đ bat-eng Translation Model
This is a translation model that translates from Baltic languages to English. It provides various performance benchmarks and detailed system information.
đ Quick Start
The bat-eng model is designed for translating Baltic languages to English. You can download the original weights and test set translations from the provided links below.
⨠Features
- Language Support: Supports multiple Baltic languages (lav, lit, ltg, prg_Latn, sgs) as source languages and English as the target language.
- Model Type: Utilizes a transformer model for translation.
- Pre - processing: Applies normalization and SentencePiece (spm32k, spm32k) for pre - processing.
đĻ Installation
There is no specific installation steps provided in the original document. However, you can download the model weights from the following link:
