Special Issue Information

Dear Colleagues,

The development of advanced sensors optimized for translating biological and biomedical information into digital data is continually progressing, enhancing our ability to gather precise human physiology data to support diagnoses of various diseases. These devices collect information from numerous sources, including physiological signals and medical images. Critical data can be extracted to feed artificial intelligence models, including machine learning (ML) and deep learning (DP) algorithms, using advanced signal and image processing techniques to support decision-making across multiple domains.

This Special Issue is dedicated to presenting the latest discoveries, emerging concepts, and technological applications of ML and DP within the health context. We invite contributions on a wide range of topics, including but not limited to:

  • Signal Processing ML-Based Analysis: This includes the analysis of signals such as EEG (electroencephalogram), EMG (electromyogram), ECG (electrocardiogram), FNIRs (functional near-infrared spectroscopy), and evoked potentials.
  • Imaging ML-Based Analysis: Contributions can also cover the application of ML in analyzing medical imaging modalities like X-ray, PET (positron emission tomography), CT (computed tomography), MRI (magnetic resonance imaging), and SPECT (single-photon emission computed tomography).
  • Wearable Bio-Technology Applications Supported by ML: Emerging wearable technologies that leverage ML algorithms to monitor and analyze physiological data in real time are also of great interest.

Background: Alzheimer’s disease (AD) is a progressive and irreversible neurodegenerative condition that increasingly impairs cognitive functions and daily activities. Given the incurable nature of AD and its profound impact on the elderly, early diagnosis (at the mild cognitive impairment (MCI) stage) and intervention are crucial, focusing on delaying disease progression and improving patients’ quality of life. Methods: This work aimed to develop an automatic sMRI-based method to detect AD in three different stages, namely healthy controls (CN), mild cognitive impairment (MCI), and AD itself. For such a purpose, brain sMRI images from the ADNI database were pre-processed, and a set of 22 texture statistical features from the sMRI gray-level co-occurrence matrix (GLCM) were extracted from various slices within different anatomical planes. Different combinations of features and planes were used to feed classical machine learning (cML) algorithms to analyze their discrimination power between the groups. Results: The cML algorithms achieved the following classification accuracy: 85.2% for AD vs. CN, 98.5% for AD vs. MCI, 95.1% for CN vs. MCI, and 87.1% for all vs. all. Conclusions: For the pair AD vs. MCI, the proposed model outperformed state-of-the-art imaging source studies by 0.1% and non-imaging source studies by 4.6%. These results are particularly significant in the field of AD classification, opening the door to more efficient early diagnosis in real-world settings since MCI is considered a precursor to AD.
