Background: A timely diagnosis of Alzheimer’s disease (AD) is crucial to obtain more practical treatments.
In this article, a novel approach using Auto-Encoder Neural Networks (AENN) for early detection of AD
was proposed. Method: The proposed method mainly deals with the classification of multimodal data and
the imputation of missing data. The data under study involve the MiniMental State Examination, magnetic
resonance imaging, positron emission tomography, cerebrospinal fluid data, and personal information.
Natural logarithm was used for normalizing the data. The Auto-Encoder Neural Networks was used for
imputing missing data. Principal component analysis algorithm was used for reducing dimensionality of
data. Support Vector Machine (SVM) was used as classifier. The proposed method was evaluated using
Alzheimer’s Disease Neuroimaging Initiative (ADNI) database. Then, ۱۰fold crossvalidation was used
to audit the detection accuracy of the method. Results: The effectiveness of the proposed approach was
studied under several scenarios considering ۷۰۵ cases of ADNI database. In three binary classification
problems, that is AD vs. normal controls (NCs), mild cognitive impairment (MCI) vs. NC, and MCI vs.
AD, we obtained the accuracies of ۹۵.۵۷%, ۸۳.۰۱%, and ۷۸.۶۷%, respectively. Conclusion: Experimental
results revealed that the proposed method significantly outperformed most of the stateoftheart methods.
