Stochastic variational inequalities (SVI) model a large class of equilibrium problems subject to data uncertainty, and are closely related to stochastic optimization problems. The SVI solution is usually estimated by a solution to a sample average approximation (SAA) problem. This paper considers the normal map formulation of an SVI, and proposes a method to build asymptotically exact confidenc...
Stochastic variational inference (SVI) maps posterior inference in latent variable models to nonconvex stochastic optimization. While they enable approximate posterior inference for many otherwise intractable models, variational inference methods suffer from local optima. We introduce deterministic annealing for SVI to overcome this issue. We introduce a temperature parameter that deterministic...
The aim of the present study was to test the validity of the transthoracic electrical bioimpedance method PhysioFlow® to measure stroke volume in patients with chronic anemia. Stroke volume index (SVI), as well as cardiac index (CI) obtained by transthoracic electrical bioimpedance method and doppler echocardiography were compared in healthy subjects (n = 25) and patients with chronic anemia (i...
While left ventricular (LV) performance in patients with coronary artery disease (CAD) has been extensively investigated, little attention has been given to right ventricular (RV) function in this disease. For this purpose, a new geometric model for RV volume has been developed and RV end-diastolic volume index (EDVI), end-systolic volume index (ESVI), stroke volume index (SVI) and ejection fra...
OBJECTIVE To externally validate the updated 2012 Partin Tables in contemporary North American patients treated with radical prostatectomy (RP) for localized prostate cancer (PCa) at community institutions. MATERIALS AND METHODS We examined records of 25,254 patients treated with RP and pelvic lymph node dissection (PLND) between 2010 and 2013, within the surveillance, epidemiology, and end r...
Objective. Though prehypertension has strong familial predisposition, difference in pathophysiological mechanisms in its genesis in offspring of both parents and single parent hypertensive have not been elucidated. Methods. Body mass index (BMI), waist-hip ratio (WHR), basal heart rate (BHR), blood pressure (BP), HR and BP response to standing, deep breathing difference, BP response to handgrip...
To achieve the 4X time-to-market and life cycle cost improvement goals of the RASSP program, designers must focus not only on how they design, but on what they design as well. Lockheed Martin’s Advanced Technology Labs is developing a Model Year Architecture (MYA) that promotes design upgrades and reuse via standardized, open interfaces while leveraging state-of-theart commercial technology dev...
Owing to the recent advances in “Big Data” modeling and prediction tasks, variational Bayesian estimation has gained popularity due to their ability to provide exact solutions to approximate posteriors. One key technique for approximate inference is stochastic variational inference (SVI) [1]. SVI poses variational inference as a stochastic optimization problem and solves it iteratively using no...
