The experimental data of the paper cannot be reproduced

[chinahappyking]

hi, guo I have tried many times. The following results are always the same, which is far from the results in the paper. Is there any difference between the results in the paper and the code?

Can you add a wechat private chat?

dataset: hdfs git branch: main ==================== logbert ==================== best threshold: 0, best threshold ratio: 0.0 TP: 7602, TN: 549880, FP: 3488, FN: 3045 Precision: 68.55%, Recall: 71.40%, F1-measure: 69.95%

I have the same issue. Did you end up can reproduce the results?

I just tried and have the same results:

best threshold: 0, best threshold ratio: 0.0 TP: 7643, TN: 549806, FP: 3562, FN: 3004 Precision: 68.21%, Recall: 71.79%, F1-measure: 69.95%

I haven't looked (deeply) into the code so far, but is the training data really limited to n=4855, as the code in line 122 in file data_process.py seems to indicate?

generate_train_test(log_sequence_file, n=4855)

How can I train for better results?

I removed n=4855 from the described code line in the previous comment and now I have a lot more training data available. I‘ll post about the results again.

Here are my results after applying the above changes:

best threshold: 0, best threshold ratio: 0.0 TP: 6996, TN: 390662, FP: 95, FN: 3651 Precision: 98.66%, Recall: 65.71%, F1-measure: 78.88%

Recall and F1 are still lower than in the paper, which were P=87.02, R=78.10, and F1=82.32 Caveat> I stopped training after 60 epochs, so this could be a reason for the underperforming values.

One more, after finishing training with a batch size of 512 with HDFS, val loss=0.183, train loss=0.178, 135 epochs, takes about 35 minutes on a RTX 3090.

best threshold: 0, best threshold ratio: 0.0 TP: 7583, TN: 390484, FP: 273, FN: 3064 Precision: 96.52%, Recall: 71.22%, F1-measure: 81.97%

Here is my result, training with a batch size of 512 with HDFS, val loss=0.537, train loss=0.451, 87 epochs, takes about 39 minutes on a RTX 3090.

best threshold: 0, best threshold ratio: 0.0 TP: 7908, TN: 389836, FP: 921, FN: 2739 Precision: 89.57%, Recall: 74.27%, F1-measure: 81.21% elapsed_time: 561.5744488239288
