Finetune ST5 & available models

[Chroner Ventiroso]

I am writing in regards to the ST5 model.

I read the relevant paper, I would like to finetune the base version. I am interested in the STS task. I assume the mean encoder would work best.

I would appreciate it if one can link me to the code or give me some pointers.

Moreover, can I confirm that the models on the page are the fine-tuned ones?

If so are they on the combined NLI + CommonQA?

Many thanks,

Phil
