Research Experience & Projects
Master 2 Internship
IRMAR & INSA Rennes
- Master 2 Thesis: Complementarity problems and absolute value equations: Analysis and comparison of numerical methods
- Advisors: Prof. Mounir Haddou and Prof. Dominique Monnet
- Abstract: We analyse and compare several numerical approaches and also consider generalizations of linear absolute value problems to nonlinear ones.
Master 2 Projects
HCMC University of Science (HCMUS)
- Comparison of opmitization methods: Studied and compared a range of optimization algorithms including (proximal) gradient descent, the (proximal) heavy ball method, ISTA, and FISTA.
- Modelisation and scientific computing: Implemented 1D finite difference and 2D finite element methods to solve PDEs applied to mechanical problems.
Graduation Thesis
HCMC University of Education
- Thesis: Subgradient Method and Applications — Grade: 10/10
- Advisors: Prof. Tran Ba Dat and Prof. Pham Duy Khanh
- Abstract: The thesis studies the convergence analysis of different variants of Shor’s subgradient method. The algorithms are then applied to solve Lasso regression and Convex clustering problems with real data sets via Python.
Scientific Project
HCMC University of Education
- Topic: Projection Methods for Solving Generalized Monotone Variational Inequalities
- Advisor: Prof. Pham Duy Khanh
- Third prize in Scientific Research Conference for Undergraduates in academic year 2021–2022.
- Abstract: We studied the theory of generalized monotone variational inequalities and projection methods for solving them.
Summer School Project (for selected students)
HCMC University of Education
- Topic: Linear Support Vector Machines
- Advisor: Prof. Tran Thai An Nghia
- Abstract: We trained and tested a linear SVM model based on two real data sets by using the subgradient method as well as writing and solving its dual problem.
