Описание модели:

The underlying model (contains 560M parameters) was pre-trained by Facebook on the CC100 multi-lingual dataset (Russian included). We further fine-tune the pre-trained model separately for each RussianSuperGLUE task. For LiDiRus we start with TERRa-finetuned model. For RWSD we use the majority class baseline. For each task we submit best-performing checkpoint (saving each epoch) based on validation metrics.
