The results of this experiment are shown in Table . We observe that when the Synt-80k dataset is used, the sequence level accuracy (SLA) is around 60%. However, when it is not used, the SLA drops dramatically to between 0% and 5%, which will be unusable in any real-world setting. Interestingly, the choice of pre-training for the encoder (either ImageNet or SwinOCSR) does not seem to affect the results significantly.
