Inside GPT – Large Language Models Demystified • Alan Smith • GOTO 2024

This presentation was recorded at GOTO Amsterdam 2024. #GOTOcon #GOTOams https://gotoams.nl Alan Smith - AI Developer, Trainer, Mentor & Evangelist at Active Solution @CloudCastsAlanSmith RESOURCES https://twitter.com/alansmith https://www.linkedin.com/in/alan-smith-68a8491 ABSTRACT Natural language processing using generative pre-trained transformers (GPT) algorithms is a rapidly evolving field that offers many opportunities and challenges for application developers. But what is a generative pre-trained transformer, and how does it work? How can you leverage the latest advances in GPT algorithms to create engaging and useful applications? Can my business benefit from creating a GPT powered chat bot? In this demo intensive session Alan will take a deep dive into the architecture of GPT algorithms and the inner workings of ChatGPT. The journey will begin by looking at the fundamental concepts of natural language processing, such as word embedding, vectorization and tokenization. He will then demonstrate how you can apply these techniques to train a GPT2 model that can generate song lyrics, showing the internals of how word sequences are predicted. Alan will then shift the focus to larger language models, such as ChatGPT and GPT4, demonstrating their power, capabilities, and limitations. The use of hyperparameters such as temperature and frequency penalty will be explained and their effect on the generated output demonstrated. Join me for this session if you want to learn how to harness the power of GPT algorithms in your own solutions.
