legal_t5_small_multitask_cs_en model
Model on translating legal text from Cszech to English. It was first released in
this repository. The model is parallely trained on the three parallel corpus with 42 language pair
from jrc-acquis, europarl and dcep along with the unsupervised task where the model followed the task of prediction in a masked language model.
Model description
No pretraining is involved in case of legal_t5_small_multitask_cs_en model, rather the unsupervised task is added with all the translation task
to realize the multitask learning scenario.
Intended uses & limitations
The model could be used for translation of legal texts from Cszech to English.
How to use
Here is how to use this model to translate legal text from Cszech to English in PyTorch:
1from transformers import AutoTokenizer, AutoModelWithLMHead, TranslationPipeline

3pipeline = TranslationPipeline(
4model=AutoModelWithLMHead.from_pretrained("SEBIS/legal_t5_small_multitask_cs_en"),
5tokenizer=AutoTokenizer.from_pretrained(pretrained_model_name_or_path = "SEBIS/legal_t5_small_multitask_cs_en", do_lower_case=False,
6 skip_special_tokens=True),

Training data
The legal_t5_small_multitask_cs_en model (the supervised task which involved only the corresponding langauge pair and as well as unsupervised task where all of the data of all language pairs were available) model was trained on
JRC-ACQUIS,
EUROPARL, and
DCEP dataset consisting of 5 Million parallel texts.
Training procedure
The model was trained on a single TPU Pod V3-8 for 250K steps in total, using sequence length 512 (batch size 4096). It has a total of approximately 220M parameters and was trained using the encoder-decoder architecture. The optimizer used is AdaFactor with inverse square root learning rate schedule.
Preprocessing
An unigram model trained with 88M lines of text from the parallel corpus (of all possible language pairs) to get the vocabulary (with byte pair encoding), which is used with this model.
Pretraining
Evaluation results
When the model is used for translation test dataset, achieves the following results:
