We propose a novel multi-party computation protocol for evaluating continuous real-valued functions with high numerical precision. Our method is based on approximations with Fourier series and uses at most two rounds of communication during the online phase. For the offline phase, we propose a trusted-dealer and honest-but-curious aided solution, respectively. We apply our algorithm to train a ...

The sparse estimation methods that utilize the ℓp-norm, with p being between 0 and 1, have shown better utility in providing optimal solutions to the inverse problem in diffuse optical tomography. These ℓp-norm-based regularizations make the optimization function nonconvex, and algorithms that implement ℓp-norm minimization utilize approximations to the original ℓp-norm function. In this work, ...

Kernel Logistic Regression (KLR) is one of the statistical models that have been proposed for classification in the machine learning and data mining communities, and also one of the effective methodologies in the kernel-machine techniques. The parameters of KLR model are usually fitted by the solution of a convex optimization problem that can be found using the well known Iteratively Reweighted...

Compressive Sampling (CS) is a new method of signal acquisition and reconstruction from frequency data which do not follow the basic principle of the Nyquist-Shannon sampling theory. This new method allows reconstruction of the signal from substantially fewer measurements than those required by conventional sampling methods. We present and discuss a new, swarm based, technique for representing ...

According to clinical guidelines, dopamine agonists are the first-line treatment of restless legs syndrome (RLS). To evaluate efficacy and safety of dopamine agonists for RLS. We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 4), MEDLINE, EMBASE, PsycINFO and CINAHL, from January 1985 to December 2008, plus reference lists of articles. We contacted...

Restless leg syndrome is a nervous system disorder that causes an overpowering urge to move one’s legs. Symptoms of restless usually worsen when one tries fall asleep and can prevent sufficient sleep. common in patients with chronic kidney failure be caused or worsened by hemodialysis. Various medications treat syndrome, though the long-term use cause augmentation adverse effects. In addition, ...

<span lang="EN-US">Electrical impedance tomography (EIT), as a non-ionizing method, has been widely used in various fields of application, such engineering and medical fields. This study applies an iterative process to reconstruct EIT images using the simultaneous algebraic reconstruction technique (SART) algorithm combined with K-means clustering. The started defining finite element meth...

This dissertation presents data processing techniques relevant to the acquisition, modeling, and inversion of self-potential data. The primary goal is to facilitate the interpretation of self-potentials in terms of the underlying mechanisms that generate the measured signal. The central component of this work describes a methodology for inverting self-potential data to recover the three-dimensi...
