In order to further improve the ability of automatic feature extraction deep learning technology and better solve problem system recognition declining when number training samples is reduced or iterations reduced, this paper proposes a fisher-based convolutional neural network algorithm, which automatically obtains structural information face image with help algorithm then reduces weights reduc...

We present an application of the measure of total uncertainty on convex sets of probability distributions, also called credal sets, to the construction of classification trees. In these classification trees the probabilities of the classes in each one of its leaves is estimated by using the imprecise Dirichlet model. In this way, smaller samples give rise to wider probability intervals. Branchi...

according to the contradictory reports of researchers, tillers may have positive or negative effect on wheat yield. thus, this study was conducted to investigate the role of tillers on wheat yield under two row spacing of 12.5 and 25 cm and four plant densities of 125, 250, 375 and 500 plants per m2, at gorgan university of agricultural sciences and natural resources farm in anbare-ololum reign...

in this article we will try to investigate the market of luxury auto and for presenting some view of marketing programs, at first review the supply and demand of auto in market of iran. then we will recover the taste and behavior of costumers in this segment and list the effective factors in purchase decision and if they attend to the brands or not.  then with interview with experts using multi...

Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

We describe a method for pooling and sequencing DNA from a large number of individual samples while preserving information regarding sample identity. DNA from 576 individuals was arranged into four 12 row by 12 column matrices and then pooled by row and by column resulting in 96 total pools with 12 individuals in each pool. Pooling of DNA was carried out in a two-dimensional fashion, such that ...
