+### About our Multi-dialect-Arabic-BERT model
+Instead of training the Multi-dialect Arabic BERT model from scratch, we initialized the weights of the model using [Arabic-BERT](https://github.com/alisafaya/Arabic-BERT) and trained it on 10M arabic tweets from the unlabled data of [The Nuanced Arabic Dialect Identification (NADI) shared task](https://sites.google.com/view/nadi-shared-task).

+    year={2020},
+    eprint={2007.05612},
+    archivePrefix={arXiv},
+    primaryClass={cs.CL}
+}
+```
+
+### Usage
+The model weights can be loaded using `transformers` library by HuggingFace.
+
+```python
+from transformers import AutoTokenizer, AutoModel
+
+tokenizer = AutoTokenizer.from_pretrained("bashar-talafha/multi-dialect-bert-base-arabic")
+model = AutoModel.from_pretrained("bashar-talafha/multi-dialect-bert-base-arabic")
+```
+
+Example using `pipeline`:
+
+```python
+from transformers import pipeline
+
+fill_mask = pipeline(
+    "fill-mask",
+    model="bashar-talafha/multi-dialect-bert-base-arabic ",
+    tokenizer="bashar-talafha/multi-dialect-bert-base-arabic "
+)
+
+fill_mask(" سافر الرحالة من مطار [MASK] ")
+```
+```
+[{'sequence': '[CLS] سافر الرحالة من مطار الكويت [SEP]', 'score': 0.08296813815832138, 'token': 3226},
+ {'sequence': '[CLS] سافر الرحالة من مطار دبي [SEP]', 'score': 0.05123933032155037, 'token': 4747},

+ {'sequence': '[CLS] سافر الرحالة من مطار القاهرة [SEP]', 'score': 0.03234650194644928, 'token': 4003},
+ {'sequence': '[CLS] سافر الرحالة من مطار الرياض [SEP]', 'score': 0.02606341242790222, 'token': 2200}]
