# NusaBERT Base
|
|
|
|
| 27 |
|
| 28 |
+
NusaBERT Base is a multilingual encoder-based language model based on the [BERT](https://arxiv.org/abs/1810.04805) architecture. We conducted continued pre-training on open-source corpora of [sabilmakbar/indo_wiki](https://huggingface.co/datasets/sabilmakbar/indo_wiki), [acul3/KoPI-NLLB](https://huggingface.co/datasets/acul3/KoPI-NLLB), and [uonlp/CulturaX](https://huggingface.co/datasets/uonlp/CulturaX). On a held-out subset of the corpus, our model achieved:
|
| 29 |
|
| 30 |
+
- `eval_accuracy`: 0.6866
|
| 31 |
+
- `eval_loss`: 1.4876
|
| 32 |
+
- `perplexity`: 4.4266
|
|
|
|
| 33 |
|
| 34 |
+
This model was trained using the [🤗Transformers](https://github.com/huggingface/transformers) PyTorch framework. All training was done on an NVIDIA H100 GPU. [LazarusNLP/NusaBERT-base](https://huggingface.co/LazarusNLP/NusaBERT-base) is released under Apache 2.0 license.
