Ardian Umam

Short bio

My name is Ardian Umam (禹安銳), you can call me Ardian, or 安銳 (An-Rui) in Chinese. I am currently pursuing my Ph.D. in the Department of Electrical Engineering and Computer Science at National Yang Ming Chiao Tung University, Taiwan, working with Prof. Yen-Yu Lin from VLLab and Prof. Jen-Hui Chuang from Islab.

My reseach interests lie in (but not limited to) deep learning, computer vision and multi-modal AI. Over the past 8 years, I have been working on various topics which involve 1D data (audio and languange), 2D data (image) and 3D data (point cloud and mesh). The tasks include audio quality estimation, optical character recognition, camera calibration, 3D point cloud augmentation, 3D segmentation, unsupervised/weakly supervised segmentation, and multi-modal (vision-language) recognition. Additionally, I interned at Google with the ChromeOS Audio Team and at ITRI working on model compression.
