Model Card for Model ID

This is a fine-tuned version of the pre-trained biomedical language model bsc-bio-ehr-es in Spanish, tailored for text classification tasks. We used two NVIDIA GPUs for training.

Model Details

Model Description

This model has been fine-tuned for text classification on dermatological Spanish electronic health records (EHR). It leverages the pre-trained biomedical language understanding from the bsc-bio-ehr-es model and adapts it to classify dermatology-related texts effectively. The model is intended to predict among 25 different skin diseases from a medical record. It could be a first visit or a follow-up visit. It takes as input four features:

• textual medical record: the EHR written by a doctor
• disease type: the type of disease associated with the EHR
• disease location: the location in the body of the disease
• disease severity: how severe or lethal is the disease

This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated.

Uses

The Model is meant to be used for research ONLY ! The industrial version of the model is called predict-dermat and is meant to predict not only the disease but also the 3 features mentionned above. We DO NOT recommend to fine-tune this model. It is already meant to be a downstream task.

Direct Use

This model can be directly used for classifying dermatological text data in Spanish EHRs.

Downstream Use

The model can be integrated into healthcare applications for automatic classification of dermatological conditions from patient records.

Out-of-Scope Use

The model is not suitable for non-medical text classification tasks or for texts in languages other than Spanish.

Bias, Risks, and Limitations

This model is fine-tuned on a specific dataset and may not generalize well to other types of medical texts or conditions. Users should be cautious of biases in the training data that could affect the model's performance.

Recommendations

Users should validate the model's performance on their specific data and consider any ethical implications of deploying a machine learning model in a healthcare setting.

How to Get Started with the Model

from transformers import RobertaTokenizerFast, RobertaForSequenceClassification,

tokenizer = RobertaTokenizerFast.from_pretrained("fundacionctic/oracle-dermat")
model = RobertaForSequenceClassification.from_pretrained("fundacionctic/oracle-dermat")


inputs = tokenizer("Ejemplo de texto dermatológico".tolist(),
            truncation=True,
            padding='max_length',
            max_length=max_length,  # Replace with your desired maximum sequence length
            return_tensors='pt',
            return_attention_mask=True,
        ))
outputs = model(input_ids, attention_mask=attention_mask)
