The model has optimal hyperparameters, such as a learning rate of 0.002, batch size of 40, and transformer depth of 12, which were determined by, ablation studies, and sensitivity analysis. The proposed hybrid model outperforms other conventional methods with a 99.1% accuracy. Our findings prove the efficiency of hybrid architectures in breast cancer diagnosis with improved specificity and sensitivity.

The paper's core innovation lies in its hybrid ViT-CNN architecture, combining the strengths of Vision Transformers (ViT) for global context capture and Convolutional Neural Networks (CNN) for local feature extraction. This synergistic approach addresses the limitations of individual models, enabling a more comprehensive understanding of complex medical images.
ViTs excel at long-range dependencies and global contextual features, crucial for identifying subtle, dispersed patterns in cancer. CNNs, on the other hand, are highly effective at detecting localized patterns and textures. The fusion ensures that both macro and micro details contributing to a diagnosis are captured and leveraged.
This architectural choice represents a significant step forward from traditional deep learning models, offering enhanced robustness and a richer feature representation for improved diagnostic accuracy in breast cancer detection.
The research specifically targets breast cancer detection using CT and MRI modalities. These imaging techniques are vital for identifying deformities, but current manual interpretations suffer from subjectivity and human error. The proposed AI model aims to automate and standardize this process.
Advanced preprocessing techniques, including normalization, median filtering for noise reduction, and extensive image augmentation (rotation, flipping, scaling), are applied to enhance data quality and prevent overfitting, which is critical for medical datasets.
The model's high accuracy, sensitivity, and specificity (99.1%, 98.7%, 99.3% respectively) demonstrate its potential to significantly improve early diagnosis, thereby impacting patient outcomes and survival rates positively.
A key element of the model is its multi-feature fusion strategy, combining information from CT and MRI images. This multimodal approach provides a more complete picture, as different imaging modalities highlight distinct aspects of tissue structure.
The use of a Gauss-log ratio operator for image fusion is highlighted, designed to enhance tumor area visibility. This, coupled with the extraction of edge, texture, and intensity features at each pixel via a multi-feature block approach, enriches the input representation.
The mathematical model represents this fusion as a weighted sum of ViT and CNN feature vectors, optimized during training, ensuring that the most relevant information from both architectures and modalities contributes optimally to the final prediction.
The paper emphasizes rigorous tuning of hyperparameters to achieve superior performance. Optimal settings include a learning rate of 0.002, a batch size of 40, and a transformer depth of 12.
These optimal values were determined through comprehensive ablation studies and sensitivity analysis, which systematically evaluated the impact of each hyperparameter on the model's performance metrics.
The detailed analysis of hyperparameters ensures the model's robustness and efficiency, preventing issues like underfitting or overfitting and guaranteeing that the architecture is configured for peak diagnostic capability.
