Interpretable hybrid ensemble with attention-based fusion and EAOO-GA optimization for lung cancer detection
Lung cancer's high mortality rate underscores the critical need for early and accurate diagnosis, as late-stage diagnoses often lead to 5-year survival rates as low as 5% compared to 56% for early detection, imposing significant economic burdens on healthcare systems and diminishing patient quality of life. While deep learning models offer promising tools for analyzing Computed Tomography (CT) scans, they often suffer from limitations in generalizability, interpretability, and sensitivity to imbalanced data. This paper introduces SE-FusionEAOO Ensemble, a new robust framework for lung cancer classification. Our approach leverages the strengths of multiple deep learning architectures through a sophisticated two-stage process.

The SE-FusionEAOO Ensemble Framework
Our novel hybrid framework introduces a robust two-stage process for lung cancer classification. It leverages multiple deep learning architectures through strategic feature fusion and Squeeze-and-Excitation (SE) blocks for adaptive feature recalibration. The key innovation is the deployment of the Enhanced Animated Oat Optimization algorithm with Genetic Operators (EAOO-GA) to precisely optimize ensemble weights, ensuring optimal contribution from each model and significantly reducing overfitting.
State-of-the-Art Performance & Generalization
The SE-FusionEAOO Ensemble achieved a state-of-the-art accuracy of 99.40%, with 99.2% precision, 99.5% recall, and 99.3% F1-score on the IQ-OTH/NCCD dataset. It significantly outperforms individual models, conventional ensemble methods, and other metaheuristic optimizers. Furthermore, external validation on the LIDC-IDRI dataset yielded 97.9% accuracy and 97.8% F1-score, confirming strong generalization capabilities across independent clinical domains.
Transparent Diagnostics with Grad-CAM
To foster clinical trust, our framework integrates Gradient-weighted Class Activation Mapping (Grad-CAM). This technique generates visual heatmaps that highlight the critical image regions influencing the model's predictions. For malignant cases, Grad-CAM precisely focuses on suspicious features like spiculated margins, aligning with radiological expertise and ensuring the model identifies clinically relevant biomarkers, moving beyond "black-box" decisions.

Interpretable Lung Cancer Detection with Grad-CAM
The framework integrates Gradient-weighted Class Activation Mapping (Grad-CAM) to generate visual explanations of the model's decision-making process. For malignant cases, Grad-CAM heatmaps precisely focus on morphologically suspicious features like spiculated margins and irregular nodule contours, aligning with radiological expertise. This transparency not only fosters clinical trust but also validates the model's ability to identify clinically relevant biomarkers, moving beyond "black-box" predictions.
