Central quantile subspace [PDF]

Statistics and Computing, 2019
Quantile regression (QR) is becoming increasingly popular due to its relevance in many scientific investigations. There is a great amount of work about linear and nonlinear QR models. Specifically, nonparametric estimation of the conditional quantiles received particular attention, due to its model flexibility.

Quality-Driven Kernel Projection to Latent Structure Model for Nonlinear Process Monitoring

IEEE Access, 2019
A novel quality-driven kernel projection to latent structure (QKPLS) modeling scheme is proposed for concurrent quality-related and process-fault detection for nonlinear processes.

Projection subspace clustering

Journal of Algorithms & Computational Technology, 2017
Gene expression data is a kind of high dimension and small sample size data. The clustering accuracy of conventional clustering techniques is lower on gene expression data due to its high dimension.

Subspaces and graphs [PDF]

Proceedings of the American Mathematical Society, 1993
Subspaces sufficiently near an arbitrary (fixed) subspace of a Hilbert space are shown to be in one-to-one correspondence with operators defined on the given subspace. Specifically, the nearby subspaces can be regarded as the graphs of these operators. This is applied to explicitly define a C ∞ {C^\infty

On Grothendieck Subspaces [PDF]

Siberian Mathematical Journal, 2005
The modulus of an order bounded functional on a Riesz space is the sum of a pair of Riesz homomorphisms if and only if the kernel of this functional is a Grothendieck subspace of the ambient Riesz space. An operator version of this fact is given.

Lie Triple Derivations on 𝒥-Subspace Lattice Algebras

Abstract and Applied Analysis, 2014
We describe the structure of Lie triple derivations on 𝒥-subspace lattice algebras. The results can be applied to atomic Boolean subspace lattice algebras and pentagon subspace lattice algebras, respectively.
