Fig. 3: Predictions for unseen experiments to exceed Si/Al = 3.
From: Machine learning-assisted crystal engineering of a zeolite

Predictions for Si/Al ratio in different regions of input space. Each subplot varies two quantities at a time. a GH prediction (“rescaled 10-CV”) as crystallization time and Na2O change. b GH prediction (“rescaled 10-CV”) as SiO2 and Na2O change. c GH prediction (“rescaled 10-CV”) as crystallization time and crystallization temperature change. These three figures illustrate neighborhoods of entry 20, which was made using molar composition 12 SiO2: 1 Al2O3: 4 Na2O: 160 H2O, 100 °C for 5 days under static conditions; the arrow indicates (the projection of) the Si/Al gradient’s direction.
