Advanced Genetics
Artificial intelligence (AI) has advanced predictive modeling in medicine, yet many models remain disease-specific and difficult to generalize across clinical settings. Key challenges include the trade-off between interpretability and accuracy, reliance on single algorithms, limited external validation, and biased feature importance estimation. In this Perspective, we discuss how methodological advances in computational sciences, including automated machine learning (AutoML) and neural architecture search (NAS), reveal a gap between automated hybrid systems and current clinical modeling practices. To address these challenges, we outline a principled artificial intelligence hybrid ensemble framework based on three design principles: integration of diverse learners, consensus-driven validation across independent cohorts, and transparent feature attribution using Shapley Additive exPlanations (SHAP). This framework emphasizes methodological robustness, interpretability, and cross-disease applicability to support the translation of artificial intelligence models into clinical practice.

From Disease-Specific Models to Broad Clinical Utility: A Perspective on AI Hybrid Ensemble Frameworks
This methodological Perspective argues for context-sensitive learner integration, evaluation across independent cohorts and cautious interpretation of feature attribution. Its deployment discussion identifies requirements for future clinical translation rather than reporting a newly validated model.
No new empirical evaluation is reported in this article. Application examples are cited prior studies, not new participant cohorts; their sample sizes are not pooled into a synthetic total.
Which methodological principles should guide the design, evaluation and interpretation of clinical AI ensembles?
The Perspective connects clinical AI design to the practical demands of evaluating and interpreting ensemble models. It advocates combining complementary learners according to the clinical setting and selecting models through aggregate evaluation across independent cohorts. Its discussion of SHAP emphasizes that feature attributions depend on data distributions and should be considered alongside sensitivity analysis and calibration. Distribution shift, computational resources, standardization and clinical workflow integration frame the translation agenda. On this evidence page, these arguments support methodological choices and limitations discussions; performance estimates and empirical validation claims belong to the cited primary studies, not to this Perspective.
The authors frame learner combination as a methodological design choice for clinical AI.
