Optimal control theory for a unitary operation under dissipative evolution

open access: yesNew Journal of Physics, 2014
We show that optimizing a quantum gate for an open quantum system requires the time evolution of only three states irrespective of the dimension of Hilbert space. This represents a significant reduction in computational resources compared to the complete

Adaptive Reduction of Curse of Dimensionality in Nonparametric Instrumental Variable Estimation

open access: yesMathematics
Nonparametric estimation of instrumental variable treatment effects typically builds on various nonparametric identification results. However, these estimators often face challenges from the curse of dimensionality in practice, as multi-dimensional ...

Integrated multidimensional analysis is required for accurate prognostic biomarkers in colorectal cancer.

open access: yesPLoS ONE, 2014
CRC cancer is one of the deadliest diseases in Western countries. In order to develop prognostic biomarkers for CRC (colorectal cancer) aggressiveness, we analyzed retrospectively 267 CRC patients via a novel, multidimensional biomarker platform.

RMFGP: A Rotated Multi-Fidelity Gaussian Process Framework for Supervised Dimension Reduction

open access: yesMathematics
High-dimensional surrogate modeling with limited high-fidelity data poses a major challenge in uncertainty quantification. Classical supervised dimension reduction methods often fail in this setting due to insufficient accurate observations, while low ...

Sufficient Dimension Reduction for Classification

open access: yesStatistica Sinica
We propose a new sufficient dimension reduction approach designed deliberately for high-dimensional classification. This novel method is named maximal mean variance (MMV), inspired by the mean variance index first proposed by Cui, Li and Zhong (2015), which measures the dependence between a categorical random variable with multiple classes and a ...

Condition Assessment of PCI Bridge Girder a Result of The Reduction Prestressing Force

open access: yesEPJ Web of Conferences, 2014
PCI bridge girders is known and widely used for many construction e.g.: bridge, wharf, flyover, and other application. PC Bridge girders have two types: Pre - tensioned girders and post - tensioned girders.

Multivariate response directional regression: a projective resampling approach

open access: yesJournal of Big Data
In high dimensional data analysis, directional regression is a widely used method for implementing linear sufficient dimension reduction by extracting core information from the complex data structure.
