The article deals with the problem of recognition handwritten digits using feedforward neural networks (perceptrons) a correlation indicator. proposed method is based on mathematical model network as an oscillatory system similar to information transmission system. uses theoretical developments authors search for global extremum error function in artificial networks. digit image considered one-...
Concerned with multi-objective reinforcement learning (MORL), this paper presents MOMCTS, an extension of Monte-Carlo Tree Search to multi-objective sequential decision making. The known multi-objective indicator referred to as hyper-volume indicator is used to define an action selection criterion, replacing the UCB criterion in order to deal with multi-dimensional rewards. MO-MCTS is firstly c...
Today, attention to the tourism of historical contexts has been recognized as very important in order to promote socio-economic progress and to recognize the historical values and cultural identity of each region. Therefore, this study was written with the aim of identifying the causal pattern of tourism promotion criteria in the historical context of Tabriz. The present study is applied in t...
Introduction: One of the main challenges health system is improving quality healthcare services by adjusting costs. The right choice tools will bring economic savings besides excellent service quality. Since medical supplies are among fundamental and costly elements in providing services, expertise purchasing has become an important complex issue. This study aimed to prioritize criteria for sup...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
Bitcoin mining presents a significant economic incentive for efficient hashing and broadcast of data, both parameters stemming from the Proofs-of-Work used to advance the network. This incentive has led to the development of Bitcoin-specific application-specific integrated circuits (ASICs) and centralized mining pools, undermining the decentralized motivations behind Bitcoin’s design. In additi...
Urbanization lead a wide variety of difficulties that changes in the pattern of land use is the major consequence. One of the outcome of land use changes is ecological and biological capacity reduction or desertification. In this study, for determine of desertification due to urban development within the city of Mashhad, was used Iranian mothod (IMDPA). The land use map of this area was prepare...
Robustness aspects of nested balanced incomplete block designs against missing data have been investigated using connectedness and efficiency criteria. Sufficient condition for robustness of a design has been obtained for the loss of any m observations, using connectedness criterion. Designs robust against the loss of any m observations belonging to one sub-block, loss of any two observations b...
Background and Aim: Cardiovascular fitness is considered as an important indicator of health so that there is a clear relationship between the level of cardiovascular fitness and risk factors for heart disease. This indicator can be measured objectively and accurately by running. The aim of this study was to investigate the relationship between anthropometric indices and cardiovascular fitness ...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
