What is opus-mt-tc-big-en-es?
opus-mt-tc-big-en-es is a state-of-the-art neural machine translation model developed by Helsinki-NLP for translating text from English to Spanish. It's part of the OPUS-MT project, which aims to make high-quality translation models accessible globally. The model is built using the Marian NMT framework and later converted to PyTorch using the Hugging Face transformers library.
Implementation Details
The model utilizes a transformer-big architecture and is trained on the opusTCv20210807+bt dataset. It implements SentencePiece tokenization with a 32k vocabulary for both source and target languages. The model has demonstrated impressive performance across various benchmark datasets, particularly achieving a BLEU score of 57.2 on the Tatoeba test set.
