Reinforcement learning typically assumes that agents observe feedback for their actions immediately, but in many real-world applications (like recommendation systems) is observed delay. This paper studies online episodic Markov decision processes (MDPs) with unknown transitions, adversarially changing costs and unrestricted delayed feedback. That is, the trajectory of episode k are revealed to ...

In this paper, we propose a delayed multiple copy retransmission (D-MCR) scheme. By using Markovian analytic method we present the performance evaluation of the D-MCR scheme in correlated fading channels. Both effective throughput and number of retransmissions are derived. The analytic results show that the D-MCR scheme can improve the performance greatly, especially in slow fading channels.

بخش اورژانس یکی از شلوغ‌ترین بخش‌های یک بیمارستان است و بهبود عملکرد این تأثیر بسیاری در کیفیت ارائه خدمات دارد. اخیراً پژوهشگران به­‌دلیل تمرکز مهندسی تاب‌آوری مدیریت ناب بر کارایی سیستم‌ها توجه بسیار زیادی به دو دیدگاه کنار یکدیگر داشته‌اند. هدف پژوهش، رویکردی یکپارچه برای ارزیابی مبتنی شاخص‌های با ارتقای رضایت شغلی کاهش هزینه‌های درمانی واحد خصوصی است. منظور، ابتدا شناسایی مؤثر، مدل مفهومی مس...

The adjuvant activity of 29 kinds of carbohydrate analogs of N-acetylmuramyl-L-alanyl-D-isoglutamine on the induction of delayed-type hypersensitivity to azobenzenearsonate-N-acetyl-L-tyrosine was examined in guinea pigs. It was found that the D-manno- and D-galacto-type muramyldipeptides were as active as the D-gluco-type muramyldipeptide (MDP). The structural requirement of the carbohydrate m...

This study aims to investigate the effect of early and delayed injury minimally invasive percutaneous plate osteosynthesis on the treatment of distal tibial metaphyseal comminuted fracture. This study involved 90 patients with distal tibial metaphyseal comminuted fractures for treatment of minimally invasive percutaneous plate osteosynthesis between February 2012 and October 2014 in our hospita...

purpose : patients with infantile or childhood strabismus who do not achieve visual axes alignment early in life are believed to have poor prognosis with respect to the stereopsis. this study investigates the binocularity and stereopsis following delayed surgical alignment in patients with congenital and early-onset strabismus. patients & methods : 36 patients aged between 6-30 years participat...

conclusions: in this study, delay in diagnosis was similar to other studies. educating physicians to careful history taking especially in the case of ibp, non-musculoskeletal symptoms such as uveitis and precise physical examination are important in early diagnosis. patients and methods: sixty patients, (53 males, 7 females) with a diagnosis of as according to the modified new york criteria wer...
