Shinhyeok Oh

I obtained a master’s degree in computer and communications engineering from the Kangwon National University, under the guidance of Prof. Harksoo Kim. I am currently working at 42dot as a Generative NLP Engineer, and enjoy discussing topics related to transfer learning and knowledge distillation. Specifically, I find pleasure in exploring ways, such as self-supervised learning, domain adaptation, and multi-modality, to extract value from other tasks, domains, or previously overlooked resources for the intended objective.
