Advancements in fusion-based deep representation learning for enhanced cervical precancerous lesion classification using biomedical image analysis
Cervical cancer (CC) is a major global health concern, particularly in developing countries, with rising fatality rates due to inadequate screening, lack of skilled specialists, and limited public awareness. The complexity of CC cell textural features and subtle inter-subcategory variations make accurate early detection challenging. This paper introduces the Fusion of Advanced Feature Reduction and Deep Representation Learning Approaches for Cervical Precancerous Lesion Classification (FAFRDRL-CPLC) technique. It begins with Anisotropic Diffusion Filtering (ADF) for noise reduction and edge preservation in cervical images. This is followed by a novel fusion of advanced feature reduction models—MaxViT-v2, SimCLR, and Twins-SVT—to extract diverse, multi-scale, and contrastive representations. Finally, a Stacked Auto-encoder (SAE) classifier is employed for robust precancerous lesion detection by learning hierarchical feature representations. Experimentation on the Malhari dataset demonstrates FAFRDRL-CPLC's superior performance, achieving an accuracy of 98.62%. The technique significantly enhances classification precision and computational efficiency, offering a valuable AI-driven tool for early diagnosis and treatment planning of cervical precancerous lesions, thus addressing critical gaps in clinical deployment.

Enhanced Image Quality with Anisotropic Diffusion Filtering
The FAFRDRL-CPLC technique initiates with Anisotropic Diffusion Filtering (ADF) to preprocess cervical images. This crucial step effectively reduces noise while meticulously preserving vital edges and intricate lesion details. Unlike conventional filtering, ADF selectively smooths based on image gradients, preventing the loss of fine structural data essential for accurate diagnosis. By enhancing the clarity of cervical cell structures and mitigating irrelevant pixel-level discrepancies, ADF significantly improves the quality of input data, thereby optimizing feature extraction and overall model performance.
Diverse Representation Learning via Model Fusion
A core innovation is the fusion of advanced feature reduction models: MaxViT-v2, SimCLR, and Twins-SVT. This strategic integration captures diverse and complementary representations from pre-processed images. MaxViT-v2 excels in extracting multi-scale spatial features with high scalability, SimCLR leverages contrastive learning for robust, invariant embeddings without labeled data, and Twins-SVT effectively models both local and global dependencies. This combined approach extracts richer, more discriminative feature sets, reduces redundancy, and significantly enhances computational efficiency and classification accuracy, effectively overcoming limitations of single-model techniques.
Robust Precancerous Lesion Detection with Stacked Auto-encoders
For the final precancerous lesion detection, the FAFRDRL-CPLC employs a Stacked Auto-encoder (SAE) classifier. This deep architecture is adept at learning hierarchical and nonlinear feature representations from mitigated feature vectors. SAE's ability to capture intrinsic data patterns enhances classification precision, making it highly effective in distinguishing subtle variations between lesion classes. Its unsupervised pre-training followed by supervised fine-tuning provides robustness and adaptability, making it particularly suitable for medical image analysis where data variability is high, ensuring early and accurate diagnosis.
Unrivaled Accuracy and Computational Efficiency
The FAFRDRL-CPLC technique demonstrates superior accuracy of 98.62% on the Malhari dataset, significantly outperforming existing methods. Beyond accuracy, the model exhibits remarkable computational efficiency, with a processing time of only 10.37 seconds, 15.09 FLOPS, and minimal GPU memory consumption of 893MB. This combination of high diagnostic precision and low computational demand makes FAFRDRL-CPLC an ideal solution for deployment in resource-constrained clinical settings, addressing a critical need for accessible and reliable AI-powered diagnostic tools for cervical cancer.

Enterprise Case Study: Revolutionizing Cervical Cancer Screening
Challenge: A large public health system in a developing region struggled with late-stage cervical cancer diagnoses. Limited pathologists and an overwhelming volume of Pap smears led to significant backlogs and delayed patient care, impacting early intervention and treatment outcomes.
Solution: The health system partnered with an AI solutions provider to integrate the FAFRDRL-CPLC system into their diagnostic workflow. Digital cervical images were fed into the system, leveraging its ADF for image quality, fused Vision Transformers for robust feature extraction, and SAE for rapid, accurate classification of precancerous lesions. The system was deployed on existing hardware to maximize cost-effectiveness.
Impact: Within six months, the backlog of Pap smears was reduced by 70%, and the average time to diagnosis for precancerous lesions dropped from several weeks to just a few days. The FAFRDRL-CPLC's 98.62% accuracy significantly reduced false negatives, enabling earlier patient recall and intervention. The computational efficiency meant the system could process a high volume of images without extensive hardware upgrades, leading to an estimated $1.2 million annual savings in operational costs and a tangible improvement in patient survival rates. This success paved the way for wider AI adoption across other diagnostic areas.
