• Selected slices are resized to 16 by 16, vectorized into 256 features, and Z-score normalized before PCA. — A Specialized Importance-Aware Quantum Convolutional Neural Network with Ring-Topology (IA-QCNN) for MGMT Promoter Methylation Prediction in Glioblastoma
• Importance-aware weighting uses learnable Ry and Rz rotations to scale feature amplitude and phase contributions. — A Specialized Importance-Aware Quantum Convolutional Neural Network with Ring-Topology (IA-QCNN) for MGMT Promoter Methylation Prediction in Glioblastoma
• PCA reduces dimensionality while preserving 95% explained variance under an upper qubit limit. — A Specialized Importance-Aware Quantum Convolutional Neural Network with Ring-Topology (IA-QCNN) for MGMT Promoter Methylation Prediction in Glioblastoma
• PCA-reduced features are scaled to the interval from negative pi to pi for compatibility with rotation gates. — A Specialized Importance-Aware Quantum Convolutional Neural Network with Ring-Topology (IA-QCNN) for MGMT Promoter Methylation Prediction in Glioblastoma
• The quantum feature encoding maps each feature to an Ry rotation on the zero state. — A Specialized Importance-Aware Quantum Convolutional Neural Network with Ring-Topology (IA-QCNN) for MGMT Promoter Methylation Prediction in Glioblastoma
• The feature weighting mechanism is differentiable and soft rather than a hard thresholding or position-based weight-sharing method. — A Specialized Importance-Aware Quantum Convolutional Neural Network with Ring-Topology (IA-QCNN) for MGMT Promoter Methylation Prediction in Glioblastoma
