I am a senior undergraduate student in the Computer Science Department at National Tsing Hua University in Taiwan.

I am interested in improving the performance of Generative AI, focusing on training better models, building efficient and robust systems, and developing useful tools.

I'm currently working on two projects: HakuTPU and HomeDiffusion.
HakuTPU aims to build a high-performance AI accelerator based on Xilinx FPGA,
while HomeDiffusion seeks to enable pretrained diffusion models on consumer-level hardware.

AI art should look like AI, not humans.
