A fine-tuned regression model that assigns a functioning level to Dutch sentences describing eating functions. The model is based on a pre-trained Dutch medical language model (link to be added): a RoBERTa model, trained from scratch on clinical notes of the Amsterdam UMC. To detect sentences about eating functions in clinical text in Dutch, use the icf-domains classification model.
|4||Can eat independently (in culturally acceptable ways), good intake, eats according to her/his needs.|
|3||Can eat independently but with adjustments, and/or somewhat reduced intake (>75% of her/his needs), and/or good intake can be achieved with proper advice.|
|2||Reduced intake, and/or stimulus / feeding modules / nutrition drinks are needed (but not tube feeding / TPN).|
|1||Intake is severely reduced (<50% of her/his needs), and/or tube feeding / TPN is needed.|
|0||Cannot eat, and/or fully dependent on tube feeding / TPN.|
The predictions generated by the model might sometimes be outside of the scale (e.g. 4.2); this is normal in a regression model.
- The model was fine-tuned (trained, validated and tested) on medical records from the Amsterdam UMC (the two academic medical centers of Amsterdam). It might perform differently on text from a different hospital or text from non-hospital sources (e.g. GP records).
- The model was fine-tuned with the Simple Transformers library. This library is based on Transformers but the model cannot be used directly with Transformers
pipelineand classes; doing so would generate incorrect outputs. For this reason, the API on this page is disabled.
To generate predictions with the model, use the Simple Transformers library:
from simpletransformers.classification import ClassificationModel model = ClassificationModel( 'roberta', 'CLTL/icf-levels-etn', use_cuda=False, ) example = 'Sondevoeding is geïndiceerd' _, raw_outputs = model.predict([example]) predictions = np.squeeze(raw_outputs)
The prediction on the example is:
The raw outputs look like this:
- The training data consists of clinical notes from medical records (in Dutch) of the Amsterdam UMC. Due to privacy constraints, the data cannot be released.
- The annotation guidelines used for the project can be found here.
The default training parameters of Simple Transformers were used, including:
- Optimizer: AdamW
- Learning rate: 4e-5
- Num train epochs: 1
- Train batch size: 8
The evaluation is done on a sentence-level (the classification unit) and on a note-level (the aggregated unit which is meaningful for the healthcare professionals).
