The base value indicates the average of all predictions in the dataset of the given chemistry. The red or blue color of the arrows in these plots indicates whether the associated feature, with the specified value and unit, pushes the prediction to a higher or lower value relative to this base value. The magnitude of each feature's contribution is indicated by the size of the corresponding arrow. When all these arrow lengths are added to the base value, with the respective sign given by the color, the final prediction is obtained. For the selected experiment with Graphite, we have a major impact of the AM wt.%, roll gap and the comma gap by pushing the prediction to the negative side of the base value, while the solid content pushes it to the positive side.
