}:, ###Human:

Utforska preferensdatamängden

from datasets import load_dataset
preference_data = load_dataset("trl-internal-testing/hh-rlhf-helpful-base-trl-style", 
                               split="train")

Bearbeta preferensdatamängden

def extract_prompt(text):
    # Extract the prompt as the first element in the list
    prompt = text[0]["content"]
    return prompt

# Apply the extraction function to the dataset
preference_data_with_prompt = preference_data.map(
    lambda example: {**example, 'prompt': extract_prompt(example['chosen'])}
)
  • Hur promptar extraheras varierar mellan olika datamängder

Färdig preferensdatamängd

sample = preference_data_with_prompt.select(range(1))
sample['prompt']

'What vitamins are essential for the body to function?'

sample['chosen']

[ { "content": "What vitamins are essential for the body to function?", "role": 
   "user" }, { "content": "There are some very important vitamins that ensure the 
   proper functioning of the body, including Vitamins A, C, D, E, and K along ...}]
