“What’s wrong with LLMs and what we should be building instead” - Tom Dietterich - #VSCF2023

Thomas G. Dietterich is emeritus professor of computer science at Oregon State University. He is one of the pioneers of the field of machine learning. He served as executive editor of the journal called Machine Learning (1992–98) and helped co-found the Journal of Machine Learning Research. He is one of the members of our select valgrAI Scientific Council. Keynote: “What’s wrong with LLMs and what we should be building instead” Abstract: Large Language Models provide a pre-trained foundation for training many interesting AI systems. However, they have many shortcomings. They are expensive to train and to update, their non-linguistic knowledge is poor, they make false and self-contradictory statements, and these statements can be socially and ethically inappropriate. This talk will review these shortcomdifferentings and current efforts to address them within the existing LLM framework. It will then argue for a , more modular architecture that decomposes the functions of existing LLMs and adds several additional components. We believe this alternative can address all of the shortcomings of LLMs. We will speculate about how this modular architecture could be built through a combination of machine learning and engineering.
