IsSynth-Cars

Final Stanford Cars result

Test top-1 accuracy: 93.3466% (7,506/8,041 correct). Test macro-F1: 0.932806. Best validation accuracy: 93.3170% at epoch 27 (zero based); final validation accuracy: 92.4586%.

The 40-epoch run used validation to select the best checkpoint, then evaluated that checkpoint on the official 8,041-image test split. This numerical result was recovered and independently verified from the saved predictions and confusion matrix; no additional training or test pass was performed for this reporting update.
