the results of distillation of multilingual models is poor #1068

Open ScottishFold007 opened 3 years ago

ScottishFold007 commented 3 years ago

Inspired by < Making Monolingual Sentence Embeddings Multilingual using Knowledge Distillation > I expanded the original English-only model to support Chinese,I use the script - make_multilingual.py，and modified some settings,but I got poorer results, and here are some key training codes: image image image image image Accuracy src2trg and Accuracy trg2src was getting increasingly smaller ，and embedding similarity has deteriorating results...

So I want ask you - 1、What are the possible reasons for the above situation? 2、Can you tell me how you train ‘paraphrase-multilingual-mpnet-base-v2’？It works really well on Chinese！！！

Thank you in advance！

The same script was used to train the multilingual models. From your screenshot I cannot see an issue.

Sometimes restarting helps. Transformer networks are known to diverge in some cases. Simply restarting helps.

Thank you, nreimers. But I've restarted many times with the same result, which frustrates me and I really don't know what the problem is...
