YOUNGJUN CHOI
Research Engineer
Youngjun Choi is a
second-year PhD student at TX Lab, KAIST, advised by Prof. Jinjoon Lee. His
research focuses on the intersection of aesthetics and human-computer
interaction, particularly in the theme of landscape, AI and multisensory
experiences. He’s interested in enriching the
discourse on how digital interfaces can be leveraged to create immersive
exhibitions, thereby expanding the boundaries of artistic expression and
audience engagement.
Works
Participated in the
exhibition ‘Audible Garden’ as a creative developer responsible for algorithmic
composition and sound design. He developed a novel data sonification and
visualization framework that transcodes physical objects into multisensory
outputs. This interdisciplinary approach has also been the subject of academic
output, with the work being submitted to Leonardo | MIT Press, as the first
author (currently under review).
Micro-variation of Sound Objects Using Component Separation and Diffusion Models
Choi, Y., Liu, P., & Lee. J. Micro-variation of Sound Objects Using Component Separation and Diffusion Models. ICMC. 2023.
Introduced
a novel method for resynthesizing sound objects using component separation
techniques and deep neural networks called diffusion models. It offers a unique
approach to achieving sophisticated, non-deterministic variations in sound
characteristics, enhancing digital sound design and music composition. This
innovative technique opens up new possibilities for artists and engineers in
creating rich, varied soundscapes and patterns. This work was presented at the
International Computer Music Conference (ICMC) 2023 as co-first author.
Cartography of Urban Ambience
Conducted
an speculative practice of merging map-making with environmental sound
analysis, underscoring the integration of multimedia analysis on cartography.
It effectively captures the identity of urban environments, arousing further
curiosity about different districts by imagining the ambience through colors.
He has submitted this work as the first author of a full paper to the
International Symposium of Electronic Arts (ISEA) 2024 (currently under
review).
