Teaching LLMs To Say “I don’t Know”

Cobus Greyling on LLMs, NLU, NLP, chatbots & voicebots • 0 implied HN points • 22 May 24
🕹 Technology Artificial Intelligence Natural Language Machine Learning Data science Reinforcement Learning
  1. Large Language Models (LLMs) often make up answers when they don't know something, which can lead to inaccuracies. Instead, it's better for them to say 'I don’t know' when faced with unfamiliar topics.
  2. LLMs can learn to give more accurate responses by being adjusted during training. They can be trained to recognize when they're unsure and respond cautiously instead of guessing.
  3. Using reinforcement learning approaches can help reduce these incorrect guesses or 'hallucinations' by teaching models to express uncertainty and limit their responses to what they truly know.
