Scaling rank-one updating formula and its application in unconstrained optimization
… estimate. Numerical tests show that the new method compares favourably with BFGS. Using the OCSSRl update, we propose a hybrid QN algorithm which does not need to store any matrix. Numerical results show that it is a very promising method for solving large scale optimization problems. In …

Progress on the Interplay of Machine Learning and Optimization
… In Chapter 4, we propose an integer optimization method to improve class-imbalanced data. Our method undersamples the majority class and performs better than existing methods on real-world imbalanced datasets. In the second part of the thesis, we explore the direction of applying machine learning …

Methods for the integrated design of viscoelastic materials and structural geometry
… dissertation research presents integrated design methodologies for the system-level performance-driven design of structural geometry and viscoelastic material properties. By relaxing unnecessary assumptions and optimizing system-level performance by searching the rich spectrum of possible design …
