Averaged Probabilistic Relational Models
Most real-world data is stored in relational form. In contrast, most statistical learning methods work with “flat” data representations, forcing us to convert our data into a form that loses much of the relational structure. The recently introduced framework of Probabilistic Relational Models (PRMs) allows us to represent probabilistic models over multiple entities that utilize the relations be...
متن کاملCycle-averaged dynamics of a periodically driven, closed-loop circulation model.
Time-varying elastance models have been used extensively in the past to simulate the pulsatile nature of cardiovascular waveforms. Frequently, however, one is interested in dynamics that occur over longer time scales, in which case a detailed simulation of each cardiac contraction becomes computationally burdensome. In this paper, we apply circuit-averaging techniques to a periodically driven, ...
متن کاملVariational principles for Lagrangian-averaged fluid dynamics
Abstract The Lagrangian average (LA) of the ideal fluid equations preserves their fundamental transport structure. This transport structure is responsible for the Kelvin circulation theorem of the LA flow and, hence, for its potential vorticity convection and helicity conservation. We show that Lagrangian averaging also preserves the Euler–Poincaré variational framework that implies the exact i...
متن کاملAveraged Configurations from Molecular Dynamics Simulations
One of the challenges in the large scale simulations required for biomolecular system is the recording, monitoring and visualization of configurational information from molecular dynamics trajectories. A detailed record of instantaneous configuration along the full trajectory can quickly become unmanageable. In this paper we will describe an alternative approach where configurations averaged ov...
متن کاملSpace-modulated Stability and Averaged Dynamics
In this brief note we give a brief overview of the comprehensive theory, recently obtained by the author jointly with Johnson, Noble and Zumbrun, that describes the nonlinear dynamics about spectrally stable periodic waves of parabolic systems and announce parallel results for the linearized dynamics near cnoidal waves of the Korteweg–de Vries equation. The latter are expected to contribute to ...
