The results of BERT-LSTM model is different from the paper

[aiishii]

Hello. Let me ask you a question.

I tried to build a BERT-LSTM model for your paper using Movie Reviews data, but I couldn't reproduce the paper results. My results are as follows. Training: train 0.925, validation 0.833, test 0.849 prediction: Performance AURPRC comprehensiveness sufficiency BERT-LSTM + Attention 0.829 0.463 0.223 0.141 BERT-LSTM + Simple Gradient 0.829 0.469 0.222 0.141 The performance in Table 4 of the paper is 0.974, and my result is 0.829, which is very different.

What I changed from the parameters listed in the README is that the predict batch size is 4 to 2 due to lack of memory. My environment is as follows: Memory 65G, GPU NVIDIA Tesla 32GB

Could you tell me if there are any parameter differences or any other differences from the paper experiments?

Hi, I tried to build bert_encoder_generator using Movie Reviews data, but I met with some issues. The training processes are normal, but the results on the validation data are always the same with fscore_NEG: 0.000 fscore_POS: 0.667. I try different bert learning rate with 5e-1, 5e-2, 5e-3, 5e-4, 5e-5. However, the results on the validation dataset are the same. Could you show me how to set parameters?

Hi, the Bert encoder generator model is extremely unstable hence it is not surprising that you are getting bad results. Could you try with word_emb_encoder_generator model ? Also try setting reinforce_loss_weight to 0 here https://github.com/successar/Eraser-Benchmark-Baseline-Models/blob/894bfba09e8966aec9b046ddc595d434504a4f90/Rationale_model/training_config/classifiers/bert_encoder_generator.jsonnet#L99 and see if you still get the same problem.
