Figure 1 Contour-based decision boundary matrix created by means of random forests model (a machine learning algorithm). Each scatter plot contains the data-points belonging to different classes (open access and non-open access) and colored contours depicting the predicted classes. Path diagram on the right side showed results of principal component analysis. The components were selected such that they clarify most of the variance in the original dataset.
