Research Group

We conduct research in the field of Artificial Intelligence, focusing on deep learning methodologies from foundational studies to practical applications, with an emphasis on perception (recognition), reasoning, and generative models. Particularly, we aim to develop simple yet effective approaches that are easily understandable without complex knowledge and readily implementable without complicated algorithms, enabling widespread adoption.

Join Our Group!

We are continually seeking highly motivated students at both undergraduate and graduate levels for full-time and part-time positions. Compensation will be based on the applicant's skill set and contributions. Priority areas include Neurosymbolic (Logical) Neural Networks and Multimodal Deep Models. The application can be sent to y.kim AT inha.ac.kr.
