  • Fill-Up: Balancing Long-Tailed Data with Generative Models (Under Review)
    Joonghyuk Shin, Minguk Kang, Jaesik Park
    We propose a two-stage training procedure for long-tailed recognition based on the fill-up operation with recent large-scale text-to-image synthesis models. During the Stage I, the image classifier is trained on balanced dataset, obtained by filling up long-tailed data with synthetic images from textual-inverted tokens. Stage II fine-tunes the image classifier with long-tailed real dataset along with Balanced Softmax loss. Our method achieves state-of-the-art results on standard long-tailed benchmarks when trained from scratch.

  • StudioGAN: A Taxonomy and Benchmark of GANs for Image Synthesis (TPAMI 2023)
    Minguk Kang, Joonghyuk Shin, Jaesik Park
    While training and evaluting GAN is becoming more and more important, the current GAN research ecosystem does not provide reliable benchmarks for fair and consistent evaluation. StudioGAN is a self-contained library that provides a vast number of GAN-related functionalities as modules, reproducing more than 30 popular GANs. We present extensive benchmarks of state-of-the-art GANs, following a suggested fair evaluation protocol, and open-source all the code and models.

I am a big fan of baseball. I played for POSTECH baseball team (Tachyons) for 5 years, as a captain and a catcher.
I love animals. I live with a dog named Poby. I also like Pokemon, travelling, and FIFA video games.
