Robust sparse coding for one-class classification based on correntropy and logarithmic penalty function

Pattern Recognition, 2021
Abstract Similar to binary and multi-class classifiers, one-class classifiers have to face the difficulty of ’curse of dimensionality’ when they are applied to deal with high-dimensional samples. As an efficient dimensionality reduction method, sparse coding tries to learn a set of over-complete bases to represent the given samples.

Exact Penalty Function and Asymptotic Strong Nonlinear Duality in Integer Programming

Acta Mathematicae Applicatae Sinica, 2004
In this paper, a logarithmic-exponential penalty function with two parameters for integer programming is discussed. We obtain the exact penalty properties and then establish the asymptotic strong nonlinear duality in the corresponding logarithmic ...

Logarithmic-exponential penalty formulation for integer programming

Applied Mathematics Letters, 1999
The purpose of this note is to present a smooth penalty formulation for integer programming. By adopting the proposed logarithmic-exponential penalty function, we are able to transform an inequality constrained integer programming problem into an ...

A New Exact Penalty Function Approach to Semi-infinite Programming Problem

, 2014
In this paper, we propose a new exact penalty function method for solving a class of semi-infinite programming problems (SIPs). We introduce a logarithmic form function of the constraint violation, where the constraint violation is a measure of the ...

A penalty method for nonparametric estimation of the logarithmic derivative of a density function

Annals of the Institute of Statistical Mathematics, 1985
This paper deals with the estimation of the function \(\psi_ 0=-f'\!_ 0/f_ 0\) from independent random variables \(X_ 1,...,X_ n\) with common unknown density \(f_ 0\) and cumulative distribution function \(F_ 0\). From the remark that, under mild conditions, \(\psi_ 0\) is the unique minimizer of \(\int [\psi^ 2-2\psi ']dF_ 0\) the author proposes as ...
