+# Electra base ⚡ + SQuAD v1 ❓
+
+[Electra-base-discriminator](https://huggingface.co/google/electra-base-discriminator) fine-tuned on [SQUAD v1.1 dataset](https://rajpurkar.github.io/SQuAD-explorer/explore/1.1/dev/) for **Q&A** downstream task.
+
+## Details of the downstream task (Q&A) - Model 🧠
+
+**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](https://arxiv.org/pdf/1406.2661.pdf). At small scale, ELECTRA achieves strong results even when trained on a single GPU. At large scale, ELECTRA achieves state-of-the-art results on the [SQuAD 2.0](https://rajpurkar.github.io/SQuAD-explorer/) dataset.
+
+
+## Details of the downstream task (Q&A) - Dataset 📚
+
+**S**tanford **Q**uestion **A**nswering **D**ataset (SQuAD) is a reading comprehension dataset, consisting of questions posed by crowdworkers on a set of Wikipedia articles, where the answer to every question is a segment of text, or span, from the corresponding reading passage, or the question might be unanswerable.
+SQuAD v1.1 contains **100,000+** question-answer pairs on **500+** articles.
+
+## Model training 🏋️‍
+
+The model was trained on a Tesla P100 GPU and 25GB of RAM with the following command:
+
+```bash
+python transformers/examples/question-answering/run_squad.py \
+  --model_type electra \
+  --model_name_or_path 'google/electra-base-discriminator' \
+  --do_eval \
+  --do_train \
+  --do_lower_case \
+  --train_file '/content/dataset/train-v1.1.json' \
+  --predict_file '/content/dataset/dev-v1.1.json' \
+  --per_gpu_train_batch_size 16 \
+  --learning_rate 3e-5 \
+  --num_train_epochs 10 \
+  --max_seq_length 384 \
+  --doc_stride 128 \
+  --output_dir '/content/output' \
+  --overwrite_output_dir \
+  --save_steps 1000
+```
+
+## Test set Results 🧾
+
+| Metric | # Value   |
+| ------ | --------- |
+| **EM** | **83.03** |
+| **F1** | **90.77** |
+| **Size**| **+ 400 MB** |
+
+Very good metrics for such a "small" model!
+
+```json

+```
+
+### Model in action 🚀
+
+Fast usage with **pipelines**:
+
+```python
+from transformers import pipeline
+
+QnA_pipeline = pipeline('question-answering', model='mrm8488/electra-base-finetuned-squadv1')
+
+QnA_pipeline({
+    'context': 'A new strain of flu that has the potential to become a pandemic has been identified in China by scientists.',
+    'question': 'What has been discovered by scientists from China ?'
+})
+# Output:
+{'answer': 'A new strain of flu', 'end': 19, 'score': 0.9995211430099182, 'start': 0}
+```
