Generative Pre-trained Transformer
The Generative Pre-trained Transformer (GPT) is a type of deep learning model used for natural language processing (NLP) tasks. It was developed by OpenAI and is based on the transformer architecture. GPT is pre-trained on massive amounts of text data and can generate human-like text, complete sentences, paragraphs, or even entire articles.
The GPT models are unsupervised and learn by predicting the next word or sequence of words based on the context of the previous words in the sentence. The pre-training process involves two main steps: unsupervised pre-training and supervised fine-tuning.
In the unsupervised pre-training step, the model is trained on a large corpus of text data using a task called language modeling. This involves predicting the likelihood of the next word in a sequence given the previous words. The model is trained to generate coherent and meaningful sentences by predicting the most likely next word based on the context of the previous words.
In the supervised fine-tuning step, the pre-trained model is fine-tuned on a specific task such as sentiment analysis, machine translation, or question answering. The fine-tuning process involves training the model on a smaller dataset with labeled examples.
The GPT models have achieved state-of-the-art performance on various NLP tasks, including language modeling, text generation, and question answering. They are widely used in industry and academia for various NLP applications.
