Optimization on flag manifolds
Ke Ye, Ken Sze-Wai Wong, Lek-Heng Lim
A flag is a sequence of nested subspaces. Flags are ubiquitous in numerical analysis, arising in finite elements, multigrid, spectral, and pseudospectral methods for numerical PDE;…
The Grassmannian of affine subspaces
Lek-Heng Lim, Ken Sze-Wai Wong, Ke Ye
The Grassmannian of affine subspaces is a natural generalization of both the Euclidean space, points being zero-dimensional affine subspaces, and the usual Grassmannian, linear sub…
Macroeconomics and FinTech: Uncovering Latent Macroeconomic Effects on Peer-to-Peer Lending
Jessica Foo, Lek-Heng Lim, Ken Sze-Wai Wong
Peer-to-peer (P2P) lending is a fast growing financial technology (FinTech) trend that is displacing traditional retail banking. Studies on P2P lending have focused on predicting i…
Numerical algorithms on the affine Grassmannian
Lek-Heng Lim, Ken Sze-Wai Wong, Ke Ye
The affine Grassmannian is a noncompact smooth manifold that parameterizes all affine subspaces of a fixed dimension. It is a natural generalization of Euclidean space, points bein…
