Skin cancer develops due to the unusual growth of skin cells. Early detection is critical for recognition multiclass pigmented lesions (PSLs). At an early stage, manual work by ophthalmologists takes time recognize PSLs. Therefore, several “computer-aided diagnosis (CAD)” systems are developed using image processing, machine learning (ML), and deep (DL) techniques. Deep-CNN models outperformed traditional ML approaches in extracting complex features from In this study, a special transfer...

Biometric authentication is a widely used method for verifying individuals’ identities using photoplethysmography (PPG) cardiac signals. The PPG signal non-invasive optical technique that measures the heart rate, which can vary from person to person. However, these signals also be changed due factors like stress, physical activity, illness, or medication. Ensuring system accurately identify and authenticate user despite variations significant challenge. To address issues, were preprocessed...
Cardiovascular disorders are often diagnosed using an electrocardiogram (ECG). It is a painless method that mimics the cyclical contraction and relaxation of heart’s muscles. By monitoring electrical activity, ECG can be used to identify irregular heartbeats, heart attacks, cardiac illnesses, or enlarged hearts. Numerous studies analyses signals problems have been conducted during past few years. Although heartbeat classification methods presented in literature, especially for unbalanced...
