In the non-overlap case, where each variable belongs to only one group, estimation of parameters and selection of important variables can be conducted via the minimization of (1) iteratively w.r.t.
It is then safe to conclude that SVMs alone are not able to perform a good optimization, and by combining with a variable selection step we can obtain a minimum subset of important variables to train a faster and more robust model, yielding better prediction performance.
Using a reduced set of important variables (i.e. reducing the dimensionality of input space by the variable selection procedure) results in support vector machines with better performance.
Our selection of important climatic variables was informed by crop yield results, but we did not directly model crop yield or the influence of enhanced atmospheric carbon dioxide concentrations on plant growth.
Table 1 shows a selection of demographic variables used.
It releases time series for a selection of National Accounts variables, including GDP, GFCF, industry-level VA and gross output.
Using machine learning methods allows the selection of the most important variables for further visualization (see below), interpretation and follow-up experiments in the laboratory.
Bayesian model averaging [26, 27] has been proposed to handle the skewness of cost variables or for the selection of important predictors, respectively, but simultaneous handling of skewness, heteroscedasticity and adjustment for confounding factors can be challenging.
