Machine learning methods have shown large potential for the automatic early diagnosis of Alzheimer’s Disease (AD) . However, some machine learning methods based on imaging data have poor interpretability because it is usually unclear how they make their decisions.  \nExplainable Boosting Machines (EBMs) are interpretable machine learning models based on the statistical framework of generalized additive modeling, but have so far only been used for tabular data. Therefore, we propose a framework that combines the strength of EBM with highdimensional imaging data using deep learning-based feature extraction.  \nThe proposed framework is interpretable because it provides the importance of each feature. We validated the proposed framework on the Alzheimer’s Disease Neuroimaging Initiative (ADNI) dataset, achieving accuracy of 0.883 and area-under-the-curve (AUC) of 0.970 on AD and control classification. Furthermore, we validated the proposed framework on an external testing set, achieving accuracy of 0.778 and AUC of 0.887 on AD and subjective cognitive decline (SCD) classification. The proposed framework significantly outperformed an EBM model using vol-  \n⋆ [w.kang@erasmusmc.nl](w.kang@erasmusmc.nl)  \n2 W.

However, early and accurate diagnosis of AD (Alzheimer’s Disease) is challenging [24] . Machine learning methods have shown large potential for early detection and prediction of AD because they can learn subtle patterns and capture slight tissue alterations in highdimensional imaging data [7,25] . Nevertheless, those machine learning methods with high diagnostic performance, such as deep learning, are considered black boxes because of the poor interpretability of the predicted results [3] . On the other hand, intrinsically interpretable methods can provide explainable results but often have worse predictive performance as they cannot fully exploit the high-dimensional data [2] . To this end, to facilitate the translation of machine learning to clinical practice it is crucial to find an optimal tradeoff between the accuracy and
