Ce qui se cache derrière le fonctionnement de ChatGPT
ScienceEtonnante・2 minutes read
ChatGPT is a sophisticated chatbot using machine learning but faces challenges in creating effective conversations due to data limitations. The model's responses are based on training data, lacking the ability to recall past information or source citations accurately.
Insights
- ChatGPT, a chatbot based on GPT models, uses self-supervised learning to generate responses, predicting the next word in text to create plausible continuations without a universal truth, allowing for billions of training examples without human annotations.
- GPT models like GPT3 have vast parameters and context window sizes, with GPT4 potentially having even more extensive capabilities, recalling information from thousands of words earlier, but lacking memory of past conversations and providing responses based on associations rather than truth, highlighting the need for preprompts to guide responses and the challenge of accuracy in citing sources.
