Jang-Hyun Kim
Hello!
I am a PhD student in computer science at Seoul National University, advised by Hyun Oh Song.
I am currently at New York University as a visiting scholar, hosted by Kyunghyun Cho (~2024.08).
I previously interned at NAVER CLOVA
AI in 2018,
working on speech enhancement and speaker verification.
I completed my Bachelors with Mathematics at Seoul National University in 2019.

Research
My research focuses on developing a robust and efficient machine learning system in the real-world
through a data-centric approach that capitalizes on the redundancy in data:
- [Generation] How can we generate effective training data with minimal human intervention?
This prompts exploration into saliency-based data augmentation strategies
[Puzzle Mix,
Co-Mixup].
- [Compression] What is the extent of information embedded in the dataset/context?
This motivates research on constructing a condensed training dataset or context memory
[Context Memory,
Data Parameterization,
Spherical Principal Curves].
- [Identification] How can we identify diverse problems in the real-world data?
This leads to a project on identification of problematic data using the relational structure of
data
[Neural Relation Graph].
