Model description

The roberta-base-ca-v2-cased-te is a Textual Entailment (TE) 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).

Intended Uses and Limitations

roberta-base-ca-v2-cased-te model can be used to recognize Textual Entailment (TE). The model is limited by its training dataset and may not generalize well for all use cases.

How to Use

Here is how to use this model:

from transformers import pipeline
from pprint import pprint

nlp = pipeline("text-classification", model="projecte-aina/roberta-base-ca-v2-cased-te")
example = "M'agrada el sol i la calor. </s></s> A la Garrotxa plou molt."

te_results = nlp(example)
pprint(te_results)

Training

Training data

We used the TE dataset in Catalan called TECA for training and evaluation.

Training Procedure

The model was trained with a batch size of 16 and a learning rate of 5e-5 for 5 epochs. We then selected the best checkpoint using the downstream task metric in the corresponding development set and then evaluated it on the test set.

Evaluation

Variable and Metrics

This model was finetuned maximizing accuracy.

Evaluation results

We evaluated the roberta-base-ca-cased-te on the TECA test set against standard multilingual and monolingual baselines:

Model	TECA (Accuracy)
roberta-base-ca-v2-cased-te	83.14
BERTa	79.26
mBERT	74.63
XLM-RoBERTa	33.30
