+# BioM-Transformers: Building Large Biomedical Language Models with BERT, ALBERT and ELECTRA
+
+# Abstract
+
+
+The impact of design choices on the performance
+of biomedical language models recently
+has been a subject for investigation. In
+this paper, we empirically study biomedical
+domain adaptation with large transformer models
+using different design choices. We evaluate
+the performance of our pretrained models
+against other existing biomedical language
+models in the literature. Our results show that
+we achieve state-of-the-art results on several
+biomedical domain tasks despite using similar
+or less computational cost compared to other
+models in the literature. Our findings highlight
+the significant effect of design choices on
+improving the performance of biomedical language
+models.
+
+# Model Description
+
+We fine-tuned BioM-ELECTRA-Large, which was pre-trained on PubMed Abstracts, on the SQuAD2.0 dataset. Fine-tuning the biomedical language model on the SQuAD dataset helps improve the score on the BioASQ challenge. If you plan to work with BioASQ or biomedical QA tasks, it's better to use this model over BioM-ELECTRA-Large. This model (TensorFlow version ) took the lead in the BioASQ9b-Factoid challenge (Batch 5) under the name of (UDEL-LAB2). To see the full details of BioASQ9B results, please check this link http://participants-area.bioasq.org/results/9b/phaseB/ ( you need to register). 
+
+Huggingface library doesn't implement Layer-Wise decay feature, which affects the performance on SQuAD task. The reported result of BioM-ELECTRA-SQuAD in our paper is 88.3 (F1) since we use ELECTRA open-source code with TF checkpoint, which uses Layer-Wise decay.

+```
+
+To reproduce results in Google Colab:
+- Make sure you have GPU enabled.
+- Clone and install required libraries through this code
+
+!git  clone https://github.com/huggingface/transformers
+
+!pip3 install -e transformers
+
+!pip3 install sentencepiece
+
+!pip3 install -r /content/transformers/examples/pytorch/question-answering/requirements.txt
+
+- Run this python code:
+
+```python
+python /content/transformers/examples/pytorch/question-answering/run_qa.py --model_name_or_path sultan/BioM-ELECTRA-Large-SQuAD2 \
+--do_eval \
+--version_2_with_negative \
+--per_device_eval_batch_size 8 \
+--dataset_name squad_v2 \
+--overwrite_output_dir \
+--fp16 \
+--output_dir out
+```
+
+- You don't need to download the SQuAD2 dataset. The code will download it from the HuggingFace datasets hub.
+
+- Check our GitHub repo at https://github.com/salrowili/BioM-Transformers for TensorFlow and GluonNLP checkpoints. 
+
+- We added examples to fine-tune BioM-ELECTRA-Large on SQuAD and BioASQ7B using TensorFlow and TPU here https://github.com/salrowili/BioM-Transformers/tree/main/examples .  In this example we show that we achieve 88.22 score in SQuAD2.0 since Tensor Flow code has Layer-wise decay feature.
