About Me

Hi, I’m Jongsu Kim. I’m a Ph.D. in Computational Science and Engineering-Mechanical/Electrical Engineering qualified by a research background in machine learning and mathematical modeling focused on time series forecasting and computational fluid dynamics.

I can do mathematical or physical modeling numerically and have analytic skills for physical phenomenon. Not only modeling skills, I also have a strong computer science background and like to actively learn new technologies.

EXPERIENCE

Artifical Intelligence Professional

LG CNS

10/2021 ~ Present

  • Focused on multifaceted problem-solving to address diverse and complex challenges across various topics
  • Refined LLM training data and reduced training costs through a data-centric approach
  • Controlled false alarms by implementing anomaly detection tailored for digital transformation using limited factory equipment and vibration data
  • Managed a project to enhance the performance of unsupervised learning vision inspection models for detecting new defects
  • Improved system stability by leveraging AWS metrics for data-driven anomaly detection and false alarm control
  • Developed and deployed an end-to-end anomaly detection solution in a production environment

Ph.D. Student

School of Mathematical Computing, Yonsei University, South Korea

09/2011 ~ 08/2021

  • Particulate Matter (PM) forecasting by deep learning methods for time series forecasting (2018-2021)
  • Modeling and simulation of finite-size particles in homogeneous isotropic turbulence using psuedo-spectral methods and immersed boundary methods (2015-2018)
  • Modeling and simulation of finite-size droplets in laminar flows with gravity field using level set methods (2011-2015)
  • Communicate to support laboratory colleagues who was struggling with computer science-related problems such as algorithms, debugging, and so on. The process was then documented so that the next time the team encountered the same situation, they could follow a similar procedure.
  • Programming knowledge (mainly Julia, C++, Fortran)
  • Create web pages for multiple purposes in the department, such as conference, introduction pages, and so on.
  • Administrator of laboratory server (cluster with ~30 nodes)
