Dong Hu(胡栋)

I will be graduating 2024 Summer and I am currently looking for jobs.

I am currently a final-year PhD student in computer science at Rensselaer Polytechnic Institute, advised by Prof. Alex Gittens. In the summer of 2020, I joined the RPI-IBM Artificial Intelligence Research Collaboration(AIRC) program as a scholar, under the supervision of Shashanka Ubaru and Lior Horesh.

Research Interest

My research focuses on using randomized linear algebra(RandNLA) tools to quantifiably trade off accuracy with computation time. My work lies in obtaining low-rank approximations for ML models(e.g. Matrix completion, Tensor Decomposition). I am also curious about exploring the possibilities of leveraging these RandNLA techniques in Deep Learning settings.

Here is my CV.

Misc. interests

I love traveling and taking photos. Most of my recent photography work is done using either medium format or large format film cameras. You can find most of my works (in low resolution) on my instagram account. You can always reach out to me to acquire the raw files for archival-quality prints.

I also engage in Texas Hold’em poker during my free time, playing both online and offline. I am a profitable poker player at GGpoker(NL200 Zoom level).
