Machine Learning Applications in Crystallography and Structural Science: A Review

What is it about?

The study presents a virtual collection of articles from the International Union of Crystallography (IUCr) journals focusing on the application of artificial intelligence (AI) and machine learning (ML) in crystallography and structural science. It introduces terms and concepts related to AI and ML, providing a brief history of their use in structural science as documented in IUCr journals. The methodology includes summarizing both the scientific targets and AI/ML methods used in each paper within the collection, allowing for easy navigation. The study categorizes the papers by ML and domain topics, aiming to highlight how these technologies have developed and are currently applied in crystallography. The research covers various types of ML, including unsupervised, supervised, and generative approaches, and differentiates between conventional ML methods and deep learning. The study notes the earliest AI publication in IUCr journals dated back to 1977, indicating a long-standing interest in applying AI to protein crystallography.
