Hierarchical Holographic Modeling
IEEE Transactions on Systems, Man, and Cybernetics, 1981A first-phase development of a mathematical theory for a new modeling schema that is termed hierarchical holographic modeling is presented. This theory will provide a methodology for capturing and dealing with a fundamental, but heretofore neglected, characteristic of large-scale systems-their multifarious nature.

Computerized Medical Imaging and Graphics, 1997
In this paper, a hierarchical model for Picture Archiving and Communication Systems (HPACS) is presented and implemented at Taichung Veterans General Hospital (TCVGH) in Taiwan. Despite the fact that the HPACS is built on the architecture of the second generation PACS, it offers many improved features and has advantages over the second generation PACS,

Hierarchical hypersurface modeling
1994We propose a new model for representing a hypersurface describing a scalar field in any dimension at different levels of detail. The model is based on a decomposition of the domain into a hierarchy of simplicial complexes. We present a data structure for encoding such model as well as an algorithm for building a multiresolution representation of a ...

Publisher Summary This chapter describes the Bayesian hierarchical models. The evaluation of this study, by a Bayesian hierarchical linear model is derived from the data that include the other large clinical trials of thrombolytic therapy and suggests that treatment is also beneficial for patients, arriving much later than six hours after symptom ...

Evaluation Methods of Hierarchical Models
2018In this paper, we consider the problem of evaluating the quality of hierarchical models. This task arises due to the current researchers use subjective evaluation, such as a survey to test the goodness of a hierarchy discovered by their models. We propose three methods to evaluate the quality of hierarchy extracted from unstructured text. These methods

Hierarchical model predictive control
2007 46th IEEE Conference on Decision and Control, 2007This paper deals with the problem of designing stable hierarchical control schemes with Model Predictive Control (MPC). Specifically, at any layer of the considered structure, a robust MPC regulator is used to compute the control variables. In turn, these variables are produced by the subsystems at lower layers and must fulfill the robustness ...

On Invariance in Hierarchical Models.
2009A goal of central importance in the study of hierarchical models for object recognition -- and indeed the visual cortex -- is that of understanding quantitatively the trade-off between invariance and selectivity, and how invariance and discrimination properties contribute towards providing an improved representation useful for learning from data.
