I'm a senior machine learning developer in SAP, and a Ph.D. student advised by Prof. Sungjin Ahn at KAIST. Before that, I worked in Samsung Electronics and graduated from KAIST.

To extend the generality of AI, we've studied 

• learning-to-learn (a.k.a meta-learning or few-shot learning) [c2, p1, c3, c4],

• unsupervised learning of compositional representation such as object-centric representation [c5, c6],

• and agent learning incorporating episodic memory [w1].

I am interested in compositional representation which can be generally utilized for a large range of tasks like human intelligence.
