Fig. 4: Performance evaluation and optimization of predictive models.

From: Novel machine learning driven design strategy for high strength Zn Alloys optimization with multiple constraints

Fig. 4

Mean and standard deviation of R² for the three ensemble algorithms under different training set ratios: (a) UTS; (b) EL; (c) Hardness. Predictive performance of the optimized model: (d) UTS; (e) EL; (f) Hardness. The red points represent the sample points from the training set, and the green points represent the sample points from the test set.
