# indoSBERT-large

This is a [sentence-transformers](https://www.SBERT.net) model: It maps sentences & paragraphs to a 256 dimensional dense vector space and can be used for tasks like clustering or semantic search.

IndoSBERT is a modification of `https://huggingface.co/indobenchmark/indobert-large-p1` that has been fine-tuned using the siamese network scheme inspired by SBERT (Reimers et al., 2019). 
This model was fine-tuned with the STS Dataset (2012-2016) which was machine-translated into Indonesian languange.

This model can provide meaningful semantic sentence embeddings for Indonesian sentences.

## Usage (Sentence-Transformers)

Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:

```
pip install -U sentence-transformers
```

Then you can use the model like this:

```python
from sentence_transformers import SentenceTransformer
sentences = ["Komposer favorit saya adalah Joe Hisaishi", "Sapo tahu enak banget"]

model = SentenceTransformer('denaya/indoSBERT-large')
embeddings = model.encode(sentences)
print(embeddings)
```



## Training

**DataLoader**:

`torch.utils.data.dataloader.DataLoader` of length 1291 with parameters:
```
{'batch_size': 16, 'sampler': 'torch.utils.data.sampler.RandomSampler', 'batch_sampler': 'torch.utils.data.sampler.BatchSampler'}
```

**Loss**:

`sentence_transformers.losses.CosineSimilarityLoss.CosineSimilarityLoss`
