Advanced Artificial Intelligence and Computational Methods for Medical Diagnostics

Project Overview

In this project, we focused on applying advanced artificial intelligence and computational methods to solve complex problems in medical diagnostics and biomedical engineering. We utilized various machine learning models, particularly Convolutional Neural Networks (CNNs), to analyze diverse medical imagery. Our research demonstrated the use of AI for diagnosing COVID-19 from lung X-rays, segmenting brain lesions and breast tumors from MRIs and ultrasound, and diagnosing biomechanical conditions like fatigue foot. We also explored GEP for gastric cancer analysis and compared advanced models like SAM and U-Net, consistently aiming to improve diagnostic accuracy through computational intelligence.

Research Timeline & Achievements (2020–2025)

Across several studies (2020–2025), we applied data‑driven techniques to medical diagnosis. We used gene‑expression programming and sensitivity analysis to model how factors such as age, sex and H. pylori infection affect gastric cancer tumour location and size. During the COVID‑19 pandemic we developed CNNs to classify lung X‑ray images, achieving 93.2% accuracy, 96.1% sensitivity and segmenting infected tissue with 83.8% accuracy. Other projects introduced a quantum‑matched‑filter deep spiking neural network for MRI tumour segmentation, diagnosed foot fatigue using CNNs, combined robust PCA and CNNs to localise brain lesions, and compared U‑Net and Segment Anything models for breast tumour delineation.
