# Bahasa Albert Model

Pretrained Albert tiny language model for Malay and Indonesian, 85% faster execution and 50% smaller than Albert base.

## Pretraining Corpus

`albert-tiny-bahasa-cased` model was pretrained on ~1.8 Billion words. We trained on both standard and social media language structures, and below is list of data we trained on,

## Pretraining details

- This model was trained using Google Albert's github [repository](https://github.com/google-research/ALBERT) on v3-8 TPU.
- All steps can reproduce from here, [Malaya/pretrained-model/albert](https://github.com/huseinzol05/Malaya/tree/master/pretrained-model/albert).

## Load Pretrained Model

You can use this model by installing `torch` or `tensorflow` and Huggingface library `transformers`. And you can use it directly by initializing it like this:  

```python
from transformers import AlbertTokenizer, AlbertModel

model = BertModel.from_pretrained('huseinzol05/albert-tiny-bahasa-cased')
tokenizer = AlbertTokenizer.from_pretrained(
    'huseinzol05/albert-tiny-bahasa-cased',
    do_lower_case = False,
)
```

## Example using AutoModelWithLMHead

```python
from transformers import AlbertTokenizer, AutoModelWithLMHead, pipeline

model = AutoModelWithLMHead.from_pretrained('huseinzol05/albert-tiny-bahasa-cased')
tokenizer = AlbertTokenizer.from_pretrained(
    'huseinzol05/albert-tiny-bahasa-cased',
    do_lower_case = False,
)
fill_mask = pipeline('fill-mask', model = model, tokenizer = tokenizer)
print(fill_mask('makan ayam dengan [MASK]'))
```

Output is,

```text
[{'sequence': '[CLS] makan ayam dengan ayam[SEP]',
  'score': 0.05121927708387375,
  'token': 629},
 {'sequence': '[CLS] makan ayam dengan sayur[SEP]',
  'score': 0.04497420787811279,
  'token': 1639},
 {'sequence': '[CLS] makan ayam dengan nasi[SEP]',
  'score': 0.039827536791563034,
  'token': 453},
 {'sequence': '[CLS] makan ayam dengan rendang[SEP]',
  'score': 0.032997727394104004,
  'token': 2451},
 {'sequence': '[CLS] makan ayam dengan makan[SEP]',
  'score': 0.031354598701000214,
  'token': 129}]
```
