Figure 3. The determination coefficient distribution calculated on the grid of parameters. An acceptable values of the hyperparameters corresponds to area where determination coefficient value exceeds level 0.7. To build the model, the values determined by the intersection point of the median and hypotenuse of the triangle formed by the axes of coordinates and the straight line approximating the level 0.7 are chosen.
