Robustness of Nomogram Versus Deep Learning Models for Hepatocarcinoma Grading: Insights From a Bilateral Cross-Center Validation.
Simple statistical models for liver cancer grading prove more reliable across different hospitals than complex AI systems that lose accuracy outside their training data.
This diagnostic or model validation study examined Robustness of Nomogram Versus Deep Learning Models for Hepatocarcinoma Grading: Insights From a Bilateral Cross-Center Validation. The PubMed abstract reports that In contrast, DL models showed high internal performance (AUCs: 0;632-0;809 for Center 1; 0;692-0;767 for Center 2) but experienced significant degradation on external validation (AUCs: 0;599-0;646 and 0;620-0;657, respectively).
