Day 1:
Artificial Intelligence (AI) Solutions for Computational and Materials Chemistry Tasks
Olexandr Isayev
Department of Chemistry, Carnegie Mellon University
Abstract:
Deep learning is revolutionizing many areas of science and technology, particularly in natural language processing, speech recognition, and computer vision. In this talk, we will provide an overview of the latest developments in machine learning and AI methods and application to the problem of molecular design at Isayev’s Lab at CMU. We identify several areas where existing methods have the potential to accelerate computational chemistry research and disrupt more traditional approaches. First, we will present a deep learning model that approximates the solution of the Schrodinger equation. Focusing on parametrization for organic and element-organic molecules, we have developed a single ‘universal’ model, which is highly accurate compared to reference quantum mechanical calculations at speeds 10^6 faster. These models accurately represent the underlying physical chemistry of molecules through various test cases, including chemical reactions (thermodynamics and kinetics), thermochemistry, structural optimization, and molecular dynamics simulations. The results presented in this talk will provide evidence of the universal applicability of deep learning potentials to various chemistry problems involving organic molecules.
Second, we proposed a novel ML-guided materials discovery platform that combines synergistic innovations in automated flow synthesis and automated machine learning (AutoML) method development. A software-controlled, continuous polymer synthesis platform enables rapid iterative experimental–computational cycles that result in the synthesis of hundreds of unique copolymer compositions within a multi-variable compositional space. The non-intuitive design criteria identified by ML, accomplished by exploring less than 1% of overall compositional space, upended conventional wisdom in the materials design. We are currently enhancing this platform with Reinforcement learning (RL) agents. Under the RL paradigm, an agent(s) is trained to select actions that maximize the cumulative sum of rewards, which, in the context of chemical discovery, is often consistent with a target property, structural feature, or function. By training via value-based or policy-based iterative schemes, RL agents can learn to suggest synthesis protocols, potential reactants, and experimental conditions.
Day 2:
Physical (and AI/ML amenable) paradigms for computationally interrogating atomic scale reaction mechanisms
John A. Keith
Department of Chemical and Petroleum Engineering, University of Pittsburgh
This talk will provide an overview of our group’s recent work in understanding and developing computational chemistry methods to elucidate atomic scale chemical reaction mechanisms across chemical compound space. I will show work describing calculation schemes that use quantum alchemy for computational catalysis, atomic properties, and bond energy predictions. I will also describe progress toward the development of Bond Energy from Bond Orders and Populations (BEBOP) methods, classes of semi-empirical methods that can provide a) approximate atomization energies based on interatomic bond energy decompositions and b) approximate zero-point energies, and more, all based on just one single quantum chemistry calculation for high quality orbital populations. Outlook for improving all these methods’ accuracy, lowering their computational cost, and extending their usefulness across chemistry and materials science will be discussed.
Day 3:
Combining Advanced Simulations and Experiments: A Path Toward Understanding Collective Phenomena
Erik Luijten
Department of Materials Science and Engineering, Northwestern University
In this lecture, I will describe how advances in computational materials science permit new insights into collective phenomena. Notably, I will discuss close collaborations between simulation and experiment that have resulted in significant progress in nanoparticle crystallization, tunable supramolecular hierarchical self-assembly, and colloidal aggregation phenomena.
