Feature importance and decision boundary using the SVM. (a) Optimal number of features that best classified both groups. (b) Feature importance to select the features that best discriminated between both groups. The importance of the feature represented how important the metabolites (i.e., features) were under the influence of acute restraint stress as a quantified quantity. (c) Three-dimensional decision boundary with Ala, Glu, and NAA.
