# ScholarBERT-XL_100 Model

This is the **ScholarBERT-XL_100** variant of the ScholarBERT model family.

The model is pretrained on a large collection of scientific research articles (**221B tokens**).

This is a **cased** (case-sensitive) model. The tokenizer will not convert all inputs to lower-case by default.

The model has a total of 770M parameters.


# Model Architecture

| Hyperparameter  | Value |
|-----------------|:-------:|
| Layers     | 36    |
| Hidden Size     | 1280  |
| Attention Heads | 20    |
| Total Parameters | 770M |


# Training Dataset

The vocab and the model are pertrained on **100% of the PRD** scientific literature dataset.
 
The PRD dataset is provided by Public.Resource.Org, Inc. (“Public Resource”), 
a nonprofit organization based in California. This dataset was constructed from a corpus
of journal article files, from which We successfully extracted text from 75,496,055 articles from 178,928 journals.
The articles span across Arts & Humanities, Life Sciences & Biomedicine, Physical Sciences,
Social Sciences, and Technology. The distribution of articles is shown below.
