Figure 4: Examples for estimation of points in time. Plotted points present computed correlation coefficients of the point in time we intend to estimate with all available samples of the training set. Each color illustrates one different patient. The average of the selected points in time with the highest correlation from each patient of the training set is displayed as a blue line representing the resulting estimated time. A) Estimated point in time (blue line) is almost identical to the real point in time (1.8h; violet line) B) Estimated point in time (blue line) is deviating from the real point in time (30.2 h; violet line) [13].
