# 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

This model was pre-trained with ELECTRA implementation of BERT that omit Next Sentence Prediction and introduce Dynamic Masking Loss Function instead of ELECTRA function. Since the model uses ELECTRA implementation of BERT, the architecture of the model in huggingface library is indeed ELECTRA. This model was pre-trained on TPUv3-512 for 690K steps with batch size of 4,192 on both PubMed Abstracts and PMC full article + general domain vocab (EN Wiki + Books). This design choice help this model achieving State-of-the-art on certain Bio Text Classification Tasks such as ChemProt.
. In order to help researchers with limited resources to fine-tune larger models, we created an example with PyTorch XLA. PyTorch XLA (https://github.com/pytorch/xla) is a library that allows you to use PyTorch on TPU units, which is provided for free by Google Colab and Kaggle. Follow this example to work with PyTorch/XLA [Link](https://github.com/salrowili/BioM-Transformers/blob/main/examples/Fine_Tuning_Biomedical_Models_on_Text_Classification_Task_With_HuggingFace_Transformers_and_PyTorch_XLA.ipynb). In this example we achieve 80.74 micro F1 score on ChemProt task with BioM-ALBERTxxlarge . Fine-tuning takes 43 minutes for 5 epochs .

Check our GitHub repo at https://github.com/salrowili/BioM-Transformers for TensorFlow and GluonNLP checkpoints. We also updated this repo with a couple of examples on how to fine-tune LMs on text classification and questions answering tasks such as ChemProt, SQuAD, and BioASQ.
