Fig. 5: The machine learning model evaluation and correlation analysis results.

From: Rapid screening of the stability of polyacrylamide-based hydrogel coatings via droplet microarray analysis and interpretable machine learning

Fig. 5

Prediction accuracy (lower MSE value and higher R2 value represent higher accuracy) of SVR, ABR, GBR, ANN and GPR regression models for the Stab value of hydrogel coatings in a strong base, b strong acid and c mixed enzyme environments. d The flow chart showed the correlation screening process. e Pearson correlation coefficients between all molecular feature descriptors, where cyan and brown represented positive and negative correlations, respectively, and deeper colors indicated stronger correlations.
