Adapting the Stochastic Block Model to Edge-Weighted Networks
Adapting Stochastic Block Model Edge-Weighted Networks
2013/6/14
We generalize the stochastic block model to the important case in which edges are annotated with weights drawn from an exponential family distribution. This generalization introduces several technical...
Interval edge estimation in SAR images
Bootstrap confidence interval maximum likelihood synthetic aperture radar SAR
2013/4/27
This paper considers edge interval estimation between two regions of a Synthetic Aperture Image which differ in texture. Different point estimation strategies under multiplicative noise are discussed ...
A spatio-spectral hybridization for edge preservation and noisy image restoration via local parametric mixtures and Lagrangian relaxation
Edge preserving smoother Semiparametric mixture model Partition of unity MISE Variational optimization Thin Plate Splines Spectral embedding Local template mod-els Multiple hypothesis testing.
2012/11/22
This paper investigates a fully unsupervised statistical method for edge preserving image restoration and compression using a spatial decomposition scheme. Smoothed maximum likelihood is used for loca...
Generating Markov Equivalent Maximal Ancestral Graphs by Single Edge Replacement
Markov Equivalent Maximal Ancestral Single Edge Replacement
2012/9/19
Maximal ancestral graphs(MAGs) are used to encode conditional independence relations in DAG models with hidden variables. Di erent MAGs may represent the same set of con-ditional independences and are...
Nonparametric Edge Detection in Speckled Imagery
Edge detection hypothesis testing image analysis multiplicative noise small samples speckle SAR
2012/9/19
We address the issue of edge detection in Synthetic Aperture Radar imagery. In particular, we propose nonparametric methods for edge detection, and numeri-cally compare them to an alternative method t...
Soft edge results for longest increasing paths on the planar lattice
Soft edge results longest increasing paths the planar lattice
2010/2/24
For two-dimensional last-passage time models of weakly increasing paths, interesting scaling limits have been proved for points close the axis (the hard edge). For strictly increasing paths of Bernoul...
Sharp edge，vertex，and mixed Cheeger type inequalities for finite Markov kernels
Sharp edge vertex mixed Cheeger type finite Markov kernels
2009/3/31
We show how the evolving set methodology of Morris and Peres can be used to show Cheeger inequalities for bounding the spectral gap of a finite Markov kernel. This leads to sharp versions of several p...
