There are three major strategies to form neural network ensembles. The simplest one is the Cross Validation strategy in which all members are trained with the same training data. Bagging and boosting strategies pro-duce perturbed sample from training data. This paper provides an ideal model based on two important factors: activation function and number of neurons in the hidden layer and based u...

effects of morph physiological characteristics on yield and yield components of corn grain were investigated. an experiment was conducted in the experimental field of abourayhan campus, university of tehran. the experimental design was a block in split plot arrangement with four replications. planting dates were as main factor with three levels (4th, 14th and 25th june) and four varieties (sing...

Results 712 (male 77.5%) patients were operated on, with 609 (85.54%) being isolated CABG and 103 (14.46%) combined CABG with AVR. Average age in isolated CABG and combined groups were 66 and 73 years respectively. Average additive EuroScores were 3.5 and 7.29. 21.6% cases were performed by trainee or staff grade surgeon. In hospital mortality was 0.16% in isolated CABG and 0% in CABG with AVR ...

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

in this study 18 forage corn (zea mays l.) hybrid varieties were evaluated based on rcbd with four replications in khorasan razavi agricultural and natural resources research centre, iran, on 2008-2009. result of analysis of variance showed that there was significantly difference between hybrids in forage yield, ear weight and ear to biomass ratio. results of hybrids mean comparison with duncan...
