We propose zoneout, a novel method for regularizing RNNs. At each timestep, zoneout stochastically forces some hidden units to maintain their previous values. Like dropout, uses random noise train pseudo-ensemble, improving generalization. But by preserving instead of dropping units, gradient information and state are more readily propagated through time, as in feedforward stochastic depth networks. perform an empirical investigation various RNN regularizers, find that gives significant...

We identify and formalize a fundamental gradient descent phenomenon resulting in learning proclivity over-parameterized neural networks. Gradient Starvation arises when cross-entropy loss is minimized by capturing only subset of features relevant for the task, despite presence other predictive that fail to be discovered. This work provides theoretical explanation emergence such feature imbalance Using tools from Dynamical Systems theory, we simple properties dynamics during lead this...

Aim. To evaluate the diagnostic value of ultrasonography and magnetic resonance imaging (MRI) in patients with ulnar neuropathy at elbow (UNE). Methods. We prospectively performed electrodiagnostic, ultrasonographic, MRI studies UNE healthy controls. Three cross-sectional area (CSA) measurements nerve multiple levels along arm maximum CSA(-max) were recorded. Results. The CSA different between severity grades (P < 0.05). CSA-max had greatest sensitivity (93%) specificity (68%). Moreover, ≥10...

Introduction: Numerous factors contribute to the advancement of progressive kidney damage in chronic disease (CKD). Among these, oxidative plays a significant role progression CKD. The reactions involving free radicals are recognized as crucial element that can exacerbate patients with However, precise mechanisms underlying remain incompletely understood. Consequently, this study aimed explore and other associated biochemical parameters. Materials Methods: This case-control included 38 male...

Adverse reactions induced by BCG vaccination are rare, disseminated mycobacterial infection in particular, which is often fatal and results from impaired immunity. The aim of this study to determine the nature immunodeficiences patients with northwest region Iran. Through 2 years all infants adenitis or other complications vaccine that had suspicious were referred children's hospital health centers Tabriz. Evaluation immune system some cases genetic survey was performed evidence...

Background: magnetic resonance imaging (MRI) as a noninvasive diagnostic tool may help clinicians in the evaluation of injuries to menisci and ligaments.Purpose: this study assessed associations between type trauma knee joint, bone bruise, fracture pathological joint effusion with ligaments joint.Methods: we reviewed MRI 175 patients aged less than 45 years old who were referred center our University.Results: statistical analysis showed that tearing medial meniscus (MM) is significantly more...

Background: Following the implementation of family physician program in 2004 Iranian healthcare system, understanding changes physicians' practice has become important. Objective: The objective this study was to determine level job satisfaction and its relationship with their performance level. Materials Methods: A cross-sectional conducted among all 367 physicians East Azerbaijan province during December 2009 May 2011 using a self-administered, anonymous questionnaire for satisfaction....

Purpose: To perform an inclusive search for original studies that report medical overuse in the Iranian healthcare system and discovering area of overuse. Patients Methods: A systematic literature is conducted bibliographic databases including PubMed, Embase, Scopus, Web Sciences, Cochrane Scientific Information Database using a comprehensive strategy without time limit until end 2018, updated by 1 July 2020, accomplished reference tracking, author contacting expert consultation to identify...

This study was done to evaluate the validity and reliability of women's reproductive history questionnaire which will be used in Azar Cohort study; a cohort that is conducted by Tabriz University Medical Science Shabestar county for identifying risk factors no communicable diseases.Content face were evaluated ten experts field quantified as content index (CVI) ratio (CVR).To assess reliability, using test-retest approach, kappa statistic calculated categorical variables intra-class...

Summary The availability of safe and effective factor replacement therapies, in persons with haemophilia ( PWH ), has some countries answered the basic need for treatment these patients. findings suggest that adult patients who have always been on prophylaxis reported significantly better physical functioning, thus quality life. This study is designed to evaluate QoL , by focusing social determinants their relationship health‐related dimensions, Tabriz, Iran. survey instrument was a...

Millions of children who were born during the first decade after Islamic revolution in Iran are now reaching age marriage and childbearing. Short spacing between birth child has potential to cause an excessive costly increase growth population Iran. Research into motivations for among newly married couples can create a knowledge base that will enable health centres help these make better decisions about timing their pregnancy. Using consecutive sampling technique administering Miller’s...

BACKGROUND: Overuse and underuse of healthcare services occure within population, organizations even patients around the world. Producing a balance between these two can increase efficiency, service quality patient satisfaction. It also decrease extra costs. The aim this study was to identify forces for change against generating overuse achieve right care.METHODS: This conducted in five steps: 1) describe our plan or proposal change; 2) 3) 4) assign forces; 5) analyze apply. We used...

Background: Considering the importance of assessing program health promotion hospitals (HPH) for elucidating compliance with standards, present study aimed to evaluate standards in governmental and nongovernmental East-Azerbaijan. Methods: In cross-sectional study, all East-Azerbaijan province 2018 were recruited. The Persian validated World Health Organization (WHO) a self-assessment questionnaire was sent director each hospital invited corporate study. Self-assessment consists 40...

While a lot of progress has been made in recent years, the dynamics learning deep nonlinear neural networks remain to this day largely misunderstood. In work, we study case binary classification and prove various properties such under strong assumptions as linear separability data. Extending existing results from case, confirm empirical observations by proving that error also follows sigmoidal shape architectures. We show given proper initialization, expounds parallel independent modes...
