Second-Order Cone Programming Formulations for Robust Multiclass Classification [PDF]

open access: yesNeural Computation, 2007
Multiclass classification is an important and ongoing research subject in machine learning. Current support vector methods for multiclass classification implicitly assume that the parameters in the optimization problems are known exactly. However, in practice, the parameters have perturbations since they are estimated from the training data, which are

Feature Scaling via Second-Order Cone Programming [PDF]

open access: yesMathematical Problems in Engineering, 2016
Feature scaling has attracted considerable attention during the past several decades because of its important role in feature selection. In this paper, a novel algorithm for learning scaling factors of features is proposed. It first assigns a nonnegative scaling factor to each feature of data and then adopts a generalized performance measure to learn ...

Efficient Hyperkernel Learning Using Second-Order Cone Programming [PDF]

open access: yesIEEE Transactions on Neural Networks, 2004
The kernel function plays a central role in kernel methods. Most existing methods can only adapt the kernel parameters or the kernel matrix based on empirical data. Recently, Ong et al. introduced the method of hyperkernels which can be used to learn the kernel function directly in an inductive setting. However, the associated optimization problem is a

Calibration-Free Robot-Sensor Calibration approach based on Second-Order Cone Programming

open access: yesMATEC Web of Conferences, 2018
In order to overcome the restrictions of traditional robot-sensor calibration method which solve the tool-camera transformation and robot-world transformation rely on calibration target, a calibration-free approach that solve the robot-sensor calibration

Second-Order Cone Relaxations for Binary Quadratic Polynomial Programs [PDF]

open access: yesSIAM Journal on Optimization, 2011
Several types of relaxations for binary quadratic polynomial programs can be obtained using linear, second-order cone, or semidefinite techniques. In this paper, we propose a general framework to construct conic relaxations for binary quadratic polynomial programs based on polynomial programming.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Nonsingularity Conditions for FB System of Reformulating Nonlinear Second-Order Cone Programming

open access: yesAbstract and Applied Analysis, 2013
This paper is a counterpart of Bi et al., 2011. For a locally optimal solution to the nonlinear second-order cone programming (SOCP), specifically, under Robinson’s constraint qualification, we establish the equivalence among the following three ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Efficient Solutions of Interval Programming Problems with Inexact Parameters and Second Order Cone Constraints

open access: yesMathematics, 2018
In this article, a methodology is developed to solve an interval and a fractional interval programming problem by converting into a non-interval form for second order cone constraints, with the objective function and constraints being interval valued ...
