Spanish scientific T5 model initialized from EN-T5-Sci using WECHSEL and a language-specific SentencePiece 32k tokenizer.
Model Details
This is one of the non-English scientific T5 transfer models from the paper. The model keeps the EN-T5-Sci Transformer weights and reinitializes the language-specific embeddings with WECHSEL using a target SentencePiece tokenizer.
WECHSEL resources: English fastText embeddings + Spanish fastText embeddings (es) with the spanish bilingual dictionary.
