Region-based classification of PolSAR data using radial basis kernel functions with stochastic distances
Region-based classification of PolSAR data can be effectively performed by seeking for the assignment that minimizes a distance between prototypes and segments. Silva et al. [“Classification of segments in PolSAR imagery ...
Constructions of rotated lattice constellations in dimensions power of 3
In this paper, we present the constructions of rotated ℤ3r-1-lattices, where r is a positive integer, via ℤ-modules of the ring of the integers ℤ [ζ3r+ζ 3r-1]. Our focus is on totally real number fields since the associated ...
Constructions of ideal lattices with full diversity
In this paper, we present new constructions of ideal lattices for the Rayleigh fading channel in Euclidean spaces with full diversity. These constructions are through totally real subfields of cyclotomic fields, obtained ...
MINIMUM DISTANCE ESTIMATION OF ARFIMA PROCESSES
(NORTH HOLLAND, 2013)
Probabilistic OWA distances applied to asset management
Average distances are widely used in many fields for calculating the distances between two sets of elements. This paper presents several new average distances by using the ordered weighted average, the probability and the ...
ON THE ORDER BOUNDS FOR ONE-POINT AG CODES
(Amer Inst Mathematical SciencesSpringfieldEUA, 2011)
Commutative group codes in R4, R6, R8 and R16-Approaching the bound
Spherical codes in even dimensions n = 2m generated by a commutative group of orthogonal matrices can be determined by a quotient of m-dimensional lattices when the sublattice has an orthogonal basis. We discuss here the ...
Adaptive computation of the swap-insert correction distance
(Association for Computing Machinery, 2018)
The Swap-Insert Correction distance from a string S of length n to another string L of length m≥n on the alphabet [1.δ] is the minimum number of insertions, and swaps of pairs of adjacent symbols, converting S into L. ...
Distance measures, weighted averages, OWA operators and Bonferroni means
The ordered weighted average (OWA) is an aggregation operator that provides a parameterized family of operators between the minimum and the maximum. This paper presents the OWA weighted average distance operator. The main ...
