Fig. 2: Correlation within the dataset visualized in a heatmap.

From: Accelerating the prediction of CO2 capture at low partial pressures in metal-organic frameworks using new machine learning descriptors

Fig. 2

Pearson correlation (r) heat-map of descriptors and target variable where the correlation between each pair of features can be found at the intersection of their respective column–row intersection. The values of the correlation are color-coded according to the scale shown to the right of the heat-map.
