    sion models. Multiple regression models and neural net-works are examined for a range of cities under different climate and ozone regimes, enabling a comparative study of the two approaches. Model comparison statistics indi-cate that neural network techniques are somewhat (but not dramatically) better than regression models for daily. The three techniques selected where linear regression analysis (LRA), classification and regression trees (CART) and artificial neural networks (ANN). The analysis illustrates that when the relationship between the independent and dependent variables is a linear one, that LRA is by: 3.

      In today’s global competitive environment, it is important to be able to evaluate the efficient use of a firms’ resources. The aim of this study is to predict the discard rate for headlight frames before the project of an automotive sub-industry firm in Bursa. For this prediction, the multilayer perceptron model, the radial basis function network model and multiple linear regression models Author: Vesile Sinem Arikan Kargi.   Deep learning techniques such as convolutional neural networks (CNNs) can potentially provide powerful tools for classifying, identifying, and predicting patterns in Cited by: 3.
