Romanian DistilBERT
This repository contains the uncased Romanian DistilBERT (named Distil-RoBERT-base in the paper). The teacher model used for distillation is: readerbench/RoBERT-base.
The model was introduced in this paper. The adjacent code can be found here.
Usage
from transformers import AutoTokenizer, AutoModel
# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained("racai/distilbert-base-romanian-uncased")
model = AutoModel.from_pretrained("racai/distilbert-base-romanian-uncased")
# tokenize a test sentence
input_ids = tokenizer.encode("aceasta este o propoziție de test.", add_special_tokens=True, return_tensors="pt")
# run the tokens trough the model
outputs = model(input_ids)
print(outputs)
Model Size
It is 35% smaller than its teacher RoBERT-base
.
Model | Size (MB) | Params (Millions) |
---|---|---|
RoBERT-base | 441 | 114 |
distilbert-base-romanian-cased | 282 | 72 |
Evaluation
We evaluated the model in comparison with the RoBERT-base on 5 Romanian tasks:
- UPOS: Universal Part of Speech (F1-macro)
- XPOS: Extended Part of Speech (F1-macro)
- NER: Named Entity Recognition (F1-macro)
- SAPN: Sentiment Anlaysis - Positive vs Negative (Accuracy)
- SAR: Sentiment Analysis - Rating (F1-macro)
- DI: Dialect identification (F1-macro)
- STS: Semantic Textual Similarity (Pearson)
Model | UPOS | XPOS | NER | SAPN | SAR | DI | STS |
---|---|---|---|---|---|---|---|
RoBERT-base | 98.02 | 97.15 | 85.14 | 98.30 | 79.40 | 96.07 | 81.18 |
distilbert-base-romanian-uncased | 97.12 | 95.79 | 83.11 | 98.01 | 79.58 | 96.11 | 79.80 |
