-# Model Description
-* A RoBERTa [[Liu et al., 2019]](https://arxiv.org/pdf/1907.11692.pdf) model fine-tuned for de-identification of medical notes.
-* Sequence Labeling (token classification): The model was trained to predict protected health information (PHI/PII) entities (spans). A list of protected health information categories is given by [HIPAA](https://www.hhs.gov/hipaa/for-professionals/privacy/laws-regulations/index.html).
-* A token can either be classified as non-PHI or as one of the 11 PHI types. Token predictions are aggregated to spans by making use of BILOU tagging.
-* The PHI labels that were used for training and other details can be found here: [Annotation Guidelines](https://github.com/obi-ml-public/ehr_deidentification/blob/master/AnnotationGuidelines.md)
-* More details on how to use this model, the format of data and other useful information is present in the GitHub repo: [Robust DeID](https://github.com/obi-ml-public/ehr_deidentification).
-# How to use
-* A demo on how the model works (using model predictions to de-identify a medical note) is on this space: [Medical-Note-Deidentification](https://huggingface.co/spaces/obi/Medical-Note-Deidentification).
-* Steps on how this model can be used to run a forward pass can be found here: [Forward Pass](https://github.com/obi-ml-public/ehr_deidentification/tree/master/steps/forward_pass)
-* In brief, the steps are:
-    * Sentencize (the model aggregates the sentences back to the note level) and tokenize the dataset.
-    * Use the predict function of this model to gather the predictions (i.e., predictions for each token).
-    * Additionally, the model predictions can be used to remove PHI from the original note/text.
-# Dataset
-* The I2B2 2014 [[Stubbs and Uzuner, 2015]](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4978170/) dataset was used to train this model.

-# Training procedure
-* Steps on how this model was trained can be found here: [Training](https://github.com/obi-ml-public/ehr_deidentification/tree/master/steps/train). The "model_name_or_path" was set to: "roberta-large".
-    * The dataset was sentencized with the en_core_sci_sm sentencizer from spacy.
-    * The dataset was then tokenized with a custom tokenizer built on top of the en_core_sci_sm tokenizer from spacy.
-    * For each sentence we added 32 tokens on the left (from previous sentences) and 32 tokens on the right (from the next sentences).
-    * The added tokens are not used for learning - i.e, the loss is not computed on these tokens - they are used as additional context.
-    * Each sequence contained a maximum of 128 tokens (including the 32 tokens added on). Longer sequences were split.
-    * The sentencized and tokenized dataset with the token level labels based on the BILOU notation was used to train the model.
-    * The model is fine-tuned from a pre-trained RoBERTa model.
-* Training details:
-    * Input sequence length: 128
-    * Batch size: 32 (16 with 2 gradient accumulation steps)
-    * Optimizer: AdamW
-    * Learning rate: 5e-5
-    * Dropout: 0.1
