+# Bahasa ELECTRA Model
+
+Pretrained ELECTRA base language model for Malay and Indonesian. 
+
+## Pretraining Corpus
+
+`electra-base-generator-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,
+
+1. [dumping wikipedia](https://github.com/huseinzol05/Malaya-Dataset#wikipedia-1).
+2. [local instagram](https://github.com/huseinzol05/Malaya-Dataset#instagram).
+3. [local twitter](https://github.com/huseinzol05/Malaya-Dataset#twitter-1).
+4. [local news](https://github.com/huseinzol05/Malaya-Dataset#public-news).
+5. [local parliament text](https://github.com/huseinzol05/Malaya-Dataset#parliament).
+6. [local singlish/manglish text](https://github.com/huseinzol05/Malaya-Dataset#singlish-text).
+7. [IIUM Confession](https://github.com/huseinzol05/Malaya-Dataset#iium-confession).
+8. [Wattpad](https://github.com/huseinzol05/Malaya-Dataset#wattpad).
+9. [Academia PDF](https://github.com/huseinzol05/Malaya-Dataset#academia-pdf).
+
+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 Google ELECTRA's github [repository](https://github.com/google-research/electra) on v3-8 TPU.
+- All steps can reproduce from here, [Malaya/pretrained-model/electra](https://github.com/huseinzol05/Malaya/tree/master/pretrained-model/electra).
+
+## 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 ElectraTokenizer, ElectraModel
+
+model = ElectraModel.from_pretrained('huseinzol05/electra-base-generator-bahasa-cased')
+tokenizer = ElectraTokenizer.from_pretrained(
+    'huseinzol05/electra-base-generator-bahasa-cased',
+    do_lower_case = False,
+)
+```
+
+## Example using AutoModelWithLMHead
+
+```python
+from transformers import ElectraTokenizer, AutoModelWithLMHead, pipeline
+
+model = AutoModelWithLMHead.from_pretrained('huseinzol05/electra-base-generator-bahasa-cased')
+tokenizer = ElectraTokenizer.from_pretrained(
+    'huseinzol05/electra-base-generator-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': 0.08424834907054901,
+  'token': 3255},
+ {'sequence': '[CLS] makan ayam dengan rendang [SEP]',
+  'score': 0.064150370657444,
+  'token': 6288},
+ {'sequence': '[CLS] makan ayam dengan nasi [SEP]',
+  'score': 0.033446669578552246,
+  'token': 2533},
+ {'sequence': '[CLS] makan ayam dengan kucing [SEP]',
+  'score': 0.02803465723991394,
+  'token': 3577},
+ {'sequence': '[CLS] makan ayam dengan telur [SEP]',
+  'score': 0.026627106592059135,
+  'token': 6350}]
+```
