This paper presents a novel fusion method for final decision making in multiple classifier system. The novel approach proposed fuses multiple individual classifiers through normalizing and re-subdividing classification output space. Firstly, each class decision output of each classifier in multiple classifier system is divided into four spaces by reliability of corresponding classifier. And then, reject degree is used to indicate classification to substitute for original output. Secondly, dynamic probability of each reject degree which used to combine multiple classifiers is calculated by using synchronization decision support value defined in this paper. Finally, the final decision can be made by integrated support degree based on support space of all classes. Experimental results demonstrate that the method is able to achieve a preferable solution, which has a better classification performance compared to single classifier and other combination methods.

Traditionally, a single sensor is always used to provide several machine components operating condition for fault diagnosis. Fault diagnosis based on this approach is difficult to obtain satisfactory results, especially in the severe operating environment. This paper proposes a new feature-level fusion model based on gene expression programming. And the new fusion model fuses machine component operating features from more than one sensor in parallel. Firstly, calculate time-domain feature parameters of each sensor signal. Secondly, construct multi-sensor feature-level fusion model by using gene expression programming. Finally, identify the integration information and make decisions for machine components fault diagnosis. Experiments show that the new approach can achieve better performance than single sensor approach, and it is able to further improve the accuracy of fault diagnosis. © 2010 Binary Information Press.

This work presents a new inclusive search for supersymmetry (SUSY) by the ATLAS experiment at the LHC in proton-proton collisions at a center-of-mass energy s=7 TeV in final states with jets, missing transverse momentum and one or more isolated electrons and/or muons. The search is based on data from the full 2011 data-taking period, corresponding to an integrated luminosity of 4.7 fb−1. Single-lepton and multilepton channels are treated together in one analysis. An increase in sensitivity is obtained by simultaneously fitting the number of events in statistically independent signal regions, and the shapes of distributions within those regions. A dedicated signal region is introduced to be sensitive to decay cascades of SUSY particles with small mass differences (“compressed SUSY”). Background uncertainties are constrained by fitting to the jet-multiplicity distribution in background control regions. Observations are consistent with Standard Model expectations, and limits are set or extended on a number of SUSY models.

In order to improve the reliability of fault detection and diagnosis for dynamic system, it is important to make full use of the information from different component of system. Multiple classifiers fusion is a technique that combines the decisions of different classifiers as to reduce the variance of estimation errors and improve the overall classification accuracy. This paper proposes a novel multiple classifiers fusion using within-class decision support for fault diagnosis. The new approach considers the fault diagnosis problem in time series. Then, one-step time series within-class decision support value and synchronization withinclass decision support value are calculated to get association probability of each classifier in the same class recognition. Finally, calculate the fusion posterior probability outputs and normalize them for final decision. Experimental results demonstrate that the method is able to achieve a preferable solution, which has a better classification performance compared to single classifier.

Patch-based reconstruction and rendering of human heads

Patch-based reconstruction and rendering of human heads

IEEE International Conference on Image Processing

作者： David C. Schneider Anna Hilsmann Peter Eisert Computer Vision and Graphics Group Fraunhofer Heinrich Hertz Institute (HHI) Berlin Germany Department of Computer Science Humboldt-Universität zu Berlin Berlin Germany

Reconstructing the 3D shape of human faces is an intensively researched topic. Most approaches aim at generating a closed surface representation of geometry, i.e. a mesh, which is texture-mapped for rendering. However, if free viewpoint rendering is the primary purpose of the reconstruction, representations other than meshes are possible. In this paper a coarse patch-based approach to both reconstruction and rendering is explored and applied not only to the face but the whole human head. The approach has advantages on parts of the scene that are traditionally difficult to reconstruct and render, which is the case for hair when it comes to human heads. In the paper, reconstruction of a patch is posed as a parameter estimation problem which is solved in a generic image-based optimization framework using the Levenberg-Marquard algorithm. In order to improve robustness, the Huber error metric is used and a geometric regularization strategy is introduced. Initial values for the optimization, which are crucial for the method's success, are obtained by triangulation of SIFT feature points and a recursive expansion scheme.

In this paper we propose a synthesis semantics for SystemC™ channels, which contribute to a clear separation between computation (algorithm) and communication, whereas communication related parts are modelled through either primitive or hierarchical channels. We present a synthesisable replacement for SystemC primitive channels that allows deterministic access scheduling and user-constrained refinement for HW/HW and HW/SW communication. We demonstrate the feasibility of our approach through synthesis and exploration of a communication intensive packet switch design under consideration of different configurations and communication refinements.

A measurement of the cross section for the production of an isolated photon in association with jets in proton-proton collisions at a center-of-mass energy s=7 TeV is presented. Photons are reconstructed in the pseudorapidity range |ηγ|<1.37 and with a transverse energy ETγ>25 GeV. Jets are reconstructed in the rapidity range |yjet|<4.4 and with a transverse momentum pTjet>20 GeV. The differential cross section dσ/dETγ is measured, as a function of the photon transverse energy, for three different rapidity ranges of the leading-pT jet: |yjet|<1.2, 1.2≤|yjet|<2.8 and 2.8≤|yjet|<4.4. For each rapidity configuration the same-sign (ηγyjet≥0) and opposite-sign (ηγyjet<0) cases are studied separately. The results are based on an integrated luminosity of 37 pb−1, collected with the ATLAS detector at the LHC. Next-to-leading order perturbative QCD calculations are found to be in fair agreement with the data, except for ETγ≲45 GeV, where the theoretical predictions overestimate the measured cross sections.

We consider a generalization of Voronoi diagrams, recently introduced by Barequet et al., in which the distance is measured from a pair of sites to a point. An easy way to define such distance was proposed together with the concept: it can be the sum-of, the product-of, or (the absolute value of) the difference-between Euclidean distances from either site to the respective point. We explore further the last definition, and analyze the complexity of the nearest- and the furthest- neighbor 2-site Voronoi diagrams for points in the plane with Manhattan or Chebyshev underlying metrics, providing extensions to general Minkowsky metrics and, for the nearest- neighbor case, to higher dimensions. In addition, we point out that the observation made earlier in the literature that 2-point site Voronoi diagrams under the sum-of and the product-of Euclidean distances are identical and almost identical to the second order Voronoi diagrams, respectively, holds in a much more general statement. © 2010 IEEE.

It was shown in the past that ATPG based on the Boolean Satisfiability problem is a beneficial complement to traditional ATPG techniques. Its advantages can be observed especially on large industrial circuits. These circuits usually contain a lot of functional redundancy which, on the one hand, is often needed during operational mode, but on the other hand, causes dispensable overhead during ATPG. Using the traditional circuit-to-CNF transformation, this redundancy is also contained in the SAT instances. The contribution of this paper is a new technique to improve the SAT instance generation for SAT-based ATPG. The objective of the proposed method is to use Binary Decision Diagrams (BDDs) to optimize the resulting CNF representations. In order to apply the proposed technique to industrial circuits, we developed dedicated BDD operations using a multiple-valued logic. The experimental results, obtained on large industrial designs, show that the accomplished optimizations result in a considerable acceleration of the overall ATPG runtime as well as in a significant reduction of the unclassified faults.
