# Bahasa GPT2 Model

Pretrained GPT2 117M model for Malay.

## Pretraining Corpus

`gpt2-117M-bahasa-cased` model was pretrained on ~0.9 Billion words. We trained on standard language structure only, and below is list of data we trained on,

1. [dumping wikipedia](https://github.com/huseinzol05/Malaya-Dataset#wikipedia-1).
2. [local news](https://github.com/huseinzol05/Malaya-Dataset#public-news).
3. [local parliament text](https://github.com/huseinzol05/Malaya-Dataset#parliament).
4. [local singlish/manglish text](https://github.com/huseinzol05/Malaya-Dataset#singlish-text).
5. [IIUM Confession](https://github.com/huseinzol05/Malaya-Dataset#iium-confession).
6. [Wattpad](https://github.com/huseinzol05/Malaya-Dataset#wattpad).
7. [Academia PDF](https://github.com/huseinzol05/Malaya-Dataset#academia-pdf).
8. [Common-Crawl](https://github.com/huseinzol05/malaya-dataset#common-crawl).

Preprocessing steps can reproduce from here, [Malaya/pretrained-model/preprocess](https://github.com/huseinzol05/Malaya/tree/master/pretrained-model/preprocess).

## Pretraining details

- This model was trained using GPT2's github [repository](https://github.com/openai/gpt-2) on a V3-8 TPU.
- All steps can reproduce from here, [Malaya/pretrained-model/gpt2](https://github.com/huseinzol05/Malaya/tree/master/pretrained-model/gpt2).

## 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 GPT2Tokenizer, GPT2Model

model = GPT2Model.from_pretrained('huseinzol05/gpt2-117M-bahasa-cased')
tokenizer = GPT2Tokenizer.from_pretrained(
    'huseinzol05/gpt2-117M-bahasa-cased',
)
```

## Example using GPT2LMHeadModel

```python
from transformers import GPT2Tokenizer, GPT2LMHeadModel

tokenizer = GPT2Tokenizer.from_pretrained('huseinzol05/gpt2-117M-bahasa-cased')
model = GPT2LMHeadModel.from_pretrained(
    'huseinzol05/gpt2-117M-bahasa-cased', pad_token_id = tokenizer.eos_token_id
)

input_ids = tokenizer.encode(
    'penat bak hang, macam ni aku takmau kerja dah', return_tensors = 'pt'
)
sample_outputs = model.generate(
    input_ids,
    do_sample = True,
    max_length = 50,
    top_k = 50,
    top_p = 0.95,
    num_return_sequences = 3,
)

print('Output:\n' + 100 * '-')
for i, sample_output in enumerate(sample_outputs):
    print(
        '{}: {}'.format(
            i, tokenizer.decode(sample_output, skip_special_tokens = True)
        )
    )
```

Output is,

```text
Output:
----------------------------------------------------------------------------------------------------
0: penat bak hang, macam ni aku takmau kerja dah jadi aku pernah beritahu orang.
Ini bukan aku rasa cam nak ajak teman kan ni.
Tengok ni aku dah ada adik-adik & anak yang tinggal dan kerja2 yang kat sekolah.
1: penat bak hang, macam ni aku takmau kerja dah.
Takleh takleh nak ambik air.
Tgk jugak aku kat rumah ni.
Pastu aku nak bagi aku.
So aku dah takde masalah pulak.
Balik aku pun
2: penat bak hang, macam ni aku takmau kerja dah macam tu.
Tapi semua tu aku ingat cakap, ada cara hidup ni yang kita kena bayar.. pastu kita tak mampu bayar.. kan!!
Takpelah, aku nak cakap, masa yang
