Neural Ordinary Differential Equation Model for Evolutionary Subspace Clustering and Its Applications

no code implementations22 Jul 2021 Mingyuan Bai, S. T. Boris Choy, Junping Zhang, Junbin Gao

In this paper, we propose a neural ODE model for evolutionary subspace clustering to overcome this limitation and a new objective function with subspace self-expressiveness constraint is introduced.

Coupling Matrix Manifolds and Their Applications in Optimal Transport

no code implementations15 Nov 2019 Dai Shi, Junbin Gao, Xia Hong, S. T. Boris Choy, Zhiyong Wang

These geometrical features of CMM have paved the way for developing numerical Riemannian optimization algorithms such as Riemannian gradient descent and Riemannian trust-region algorithms, forming a uniform optimization method for all types of OT problems.

Tensor-Train Parameterization for Ultra Dimensionality Reduction

no code implementations14 Aug 2019 Mingyuan Bai, S. T. Boris Choy, Xin Song, Junbin Gao

Thus, we propose a tensor-train parameterization for ultra dimensionality reduction (TTPUDR) in which the traditional LPP mapping is tensorized in terms of tensor-trains and the LPP objective is replaced with the Frobenius norm to increase the robustness of the model.
