Data validation scoring
WebThe scoring system showed good discrimination with the AUROC of 0.805 and 0.772 in two validation cohorts. Conclusions: The scoring system using routine laboratory data was able to predict the development of AKI in critically ill cirrhotic patients. The utility of this score in clinical care requires further research. WebA learning curve shows the validation and training score of an estimator for varying numbers of training samples.

Training score is more than the validation score when the model overfits. Typically, the validation score is less than the training score, because model fits on training data, and validation data is unseen by the model. Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively …
