Figure 8. Results for melodic uncertainty.

(A) Relationship between and distribution of surprise and uncertainty estimates from the Music Transformer (context length of eight notes). (B) Cross-validated predictive performance for the Baseline +surprise model (top), and for models with added uncertainty regressor (middle) and the interaction between surprise and uncertainty (SxU, bottom). Adding uncertainty and/or the interaction between surprise and uncertainty (SxU) did not improve but worsen the predictive performance on the MEG data.
