+# ✨ bert-restore-punctuation
+[![forthebadge](https://forthebadge.com/images/badges/gluten-free.svg)]()
+
+This a bert-base-uncased model finetuned for punctuation restoration on [Yelp Reviews](https://www.tensorflow.org/datasets/catalog/yelp_polarity_reviews). 
+
+The model predicts the punctuation and upper-casing of plain, lower-cased text. An example use case can be ASR output. Or other cases when text has lost punctuation.
+
+This model is intended for direct use as a punctuation restoration model for the general English language. Alternatively, you can use this for further fine-tuning on domain-specific texts for punctuation restoration tasks.
+
+Model restores the following punctuations -- **[! ? . , - : ; ' ]**
+
+The model also restores the upper-casing of words.
+
+-----------------------------------------------
+## 🚋 Usage
+**Below is a quick way to get up and running with the model.**
+1. First, install the package.
+```bash
+pip install rpunct
+```
+2. Sample python code.
+```python
+from rpunct import RestorePuncts
+# The default language is 'english'
+rpunct = RestorePuncts()
+rpunct.punctuate("""in 2018 cornell researchers built a high-powered detector that in combination with an algorithm-driven process called ptychography set a world record
+by tripling the resolution of a state-of-the-art electron microscope as successful as it was that approach had a weakness it only worked with ultrathin samples that were
+a few atoms thick anything thicker would cause the electrons to scatter in ways that could not be disentangled now a team again led by david muller the samuel b eckert
+professor of engineering has bested its own record by a factor of two with an electron microscope pixel array detector empad that incorporates even more sophisticated
+3d reconstruction algorithms the resolution is so fine-tuned the only blurring that remains is the thermal jiggling of the atoms themselves""")

+```
+
+**This model works on arbitrarily large text in English language and uses GPU if available.**
+
+-----------------------------------------------
+## 📡 Training data
+
+Here is the number of product reviews we used for finetuning the model:
+
+| Language | Number of text samples|
+| -------- | ----------------- |
+| English  | 560,000           |
+
+We found the best convergence around _**3 epochs**_, which is what presented here and available via a download.
+
+-----------------------------------------------
+## 🎯 Accuracy
+The fine-tuned model obtained the following accuracy on 45,990 held-out text samples:
+
+| Accuracy | Overall F1 | Eval Support |
+| -------- | ---------------------- | ------------------- |
+| 91%  | 90%                 | 45,990
+
+Below is a breakdown of the performance of the model by each label:
