Sequential Gaussian Mixture Models for Two-Level Conditional Random Fields

Conditional Random Fields are among the most popular techniques for image labelling because of their flexibility in modelling dependencies between the labels and the image features. This paper addresses the problem of efficient classification of partially occluded objects. For this purpose we propose a novel Gaussian Mixture Model based on a sequential training procedure, in combination with mu...

Scaling Laws for Microemulsions Governed by Spontaneous Curvature

We introduce a model for microemulsions whose basic building blocks are cylindrical tubes connected by spherical junctions forming a network. The model predicts analytic scaling laws which quantitatively reproduce several prominent experimental features of the phase diagram, including the closed loops of 2-phase coexistence and the 3-phase body. The interfacial nature of our model, which takes ...

Credit Risk Modeling with Gaussian Random Fields

The literature on credit risk consists of different approaches in modeling the behavior of defaultable bonds. The structural approach is based on the evolution of the firm value to determine default and recovery. In contrast, the more recently developed intensity-based models specify the default time exogenously. In this approach the defaultable yield curve results from the risk-free yield curv...

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
