Results of Trec dataset on Roberta-large(K=512) with MeZO(LoRA)

[Yanjun-Zhao]

I use the grid research below but couldn't reproduce the result of the paper. (I have update the code for WD and successfully reproduce the result on SST2)

TASK=trec K=512 SEED=42 BS=64 WD=0.1 LR=1e-4/5e-5/1e-5 EPS=1e-3 MODEL=roberta-large EXTRA_TAG=lora bash mezo.sh --apply_lora --lora_r 8 --lora_alpha 16

Here is my produced result but paper result is Accuracy=95.

LR | Accuracy
1e-4 | 57.4
5e-5 | 60
1e-5 | 58.2

Hi,

There was a small bug in incorporating weight decay in the code and now it is fixed. Please try again!

[Yanjun-Zhao]

thanks for your reply!
But I have used the updated code and failed in Trec dataset.

Which commit are you using? Also, by fail you mean not being able to reproduce the result or there was a runtime error?

[Yanjun-Zhao]

I use the code with param.data = param.data - self.args.learning_rate * (projected_grad * z + self.args.weight_decay * param.data).
I cann't reproduce the result with TASK=trec K=512 SEED=42 BS=64 WD=0.1 LR=1e-4/5e-5/1e-5 EPS=1e-3 MODEL=roberta-large EXTRA_TAG=lora bash mezo.sh --apply_lora --lora_r 8 --lora_alpha 16. Not runtime error.

Hi,

Can you post the results you get with this experiment? Also, note that our reported results are averaged over five seeds following this paper's setting. The five seeds are 13 21 42 87 100.

@Yanjun-Zhao We were not able to reproduce the results of Roberta-large either. You mentioned that "I have update the code for WD and successfully reproduce the result on SST2". Do you mean that you used the code after this fix 552cb1b, and would you mind sharing the command and parameters you used?

Thanks a lot!

@gaotianyu1350 Hi we have the same issue as well. Would you mind sharing the code and configurations for reproduction?

[gaotianyu1350]

@hxixixh can you post the configuration you used and the results you got?
