Description
The Fraitly classifier employs MedicalBertForSequenceClassification embeddings within a robust classifier architecture. Trained on a diverse dataset, this model provides accurate label assignments and confidence scores for its predictions. The primary goal of this model is to categorize text into two key labels: Frailty_Vulnerability and No_Or_Unknown.
-
Frailty_Vulnerability: This category includes statements that highlight concerns, signs or symptoms associated with frailty and/or vulnerability conditions. -
No_Or_Unknown: This category encompasses statements that either do not present any identifiable concerns related to frailty/vulnerability or where the presence or extent of frailty/ vulnerability is indeterminate.
Predicted Entities
Frailty_Vulnerability, No_Or_Unknown
