About me

I’m a Ph.D student of Efficient Computing Lab in the Computer Science & Engineering depeartment at the POSTECH, South Korea.

My main research interest mostly focuses on designing acceleration systems for AI to enable people to take full advantage of AI. Also, I’m interested in core computer vision problems such as representation learning and diffusion model. In particular, I’m interested in the following topics.

• Neural Network Compression
  • Quantization ( NeurIPS23 , CVPR23 ) ,
  • Pruning( CODES+ISSS21).
  • Feature Reusing ( Arxiv23 )
• Computer Systems
  • GPGPU Kernel (CODES+ISSS21)
• Vision
  • Diffusion Model ( NeurIPS23, Arxiv23 )
  • Multi modal learning (Vision + Language) ( NeurIPS23, IEEE Access23 )
