Catalan BERTa-v2 (roberta-base-ca-v2) finetuned for Text Classification.

The roberta-base-ca-v2-cased-tc is a Text Classification (TC) model for the Catalan language fine-tuned from the roberta-base-ca-v2 model, a RoBERTa base model pre-trained on a medium-size corpus collected from publicly available corpora and crawlers (check the roberta-base-ca-v2 model card for more details).

Datasets

We used the TC dataset in Catalan called TeCla for training and evaluation.

Evaluation and results

We evaluated the roberta-base-ca-v2-cased-tc on the TeCla test set against standard multilingual and monolingual baselines:

Model	TeCla (Accuracy)
roberta-base-ca-v2-cased-tc	74.26
roberta-base-ca-cased-tc	73.65
mBERT	69.90
XLM-RoBERTa	70.14

For more details, check the fine-tuning and evaluation scripts in the official GitHub repository.
