Redefining support vector machines with the ordered weighted average
In this work, the classical soft-margin Support Vector Machine (SVM) formulation is redefined with the inclusion of an Ordered Weighted Averaging (OWA) operator. In particular, the hinge loss function is rewritten as a ...
Limit cycles bifurcating from the periodic annulus of the weight-homogeneous polynomial centers of weight-degree 2
We obtain an explicit polynomial whose simple positive real roots provide the limit cycles which bifurcate from the periodic orbits of a family of cubic polynomial differential centers when it is perturbed inside the class ...
Weighted norm inequalities for vector-valued singular integrals on homogeneous spaces
(Polish Acad Sciences Inst MathematicsWarsawPolónia, 2004)
Polynomial Differential Systems in R3 Having Invariant Weighted Homogeneous Surfaces
In this paper we give the normal form of all polynomial differential systems in R3 having a weighted homogeneous surface f= 0 as an invariant algebraic surface and characterize among these systems those having a Darboux ...
Vector-valued extensions of operators on martingales

Structural stability of planar quasihomogeneous vector fields
(SpringerBirkhäuser BaselDordrecht, 2014-04)
Let 'H IND.PQM' be the space of all planar (p,q)-quasihomogeneous vector fields of weight degree m endowed with the coefficient topology. In this paper we characterize the set 'Ω IND.PQM' of all vector fields in 'H IND.PQM' ...
Long-term inhibition of ethanol intake by the administration of an aldehyde dehydrogenase-2 (ALDH2)-coding lentiviral vector into the ventral tegmental area of rats
(Society for the Study of Addiction, 2014)
Previous studies suggest that acetaldehyde generated from ethanol in the brain is reinforcing. The present studies tested the feasibility of achieving a long-term reduction of chronic and post-deprivation binge ethanol ...
Weight vector estimation of circular arrays of antennas using Artificial Neural Networks
This paper presents a model for the control of the radiation pattern of a circular array of antennas, shaping it to address the radiation beam in the direction of the user, in order to reduce the transmitted power and to ...
