Self-adaptive data-driven evolutionary algorithm based on random forest feature selection and incremental Gaussian process regression on personalized antidepressant medication research
摘要
Given the challenges of personalized depression treatment, such as individual differences, diverse medications, long treatment cycles, and adverse interactions. We proposed a self-adaptive data-driven evolutionary algorithm based on random forest feature selection and incremental Gaussian process regression (SADDEA-RFFS-IGPR). The algorithm integrates feature selection, surrogate modeling, and adaptive adjustment. We evaluated SADDEA-RFFS-IGPR on samples from three depression subtypes through model benchmark testing, comparison with same type algorithms, and ablation experiments. Results showed it achieved the best surrogate performance, an average ranking below 1.1 and statistically significant improvements (p-value < 0.05). Performance declined when any component was removed. In addition, analysis of variance (ANOVA) identified key factors. These findings confirmed the algorithm’s effectiveness, and potential in optimizing personalized treatment strategies.
