Model Details

Model Description

More information needed

  • Developed by: DMIS-lab (Data Mining and Information Systems Lab, Korea University)

  • Shared by [Optional]: DMIS-lab (Data Mining and Information Systems Lab, Korea University)

  • Model type: Question Answering

  • Language(s) (NLP): More information needed

  • License: More information needed

  • Parent Model: gpt-neo-2.7B

  • Resources for more information:


Direct Use

This model can be used for the task of question answering.

Downstream Use [Optional]

More information needed.

Out-of-Scope Use

The model should not be used to intentionally create hostile or alienating environments for people.

Bias, Risks, and Limitations

Significant research has explored bias and fairness issues with language models (see, e.g., Sheng et al. (2021) and Bender et al. (2021)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.


Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

Training Details

Training Data

The model creators note in the associated paper:

We used the BERTBASE model pre-trained on English Wikipedia and BooksCorpus for 1M steps. BioBERT v1.0 (镁 PubMed 镁 PMC) is the version of BioBERT (镁 PubMed 镁 PMC) trained for 470 K steps. When using both the PubMed and PMC corpora, we found that 200K and 270K pre-training steps were optimal for PubMed and PMC, respectively. We also used the ablated versions of BioBERT v1.0, which were pre-trained on only PubMed for 200K steps (BioBERT v1.0 (镁 PubMed)) and PMC for 270K steps (BioBERT v1.0 (镁 PMC))

Training Procedure


The model creators note in the associated paper:

We pre-trained BioBERT using Naver Smart Machine Learning (NSML) (Sung et al., 2017), which is utilized for large-scale experiments that need to be run on several GPUs

Speeds, Sizes, Times

The model creators note in the associated paper:

The maximum sequence length was fixed to 512 and the mini-batch size was set to 192, resulting in 98 304 words per iteration.
