a question about results

[zkLyons]

Hello! I have a question to ask. I set the number of epochs to 200, and I initially thought that the overall trend of HR and NDCG would continuously increase with the increase in epochs. However, the final results showed that HR reached its highest value at epoch 6. After that, as the number of epochs increased, both HR and NDCG started to decrease. I would like to know if this situation is normal, and what might cause this result. I hope you can provide an explanation. Thank you!

Hello, @zkLyons
Maybe you should reduce the learning rate.
