+
+In this repository the MDZ Digital Library team (dbmdz) at the Bavarian State
+Library open sources a cased ELECTRA base model for Turkish 🎉
+
+# Turkish ELECTRA model
+
+We release a base ELEC**TR**A model for Turkish, that was trained on the same data as *BERTurk*.
+
+> ELECTRA is a new method for self-supervised language representation learning. It can be used to
+> pre-train transformer networks using relatively little compute. ELECTRA models are trained to
+> distinguish "real" input tokens vs "fake" input tokens generated by another neural network, similar to
+> the discriminator of a GAN.
+
+More details about ELECTRA can be found in the [ICLR paper](https://openreview.net/forum?id=r1xMH1BtvB)
+or in the [official ELECTRA repository](https://github.com/google-research/electra) on GitHub.
+
+## Stats
+
+The current version of the model is trained on a filtered and sentence
+segmented version of the Turkish [OSCAR corpus](https://traces1.inria.fr/oscar/),
+a recent Wikipedia dump, various [OPUS corpora](http://opus.nlpl.eu/) and a
+special corpus provided by [Kemal Oflazer](http://www.andrew.cmu.edu/user/ko/).
+
+The final training corpus has a size of 35GB and 44,04,976,662 tokens.
+
+Thanks to Google's TensorFlow Research Cloud (TFRC) we could train a cased model
+on a TPU v3-8 for 1M steps.
+
+## Model weights
+
+[Transformers](https://github.com/huggingface/transformers)
+compatible weights for both PyTorch and TensorFlow are available.

+| `dbmdz/electra-base-turkish-cased-discriminator` | [`config.json`](https://cdn.huggingface.co/dbmdz/electra-base-turkish-cased-discriminator/config.json) • [`pytorch_model.bin`](https://cdn.huggingface.co/dbmdz/electra-base-turkish-cased-discriminator/pytorch_model.bin) • [`vocab.txt`](https://cdn.huggingface.co/dbmdz/electra-base-turkish-cased-discriminator/vocab.txt)
+
+## Usage
+
+With Transformers >= 2.8 our ELECTRA base cased model can be loaded like:
+
+```python
+from transformers import AutoModelWithLMHead, AutoTokenizer
+
+tokenizer = AutoTokenizer.from_pretrained("dbmdz/electra-base-turkish-cased-discriminator")
+model = AutoModelWithLMHead.from_pretrained("dbmdz/electra-base-turkish-cased-discriminator")
+```
+

+
+All models are available on the [Huggingface model hub](https://huggingface.co/dbmdz).

+
+# Acknowledgments
+
+Thanks to [Kemal Oflazer](http://www.andrew.cmu.edu/user/ko/) for providing us
+additional large corpora for Turkish. Many thanks to Reyyan Yeniterzi for providing
+us the Turkish NER dataset for evaluation.
+
+Research supported with Cloud TPUs from Google's TensorFlow Research Cloud (TFRC).
+Thanks for providing access to the TFRC ❤️
+
+Thanks to the generous support from the [Hugging Face](https://huggingface.co/) team,
+it is possible to download both cased and uncased models from their S3 storage 🤗
