Probability-boosting technique for combinatorial optimization [PDF]

open access: yesPeerJ Computer Science
In many combinatorial optimization problems we want a particular set of k out of n items with some certain properties (or constraints). These properties may involve the k items.

Reduction of Phase Shifters in Planar Phased Arrays Using Novel Random Subarray Techniques

open access: yesApplied Sciences
Reducing the number of phase shifters by grouping antenna elements into subarrays has been extensively studied for decades. The number of phase shifters directly affects the cost, complexity, and power consumption of the system.

On Application of the Ray-Shooting Method for LQR via Static-Output-Feedback

open access: yesAlgorithms, 2018
In this article we suggest a randomized algorithm for the LQR (Linear Quadratic Regulator) optimal-control problem via static-output-feedback. The suggested algorithm is based on the recently introduced randomized optimization method called the Ray ...

Random forest missing data algorithms [PDF]

open access: yesStatistical Analysis and Data Mining: The ASA Data Science Journal, 2017
Random forest (RF) missing data algorithms are an attractive approach for imputing missing data. They have the desirable properties of being able to handle mixed types of missing data, they are adaptive to interactions and nonlinearity, and they have the potential to scale to big data settings.

Improved Generalized Cross-Validation and Unbiased Predictive Risk Estimator Methods Using the RGSVD: Application to Inversion of Potential Field Data

open access: yesApplied Sciences, 2021
The inversion of potential field data has widely utilized the generalized cross-validation (GCV) and the unbiased predictive risk estimator (UPRE) methods to determine the regularization parameter.

COARSE REDUCIBILITY AND ALGORITHMIC RANDOMNESS [PDF]

open access: yesThe Journal of Symbolic Logic, 2016
AbstractA coarse description of a set A ⊆ ω is a set D ⊆ ω such that the symmetric difference of A and D has asymptotic density 0. We study the extent to which noncomputable information can be effectively recovered from all coarse descriptions of a given set A, especially when A is effectively random in some sense.
