Examples of TSS classification of the optimal LR classifier trained with both the baseline and deep AE features. Patient #1 (deep white matter infarct) and patient #2 (cortical infarct) were correctly classified as having TSS<4.5hrs and showed clear mismatch between DWI and FLAIR. In patient #3, the mismatch between DWI and FLAIR was less obvious, but the classifier still classified correctly. Patient #4 was misclassified because there was a visible mismatch between DWI and FLAIR images, but clinical history determined TSS to be > 4.5hrs. In patient #5, the infarct was more conspicuous on DWI but essentially matched on FLAIR, and was also misclassified.
