- 요약Machine learning (ML) methods have the potential to solve the longstanding challenge of discovering catalysts that can convert renewable energy to fuel, discovering molecules with desired properties, and discovering drugs as they are up to O(105) times faster than the conventional quantum mechanical (QM) simulators like Density Functional Theory (DFT). Graph Neural Networks (GNNs) have emerged as promising approximators of DFT but face challenges with generalization. Moreover, for a few simulations replacing DFT with GNNs is not sufficient to perform large-scale screening and requires the development of fundamentally novel approaches to accelerate simulations.This thesis explores advanced machine learning (ML) methodologies and frameworks for accelerating materials discovery, with a primary focus on heterogeneous catalysis. The research addresses challenges in large-scale ML applications within catalysis, examining out-of-distribution generalization, metrics, and methodological approaches. A novel transfer learning framework is proposed to improve the generalization of the model across atomic domains. While generalizable ML potentials significantly expedite catalyst simulation by substituting density functional theory (DFT), the thesis demonstrates that novel ML frameworks can further accelerate simulations. To this end, a GNN model is developed to efficiently learn and directly predict the optimal adsorbate-catalyst configurations. The research culminates in the development of a diffusion framework designed to accelerate adsorbate-catalyst optimization processes.
