 ## Training
-The model was trained with the parameters:
 
-**DataLoader**:
+rufimelo/Legal-SBERTimbau-sts-base-ma is based on Legal-BERTimbau-base which derives from [BERTimbau](https://huggingface.co/neuralmind/bert-base-portuguese-cased) base.
 
-`torch.utils.data.dataloader.DataLoader` of length 270 with parameters:
-```
-{'batch_size': 64, 'sampler': 'torch.utils.data.sampler.RandomSampler', 'batch_sampler': 'torch.utils.data.sampler.BatchSampler'}
-```
+Firstly, due to the lack of portuguese datasets, it was trained using multilingual knowledge distillation. 
+For the Multilingual Knowledge Distillation process, the teacher model was 'sentence-transformers/paraphrase-xlm-r-multilingual-v1', the supposed supported language as English and the language to learn was portuguese.
