Left column: The real relative abundances are indicated by the black points alongside the model predictions from both the train, validation, and test datasets, indicated by red, yellow, and green points, respectively. The model training and evaluation was done in windows of 10 samples predicting 10 samples into the future. The models used here have been trained on graph clusters. Right column: observed (real historic) values plotted against the predicted values with two different linear regression lines added: A linear regression between the observed and predicted relative abundance values (blue), and a 1.0-slope line (black) to represent the theoretical perfect prediction. The R2 values of each model are indicated in the top left corner, calculated based on the residuals of the linear regression model fitted to the data as well as the 1.0-slope line, respectively.
