Abstract

Cervical cancer continues to be a major disease in the world, especially in low-resource countries, where early and accurate diagnosis is often difficult. It has offered promising ways for automated medical image analysis in recent years; yet, issues related to extracting features for robust cervical cancer detection with LOA optimization need to be addressed. Therefore, in this study, cervical cell images were preprocessed using attention-enhanced LSTM and extracted features. The AE-LSTM component captures sequential and contextual dependency in derived features, and preprocessing to transformer-based multi-scale feature extraction on a transformer encoder with LOA optimization. Experimental evaluation on benchmark cervical cancer datasets shows a better overall performance in terms of training accuracy curve, training loss curve, confusion matrix, ROC curve, precision-recall curve, model comparison bar graph, LOA convergence Plot, and Feature Visualization (t-SNE). It developed a transformer encoder to produce either normal or abnormal diagnosis output. Future work will include domain adaptation for low-resource environments, combination with multi-modal clinical data, and the design of lightweight models suitable for the deployment of real-time cervical cancer screening systems.
