Combined genetic algorithm optimization and regularized orthogonal least squares learning for radial basis function networks

open access: yes, 1999
The paper presents a two-level learning method for radial basis function (RBF) networks. A regularized orthogonal least squares (ROLS) algorithm is employed at the lower level to construct RBF networks while the two key learning parameters, the ...

Robust nonlinear model identification methods using forward regression

open access: yes, 2003
In this correspondence new robust nonlinear model construction algorithms for a large class of linear-in-the-parameters models are introduced to enhance model robustness via combined parameter regularization and new robust structural selective criteria ...

Quasi-complete Latin squares: construction and randomization

open access: yes, 1984
A general method for constructing quasi-complete Latin squares based on groups is given. This method leads to a relatively straightforward way of counting the number of inequivalent quasi-complete Latin squares of side at most 9.

On Graph-Orthogonal Arrays by Mutually Orthogonal Graph Squares

open access: yes, 2020
During the last two centuries, after the question asked by Euler concerning mutually orthogonal Latin squares (MOLS), essential advances have been made. MOLS are considered as a construction tool for orthogonal arrays.

A class of latin squares derived from finite abelian groups [PDF]

open access: yes, 2011
summary:We consider two classes of latin squares that are prolongations of Cayley tables of finite abelian groups. We will show that all squares in the first of these classes are confirmed bachelor squares, squares that have no orthogonal mate and ...

Three mutually orthogonal Latin squares [PDF]

open access: yes, 1972
In a famous paper [3], Bose, Shrikhande, and Parker proved the existence of a pair of orthogonal Latin squares of order v for all v ≠ 2,6. In the present paper it is shown that there exist three mutually orthogonal Latin squares for all v ≡ 0,1 (mod 4 ...

On the difference between orthogonal matching pursuit and orthogonal least squares

open access: yes, 2007
— Greedy algorithms are often used to solve underdetermined inverse problems when the solution is constrained to be sparse, i.e. the solution is only expected to have a relatively small number of non-zero elements.
