초록/해제  
요약In recent years, the landscape of molecular science has been profoundly transformed by the integration of data-driven methodologies alongside traditional deterministic and stochastic approaches. Historically, the study of molecular behavior and interactions relied heavily on deterministic algorithms, which follow a fixed sequence of computational steps to simulate molecular dynamics, and stochastic simulations, which incorporate randomness to explore various molecular states and pathways. These methods were complemented by physical models grounded in the established principles of chemistry and physics, forming the backbone of theoretical molecular science. However, these conventional approaches often faced limitations in scalability, computational cost, and generalizability for complex systems. The improvements in computational hardware, coupled with the accumulation of vast amounts of molecular data, have enabled the development of models that can surpass traditional methods in both accuracy and efficiency, leveraging both physics-based and machine learning (ML) approaches. This dissertation focuses on the development of new models utilizing more accessible data, provides guidelines for computational data generation, and explores the synergy between data acquisition strategies and data-driven models. These studies demonstrate that by carefully designing data acquisition strategies and integrating data-driven models with physics-based approaches, it is possible to enhance the predictive capabilities of computational methods in chemistry, particularly in force field development and electrostatic modeling. Through a series of studies, this work illustrates the potential of combining the strengths of both traditional and modern computational techniques to achieve more accurate and efficient predictions in molecular science.
