This lecture introduces the CAT+ project at EPFL, focusing on the development of intelligent systems for chemistry. Dr. Pascal Miéville explains the use of AI and ML tools in catalysis, showcasing examples of homogeneous and heterogeneous catalysis. The lecture covers the generation of new catalysts, optimization processes, and the integration of AI in chemistry research. It also discusses the challenges of data structure in spectroscopic analysis and the communication gap between chemists and AI experts.
