I am a master student in the Cognitive Learning for Vision and Robotics (CLVR) Lab at KAIST, advised by Joseph Lim. I received B.S. degree by double majoring both Computer Science and Engineering & Mathematics at POSTECH, where I could fortunately work with Dongwoo Kim, Jaesik Park, and Wankyun Chung.

I'm interested in understanding the fundamental principles of intelligence and building AI for invention. My research interests lie in domain generalization, structured representation learning, and deep generative models. Currently, I am working on the method of helping AI agents to understand a structure of its behaviors and to generate its own objectives. I hope the machine for invention being used for making universe exploring robots, creating the time machine, and dealing with all matters! :)

GM-VAE: Representation Learning with VAE on Gaussian Manifold
Seunghyuk Cho, Juyong Lee, Dongwoo Kim
JKAIA (Awarded), 2022

From the observation that the set of the diagonal Gaussian distributions with the Fisher information metric forms a product hyperbolic space (we name Gaussian manifold), we propose a variational auto-encoder whose latent space is the Gaussian manifold.

paper / code

A simple yet effective alteration of a hyperbolic wrapped normal distribution (HWN), to better utilize the geometric properties of the diagonal HWN. We analyze the geometric properties of the diagonal HWN and alleviate the limitation by introducing the rotated hyperbolic wrapped normal distribution (RoWN).

Style-Agnostic Reinforcement Learning

paper / code

Style-agnostic reinforcement learning algorithm, with the aim of both neural style transfer and adversarial learning. The style, here, refers to task-irrelevant details in the image, such as the background color. We let agents to learn style-agnostic representation by generating adversarial perturbation in the latent space and to show generalized performances.

A novel treatment for volumetric muscle loss with decellularized extraceullar matrix bioink using 3D cell printing technology. I, especially, participated in situ functional analysis of the 3D printed muscle cell, to electrically stimulate the peroneal nerve of mice legs. The results verifies that a 3D cell printing approach could effectively generate biomimetic engineered muscles to improve the treatment.
