Time prediction performance evaluation index MAE

[dgbsg]

Hi, thank you very much for your code. I successfully ran your code and got the results you gave.
However, I don't understand why MAE is used as a performance indicator for time prediction, because I found that pred_times and gold_times are quite different, and the prediction effect is not ideal. However, due to the computer system of MAE itself, the prediction results look good.

This doesn't matter as long as every body use this metric

MAE is a popular metric. However, I also found that the prediction ability is not that good as expected.
