Estimating functions for diffusion-type processes

by Michael Sørensen
"... In this chapter we consider parametric inference based on discrete time observations X0, Xt1,...,Xtn from a d-dimensional stochastic process. In most of the chapter the statistical model for the data will be a diffusion model given by a stochastic differential equation. We shall, however, also consi ..."

MARKOV DILATION OF DIFFUSION TYPE PROCESSES AND ITS APPLICATION TO THE FINANCIAL

by R. Tevzadze
"... Abstract. The Markov dilation of diffusion type processes is defined. Infinitesimal operators and stochastic differential equations for the obtained Markov processes are described. Some applications to the integral representation for functionals of diffusion type processes and to the construction of ..."

MODERATE DEVIATIONS FOR A DIFFUSION TYPE PROCESS IN RANDOM ENVIRONMENT

by P. Chigansky, R. Liptser , 2007
"... Abstract. Let σ(u), u ∈ R be an ergodic stationary Markov chain, taking a finite number of values a1,..., am, and b(u) = g(σ(u)), where g is a bounded and measurable function. We consider the diffusion type process dX ε t = b(X ε t /ε)dt + ε κ σ ` X ε t /ε ´ dBt, t ≤ T subject to X ε 0 = x0, where ..."

Implicit Fairing of Irregular Meshes using Diffusion and Curvature Flow

by Mathieu Desbrun , Mark Meyer, Peter Schröder, Alan H. Barr , 1999
"... In this paper, we develop methods to rapidly remove rough features from irregularly triangulated data intended to portray a smooth surface. The main task is to remove undesirable noise and uneven edges while retaining desirable geometric features. The problem arises mainly when creating high-fidelit ..."

-fidelity computer graphics objects using imperfectly-measured data from the real world. Our approach contains three novel features: an implicit integration method to achieve efficiency, stability, and large time-steps; a scale-dependent Laplacian operator to improve the diffusion process; and finally, a robust

Directed Diffusion for Wireless Sensor Networking

by Chalermek Intanagonwiwat, Ramesh Govindan, Deborah Estrin, John Heidemann, Fabio Silva - IEEE/ACM Transactions on Networking , 2003
"... Advances in processor, memory and radio technology will enable small and cheap nodes capable of sensing, communication and computation. Networks of such nodes can coordinate to perform distributed sensing of environmental phenomena. In this paper, we explore the directed diffusion paradigm for such ..."

for such coordination. Directed diffusion is datacentric in that all communication is for named data. All nodes in a directed diffusion-based network are application-aware. This enables diffusion to achieve energy savings by selecting empirically good paths and by caching and processing data in-network (e.g., data

Transform Analysis and Asset Pricing for Affine Jump-Diffusions

by Darrell Duffie, Jun Pan, Kenneth Singleton - Econometrica , 2000
"... In the setting of ‘‘affine’ ’ jump-diffusion state processes, this paper provides an analytical treatment of a class of transforms, including various Laplace and Fourier transforms as special cases, that allow an analytical treatment of a range of valuation and econometric problems. Example applicat ..."

Scale-space and edge detection using anisotropic diffusion

by Pietro Perona, Jitendra Malik - IEEE Transactions on Pattern Analysis and Machine Intelligence , 1990
"... Abstract-The scale-space technique introduced by Witkin involves generating coarser resolution images by convolving the original image with a Gaussian kernel. This approach has a major drawback: it is difficult to obtain accurately the locations of the “semantically mean-ingful ” edges at coarse sca ..."

The diffusion coefficient is chosen to vary spatially in such a way as to encourage intraregion smoothing in preference to interregion smoothing. It is shown

The Valuation of Options for Alternative Stochastic Processes
