Research Abstract:

Due to the wide deployment of social networks and mobile devices, massive data is generated on the internet every second. Such big-data resources open new opportunities for artificial intelligence and machine learning, but meanwhile they also cause new challenges in data storage, representation, and computation. On the other hand, in many engineering designs obtaining data samples by measurement or numerical simulation is expensive, therefore people have to verify and optimize complex engineering designs with limited small data sets.
I have been working on computational techniques to address the challenges in both small- and big-data problems. Firstly, I have proposed a global optimization method for solving the non-convex tensor eigenvalue problem. Then, I have proposed a new uncertainty quantification framework with theoretical performance guarantees even if the input uncertainties are non-Gaussian correlated. Finally, I have studied the structural framework of DNN.
