Yu Liu (刘宇)

I'm Yu Liu, a senior undergraduate student in Department of Automation, Tsinghua University. I joined the Tong Class (an AGI program founded by Prof. Song-Chun Zhu), being a member and the monitor in the class of 2020. I'm currently working at General Vision Lab in BIGAI (Beijing Institute for General Artificial Intelligence) as a research intern advised by Dr. Baoxiong Jia and Dr. Siyuan Huang.

My research interest lies in computer vision, specifically unsupervised object-centric learning. My hobbies are reading, music, natural scenery and meditation.

Improving Object-centric Learning With Query Optimization
Baoxiong Jia*, Yu Liu*, Siyuan Huang,

[Paper]   [Project Page]   [Code]
We proposed methods for (1) initializing Slot-Attention modules with learnable queries and (2) optimizing the model with bi-level optimization. With simple code adjustments on the vanilla Slot-Attention, our model, Bi-level Optimized Query Slot Attention, achieves state-of-the-art results on 3 challenging synthetic and 7 complex real-world datasets in unsupervised image segmentation and reconstruction, outperforming previous baselines by a large margin.
