Fig. 5. Performance of STEM+ in 2086 videos.
a Receiver operator characteristic (ROC) curves and area under the receiver operating characteristic curve (AUC) for spatial stream model (AUC = 0.76), temporal stream model (AUC = 0.78), and ensemble model STEM+ (AUC = 0.79). b The implantation outcomes of the transferred blastocysts in the validation dataset. A total of 160 embryos were predicted as usable blastocysts by STEM+ (green), and another 49 embryos were predicted as unusable blastocysts by STEM+ (orange). I implanted, F failed.
