Wavelet Tree Ensembles for Triangulable Manifolds
Hengrui Luo, Akira Horiguchi, Li Ma
We develop unbalanced Haar (UH) wavelet tree ensembles for regression on triangulable manifolds. Given data sampled on a triangulated manifold, we construct UH wavelet trees whose…

Efficient Decision Trees for Tensor Regressions
Hengrui Luo, Akira Horiguchi, Li Ma
We proposed the tensor-input tree (TT) method for scalar-on-tensor and tensor-on-tensor regression problems. We first address scalar-on-tensor problem by proposing scalar-output re…

Stream-level flow matching with Gaussian processes
Ganchao Wei, Li Ma
Flow matching (FM) is a family of training algorithms for fitting continuous normalizing flows (CNFs). Conditional flow matching (CFM) exploits the fact that the marginal vector fi…
