Freight demand is a highly variable process over economic and industrial structure, accurate freight forecasting the basis of transportation planning. In order to clarify influencing factors volume so as analyze predict change trend accurately, this paper analyzes impact changes in economic, complete consumption coefficients on demand, through constructing an input-output model for value analys...
Well known to the machine learning community, random feature model is a parametric approximation kernel interpolation or regression methods. It typically used approximate functions mapping finite-dimensional input space real line. In this paper, we instead propose methodology for use of as data-driven surrogate operators that map an Banach output space. Although quite general, consider defined ...
in this study, several artificial neural networks (anns) were developed to estimate seed and grain corn yields in parsabad moghan, iran. the data was collected by a face-to-face interview method from 144 corn farms during 2011. the energy ratios for seed and grain corns were calculated as 0.89 and 2.65, respectively. several multilayer perceptron anns with six neurons in the input layer and one...
Data envelopment analysis (DEA) has been a very popular method for measuring and benchmarking relative efficiency of peer decision making units (DMUs) with multiple input and outputs. Traditional data envelopment analysis (DEA) models require crisp input and output data. In real world situations, however, crisp input and output data may not always be available, especially when a set of decision...
