+# BERT SMALL + Typo Detection ✍❌✍✔
+
+[BERT SMALL](https://huggingface.co/google/bert_uncased_L-4_H-512_A-8) fine-tuned on [GitHub Typo Corpus](https://github.com/mhagiwara/github-typo-corpus) for **typo detection** (using *NER* style)
+
+## Details of the downstream task (Typo detection as NER)
+
+- Dataset: [GitHub Typo Corpus](https://github.com/mhagiwara/github-typo-corpus) 📚
+
+- [Fine-tune script on NER dataset provided by Huggingface](https://github.com/huggingface/transformers/blob/master/examples/token-classification/run_ner_old.py) 🏋️‍♂️
+
+## Metrics on test set 📋
+
+|  Metric   |  # score  |
+| :-------: | :-------: |
+|    F1     | **89.12** |
+| Precision | **93.82** |
+|  Recall   | **84.87** |
+
+## Model in action 🔨
+
+Fast usage with **pipelines** 🧪
+
+```python
+from transformers import pipeline
+
+typo_checker = pipeline(
+    "ner",
+    model="mrm8488/bert-small-finetuned-typo-detection",
+    tokenizer="mrm8488/bert-small-finetuned-typo-detection"
+)
+
+result = typo_checker("here there is an error in coment")
+result[1:-1]
+
+# Output:
+[{'entity': 'ok', 'score': 0.9021041989326477, 'word': 'here'},
+ {'entity': 'ok', 'score': 0.7975626587867737, 'word': 'there'},
+ {'entity': 'ok', 'score': 0.8596242070198059, 'word': 'is'},
+ {'entity': 'ok', 'score': 0.7071516513824463, 'word': 'an'},
+ {'entity': 'ok', 'score': 0.943381130695343, 'word': 'error'},
+ {'entity': 'ok', 'score': 0.8047608733177185, 'word': 'in'},
+ {'entity': 'ok', 'score': 0.8240702152252197, 'word': 'come'},
+ {'entity': 'typo', 'score': 0.5004884004592896, 'word': '##nt'}]
+```
+
+It works🎉! we typed ```coment``` instead of ```comment```
+
+Let's try with another example
+
+```python
+result = typo_checker("Adddd validation midelware")
+result[1:-1]
+
+# Output:
+[{'entity': 'ok', 'score': 0.7128152847290039, 'word': 'add'},
+ {'entity': 'typo', 'score': 0.5388424396514893, 'word': '##dd'},
+ {'entity': 'ok', 'score': 0.94792640209198, 'word': 'validation'},
+ {'entity': 'typo', 'score': 0.5839331746101379, 'word': 'mid'},
+ {'entity': 'ok', 'score': 0.5195121765136719, 'word': '##el'},
+ {'entity': 'ok', 'score': 0.7222476601600647, 'word': '##ware'}]
+```
+Yeah! We typed wrong ```Add and middleware```
