Graphical Models as Surrogates for Complex Ground Motion Models
نویسندگان
چکیده
1. Ground Motion Models • describe ground motion caused by earthquakes given event and site related predictor variables • a popular model, based on physical principles, is the so-called stochastic model a • because of its complexity, a surrogate model is often used instead • usually a regression function is fitted through data generated by the stochastic model; the functional form is derived from expert knowledge; e.g.:

A study on the accuracy of motion tracking of thoracic tumors at radiotherapy with external surrogates
Introduction: In radiotherapy with external surrogates, exact information of tumor position is one of the key factors that improves treatment delivery. Many dynamic tumors in thorax region of patient move mainly due to respiration and are known as intra-fractional motion error that must be compensated, as well. One of clinical strategy is using Stereotactic Body Radiation Thera...
متن کاملGraphical Models for Surrogates
Recently, it has been demonstrated that graphical models promise some potential for expressing causal concepts, see for example Pearl (2000), Lauritzen (2001), or Dawid (2002). The causal interpretation is most direct in models based on directed acyclic graphs, whereas causal interpretation for chain graph models generally is more subtle and complex (Lauritzen and Richardson 2002). In the artic...
متن کاملA quantitative investigation on lung tumor site on its motion tracking in radiotherapy with external surrogates
Introduction: In external beam radiotherapy each effort is done to deliver 3D dose distribution onto the tumor volume uniformly, while minimizing the dose to healthy organs at the same time. Radiation treatment of tumors located at thorax region such as lung and liver has a challenging issue during target localization since these tumors move mainly due to respiration. There are...
متن کاملVertical Dynamics Modeling and Simulation of a Six-Wheel Unmanned Ground Vehicle
Vertical dynamics modeling and simulation of a six-wheel unmanned military vehicle (MULE) studied in this paper. The Common Mobility Platform (CMP) chassis provided mobility, built around an advanced propulsion and articulated suspension system gave the vehicle ability to negotiate complex terrain, obstacles, and gaps that a dismounted squad would encounter. Aiming at modeling of vehicle vertic...
متن کاملSparse and Locally Constant Gaussian Graphical Models
Locality information is crucial in datasets where each variable corresponds to a measurement in a manifold (silhouettes, motion trajectories, 2D and 3D images). Although these datasets are typically under-sampled and high-dimensional, they often need to be represented with low-complexity statistical models, which are comprised of only the important probabilistic dependencies in the datasets. Mo...
