Figure 6.—
Average prediction accuracy of ɛ-SVR and BLP prediction models over 100 iterations of the simulation routine for varying levels of the minimum required contrast precision CDmin, expressed as a percentile of the sampled CD values ranging from 0 to 0.875 and the number of genotyped inbred lines. The height of each point in the wireframe represents the prediction accuracy obtained by ɛ-SVR and BLP when training on the optimal selection of hybrids under the constraints imposed by the levels of the two independent variables. Prediction accuracy is expressed as the average squared Pearson correlation between the simulated and the predicted genotypic values of the hybrids. The interval at the bottom of each wireframe provides the minimum and maximum standard error of the mean. The scales of the vertical axes are comparable only within the same heritability level.
