# Pretrained BART in Korean

This is pretrained BART model with multiple Korean Datasets.

I used multiple datasets for generalizing the model for both colloquial and written texts.

The training is supported by [TPU Research Cloud](https://sites.research.google/trc/) program.

The script which is used to pre-train model is [here](https://github.com/cosmoquester/transformers-bart-pretrain).

When you use the reference API, you must wrap the sentence with `[BOS]` and `[EOS]` like below example.

```
[BOS] 안녕하세요? 반가워요~~ [EOS]
```

You can also test mask filling performance using `[MASK]` token like this.
```
[BOS] [MASK] 먹었어? [EOS]
```
