stsb-m-mt-ca-distilbert-base-uncased

distilbert-base-uncased trained for Semantic Textual Similarity in Catalan

This is a test model that was fine-tuned using the Catalan traduction of Spanish datasets from stsb_multi_mt in order to understand and benchmark STS models.

Model and training data description

This model was built taking distilbert-base-uncased and training it on a Semantic Textual Similarity task using a modified version of the training script for STS from Sentece Transformers (the modified script is included in the repo). It was trained using the Spanish datasets from stsb_multi_mt which are the STSBenchmark datasets automatically translated to other languages using deepl.com. and salt.gva.es. Refer to the dataset repository for more details.

Intended uses & limitations

This model was built just as a proof-of-concept on STS fine-tuning using Catalan data and no specific use other than getting a sense on how this training works.

How to use

You may use it as any other STS trained model to extract sentence embeddings. Check Sentence Transformers documentation.

Training procedure

Use the included script to train in Catalan the base model. You can also try to train another model passing it's reference as first argument. You can also train in some other language of those included in the training dataset.

Evaluation results

Evaluating distilbert-base-uncased on the Catalan test dataset before training results in:

Cosine-Similarity :	Pearson: 0.3180	Spearman: 0.4014

While the fine-tuned version with the defaults of the training script and the Catalan training dataset results in:

Cosine-Similarity :	Pearson: 0.7368	Spearman: 0.7288
