Figure 2.

(Top) A figure showing the multitask seq2seqmodel predicting the 20 min glucose trajectory for a 95% prediction interval (lightly shaded blue area) over a 24-h period. The estimated glucose level (red dashed line) closely follows the reference glucose level from the CGM (green line) except during unannounced meals. In the instance of an unannounced meal—such as dinner just before 9 p.m.—a significant and persistent deviation in glucose trajectory from estimated trajectory occurs (shown on the right) which leads to a meal detection and estimation. (Bottom) The unannounced meal and reconstructed estimated meal. Certain meals such as the small snack between 3 p.m. and 6 p.m. are not detected as reliably since they only result in a non-significant deviation in the glucose trajectory.
