Research Interests
I am xinwang liu. My research interest includes machine Learning, data mining, and computer vision. More indtail, I have done research on supervised learning and kernel learning. I have interest in how to build efficient and effective supervised learning models, which often involves non-convex optimization problems. I also have strong interest in multiple kernel learning, which involves a convex-concave optimization. I devote myself to design effective and efficient optimization methods to solve these machine learning problems. Furthermore, I also have interest in online learning and unsupervised learning.
