Bootstrapping Dirac ensembles

چکیده
We apply the bootstrap technique to find moments of certain multi-trace and multi-matrix random matrix models suggested by noncommutative geometry. Using bootstrapping we are able relationships between coupling constant these their second moments. Schwinger-Dyson equations, all other can be expressed in terms moment. Explicit relations for higher mixed obtained.

Penta-Training: Clustering Ensembles with Bootstrapping of Constraints
In this paper we combine clustering ensembles and semisupervised clustering to address the ill-posed nature of clustering. We introduce a mechanism which leverages the ensemble framework to bootstrap informative constraints directly from the data and from the various clusterings, without intervention from the user. Our approach is well suited for problems where the information available from an...
متن کاملA Novel Bootstrapping Method for Positive Datasets in Cascades of Boosted Ensembles
We present a novel method for efficiently training a face detector using large positive datasets in a cascade of boosted ensembles. We extend the successful Viola-Jones [1] framework which achieved low false acceptance rates through bootstrapping negative samples with the capability to also bootstrap large positive datasets thereby capturing more in-class variation of the target object. We achi...
متن کاملClass-Separability Weighting and Bootstrapping in Error Correcting Output Code Ensembles
A method for applying weighted decoding to error-correcting output code ensembles of binary classifiers is presented. This method is sensitive to the target class in that a separate weight is computed for each base classifier and target class combination. Experiments on 11 UCI datasets show that the method tends to improve classification accuracy when using neural network or support vector mach...
متن کاملExact recovery of Dirac ensembles from the projection onto spaces of spherical harmonics
In this work we consider the problem of recovering an ensemble of Diracs on the sphere from its projection onto spaces of spherical harmonics. We show that under an appropriate separation condition on the unknown locations of the Diracs, the ensemble can be recovered through Total Variation norm minimization. The proof of the uniqueness of the solution uses the method of ‘dual’ interpolating po...
متن کاملOn the Microscopic Spectra of the Massive Dirac Operator for Chiral Orthogonal and Chiral Symplectic Ensembles
Using Random Matrix Theory we set out to compute the microscopic correlators of the Euclidean Dirac operator in four dimensions. In particular we consider: the chiral Orthogonal Ensemble (χOE), corresponding to a Yang-Mills theory with two colors and fermions in the fundamental representation, and the chiral Symplectic Ensemble (χSE), corresponding to any number of colors and fermions in the ad...
