Losses decrease quite slowly with custom dataset

[bbsvip]

I created a custom dataset and tried training with arch 5 with image size 512 but the loss decreased quite slowly. Is this normal, or is my data problem?

my loss Epoch:[001/200] Train Loss:99.721 | MAE:0.189 Valid Loss:82.747 | MAE:0.125 =============================Epoch:[002/200] Train Loss:91.156 | MAE:0.156 Valid Loss:91.560 | MAE:0.166 =============================Epoch:[003/200] Train Loss:91.532 | MAE:0.155 Valid Loss:78.634 | MAE:0.106 =============================Epoch:[004/200] Train Loss:86.963 | MAE:0.135 Valid Loss:76.247 | MAE:0.095 =============================Epoch:[005/200] Train Loss:85.692 | MAE:0.130 Valid Loss:74.397 | MAE:0.086 =============================Epoch:[006/200] Train Loss:85.188 | MAE:0.127 Valid Loss:74.988 | MAE:0.086 =============================Epoch:[007/200] Train Loss:84.972 | MAE:0.125 Valid Loss:73.414 | MAE:0.082 =============================Epoch:[008/200] Train Loss:83.838 | MAE:0.121 Valid Loss:75.131 | MAE:0.087 =============================Epoch:[009/200] Train Loss:83.403 | MAE:0.119

Sorry for the late reply. Did you try to decrease learning rate?
