Model description
The roberta-base-ca-v2-massive is a Intent Classification 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.
Intended uses and limitations
The roberta-base-ca-v2-massive model can be used for intent prediction in plain text sentences. It can be used in combination with an Automatic Speech Recognition model in order to implement a Voice Assistant. 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-massive")
example = "m'agraden les cançons del serrat"
intent = nlp(example)
pprint(intent)
Limitations and bias
At the time of submission, no measures have been taken to estimate the bias embedded in the model. However, we are well aware that our models may be biased since the corpora have been collected using crawling techniques on multiple web sources. We intend to conduct research in these areas in the future, and if completed, this model card will be updated.
Training
Training data
We used the Catalan split of the MASSIVE dataset for training and evaluation.
Training procedure
The model was trained with a batch size of 16 and a learning rate of 5e-5 for 20 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 the weighted F1 score.
Evaluation results
We evaluated the roberta-base-ca-v2-massive on the MASSIVE test set obtaining a weighted F1 score of 87.03.
