Hello, I’m Dong-Hee

👋 About Me

Hello, I'm Dong-Hee Shin, a Ph.D. student in Artificial Intelligence at Korea University, advised by Prof. Tae-Eui Kam. My main research interests are in molecular discovery, particularly in new drug discovery and novel material design. On the AI side, I focus on reinforcement learning and optimization algorithms to support scientific innovation.

Dynamic Many-Objective Molecular Optimization: Unfolding Complexity with Objective Decomposition and Progressive Optimization

Dong-Hee Shin, Young-Han Son, Deok-Joong Lee, Ji-Wung Han, Tae-Eui Kam

International Joint Conference on Artificial Intelligence (IJCAI), 2024

Lead oral presentation (12 min) | Top 2.2% (128 of 5,651 submissions)

• We propose a method for tackling dynamic many-objective molecular optimization problem by utilizing (1) objective decomposition and (2) progressive optimization.
  (1) Objective Decomposition: our method decomposes many-objective sets into more manageable sub-problems facilitated by our decomposition module.
  (2) Progressive Optimization: The optimization process begins with a single objective, then progressively adds subsequent objective in decomposition order.
