33. Large Language Models in Materials Science

Welcome back to our Materials Informatics playlist! In today's episode, we explore the transformative impact of Large Language Models (LLMs) on materials science. David Sparks from the University of Utah's Materials Science and Engineering department takes us through the exciting possibilities that LLMs bring to the field. Here's a brief overview of what we'll cover: Introduction to Large Language Models (LLMs): Understanding their significance and historical context in AI and natural language processing. Pre-Neural Network NLP Techniques: Overview of methods like Bag of Words, Term Frequency-Inverse Document Frequency (TF-IDF), and N-Gram Models. Word Embeddings and Neural Networks: Introduction to Word2Vec, GloVe, and the evolution of embedding techniques. Modern LLM Architectures: The rise of transformers and notable milestones including GPT, BERT, T5, and XLNet. Reinforcement Learning from Human Feedback (RLHF): How this approach has improved the performance and reliability of LLMs. Challenges and Solutions: Addressing issues like hallucinations and token size limitations with techniques like Retrieval-Augmented Generation (RAG). Applications in Materials Science: Five key areas where LLMs are making an impact: data extraction, property prediction, generative models, automation, and education.
