Optimal probabilistic feature shifts for reclassification in tree ensembles
Víctor Blanco, Alberto Japón, Justo Puerto +1
In this paper we provide a novel mathematical optimization based methodology to perturb the features of a given observation to be re-classified, by a tree ensemble classification r…
A Mathematical Programming Approach to Optimal Classification Forests
Víctor Blanco, Alberto Japón, Justo Puerto +1
This paper introduces Weighted Optimal Classification Forests (WOCFs), a new family of classifiers that takes advantage of an optimal ensemble of decision trees to derive accurate…
Multiclass Optimal Classification Trees with SVM-splits
Víctor Blanco, Alberto Japón, Justo Puerto
In this paper we present a novel mathematical optimization-based methodology to construct tree-shaped classification rules for multiclass instances. Our approach consists of buildi…
On the multisource hyperplanes location problem to fitting set of points
Víctor Blanco, Alberto Japón, Diego Ponce +1
In this paper we study the problem of locating a given number of hyperplanes minimizing an objective function of the closest distances from a set of points. We propose a general fr…
Optimal arrangements of hyperplanes for multiclass classification
Víctor Blanco, Alberto Japón, Justo Puerto
In this paper, we present a novel approach to construct multiclass classifiers by means of arrangements of hyperplanes. We propose different mixed integer (linear and non linear) p…
