Multimethod machine learning approach for medical diagnosing
(IEEE, 2003-04)
In this paper we present a multimethod approach for induction of a specific class of classifiers, which can assist physicians in medical diagnosing in the case of mitral valve prolapse. Mitral valve prolapse is one of the ...
Number of arrhythmia beats determination in Holter electrocardiogram: How many clusters?
(IEEE, 2003-09)
Holter signals correspond to long-term electrocardiograph (ECG) registers. Manual inspection of such signals is difficult because of the enormous quantity of beats involved. Throughout the literature several methods of ...
A Linear Programming Approach to Max-sum Problem: A Review
(Center for Machine Perception, Department of Cybernetics, Faculty of Electrical Engineering, Czech Technical University, 2005-12)
The max-sum labeling problem, de ned as maximizing a sum of functions of pairs of discrete variables, is a general optimization problem with numerous applications, e.g., computing MAP assignments of a Markov random eld. ...
Joint Orientation of Epipoles
(British Machine Vision Association, 2003-09)
It is known that epipolar constraint can be augmented with orientation by formulating it in the oriented projective geometry. This oriented epipolar constraint requires knowing the orientations (signs of overall scales) ...
Model Selection for Automated Architectural Reconstruction from Multiple Views
(British Machine Vision Conference (BMVC), 2002-09)
We describe progress in automatically fitting a plane plus modelled perturbation surface model to represent architectural scenes. There are two areas of novelty. The first is a method of fitting parametrized models in which ...
Unified Framework for Semiring-Based Arc Consistency and Relaxation Labeling
(Verlag der Technischen Universität Graz, 2007-02)
Constraint Satisfaction Problem (CSP), including its soft modifications, is ubiquitous in artificial intelligence and related fields. In computer vision and pattern recognition, the crisp CSP is more known as the consistent ...
What Is Decreased by the Max-sum Arc Consistency Algorithm?
(ACM, 2007)
Inference tasks in Markov random fields (MRFs) are closely related to the constraint satisfaction problem (CSP) and its soft generalizations. In particular, MAP inference in MRF is equivalent to the weighted (maxsum) CSP. ...
Revisiting the Linear Programming Relaxation Approach to Gibbs Energy Minimization and Weighted Constraint Satisfaction
(IEEE, 2010)
We present a number of contributions to the LP relaxation approach to weighted constraint satisfaction (= Gibbs energy minimization). We link this approach to many works from constraint programming, which relation has so ...
Revisiting the Decomposition Approach to Inference in Exponential Families and Graphical Models
(Center for Machine Perception, Department of Cybernetics, Faculty of Electrical Engineering, Czech Technical University, 2009-05)
Fixed Points of Loopy Belief Propagation as Zero Gradients of a Function of Reparameterizations
(Center for Machine Perception, Department of Cybernetics, Faculty of Electrical Engineering, Czech Technical University, 2010-02)
The existing view on loopy belief propagation sees it as an algorithm to nd a common zero of a system of non-linear functions, not explicitly related to each other. We show that these functions are in fact related { they ...
