D3mciAD: Data-Driven Diagnosis of Mild Cognitive Impairment Utilizing Syntactic Images Generation and Neural Nets

Abstract

Alzheimer's disease, an incurable chronic neurological disorder (NLD) that affects human memory and demises cognitive thinking ability with shrinkage of the brain area. Early detection of Alzheimer's disease (AD) is the only hope to delay its effect. This study designed a computer-aided automated detection method that can detect mild cognitive impairment for AD from magnetic resonance image scans. The datadriven solution approach requires an extensive quantity of annotated images for diagnosis. However, obtaining a large amount of annotated data for medical application is a challenging task. We have exploited a deep convolutional generative adversarial network (DCGAN) for synthesizing high-quality images to increase dataset size. A fine-tuned CNN (VGG16 architecture) model works on images to extract the intuitive features for early diagnosis. The extracted features of images by VGG16 feed into the support vector machine for classification. This research has conducted copious experiments to validate the proposed method outperformed relative baselines on public datasets.

An Attention-Based CoT-ResNet With Channel Shuffle Mechanism for Classification of Alzheimer’s Disease Levels

“…As shown in Table 8, the two algorithms proposed in this paper have improved the classification results for different levels of Alzheimer's disease compared with the methods proposed by previous researchers (Liu and Shen, 2014;Sarraf and Tofighi, 2016;De Luna and Marcia, 2021;Hasan et al, 2021;Xu, 2021), while this paper extends the classification between the two previously studied diseases to three categories and achieves better classification results. Among them, Sarraf et al used the classical architecture LeNet-5 to classify functional MRI data of AD subjects with normal controls, and the accuracy of the tested…”

XAI-FusionNet: Diabetic foot ulcer detection based on multi-scale feature fusion with explainable artificial intelligence

“…Recently, different types of artificial intelligence (AI) techniques, like deep learning (DL) and machine learning (ML), have been used in medicine to create safe, low-cost, and automatic ways to diagnose diseases like cancer, tuberculosis, diabetic foot ulcers, brain tumors, and more [ [8] , [9] , [10] , [11] , [12] ]. In the field of medical image processing, various DL-based segmentation algorithms like thresholding, watersheds, region growth, etc.…”
