Background

Skin cancer is a major cause of mortality, and early detection is vital for effective treatment. Diagnosis is challenging because of lesion variability. This study adapts VINCE‐NET, a hybrid deep‐learning model originally designed for stroke detection, to classify melanoma using dermoscopic images.

Methods

VINCE‐NET combines vision transformer layers for global context, convolutional neural networks for local features, and long short‐term memory for spatial sequence modeling. During preprocessing, Gaussian blur, normalization, and augmentation were applied to reduce noise and handle class imbalance. During training, the public HAM10000 dataset was used in a central processing unit‐only Google Colab environment (12.72 GB random access memory, 107.7 GB disk) with an AdamW optimizer, a batch size of 12, learning‐rate scheduling, and early stopping (patience = 50). VINCE‐NET's performance was compared with those of a convolutional neural networks, long short‐term memory, residual network with 50 layers (ResNet‐50), visual geometry group network with 16 and 19 layers (VGG‐16/19), and densely connected convolutional network with 121 and 201 layers (DenseNet‐121/201) under identical preprocessing conditions.

Results

VINCE‐NET achieved 94.1% accuracy, 95.5% precision, 90.4% recall, a 92.9% F1‐score, and an area under the receiver operating characteristic curve of 0.98 at a training time of 34,308.42 s. Benchmarks showed that VINCE‐NET outperformed baselines while being computationally efficient.

Conclusion

VINCE‐NET provides competitive performance for melanoma classification and feasibility in resource‐limited settings. Although promising, VINCE‐NET has not been clinically validated yet. Future work will address resolution, ablation studies, interpretability, and external validation.

Stroke remains a leading cause of death and disability worldwide, necessitating improved diagnostic tools for early detection and classification. Machine learning (ML) techniques have shown promise in addressing this critical healthcare challenge by enabling efficient analysis of stroke-related data. However, the lack of standardized datasets, limited real-time clinical applicability, and the complexity of model interpretability hinder broader adoption. This review critically examines 34 research articles published between 2014 and 2025, focusing on traditional ML, deep learning, transfer learning, and hybrid approaches for stroke detection and classification. Key findings highlight that Traditional ML models such as Support Vector Machines (SVM) and Random Forests (RF) have been widely used but show limitations in high-dimensional medical imaging tasks. Conversely, advanced deep learning models, such as EEG-DenseNet and ResNet50, excel in stroke segmentation and classification tasks, while hybrid methods demonstrate potential for improving accuracy through ensemble strategies. The review also underscores the challenges of dataset scarcity, ethical concerns, and integration barriers in clinical settings. Recommendations for future research include developing more representative datasets, advancing explainable AI methods, and exploring real-time implementation frameworks to bridge the gap between research and clinical practice.
