We organize weekly AI meetings (KUIS AI Talks) both on zoom and in person. We hold these events every Tuesday from 11:30 am to 12:30 pm unless otherwise noted. We have guests from various universities and industries all over the world. Also, our graduate students present their progress some weeks. If you want to join us in these meetings, please email us at for the zoom info.

Efficient and Robust Learning on Non-Rigid Surfaces and Graphs

In this talk, I will describe several approaches for learning on curved surfaces undergoing non-rigid deformations. First, I will give a brief overview of intrinsic convolution methods, and then present a different approach based on learned diffusion. The key properties of this approach are its robustness to changes in discretization and efficiency in enabling long-range communication, both in terms of memory and time. I will then showcase several applications, ranging from RNA surface segmentation to non-rigid shape correspondence, and present a recent extension for learning on graphs.
