Schizophrenia (SZ) is a severe neuropsychiatric illness that interferes with cognitive and emotional functioning, making early diagnosis essential. Traditional clinical assessments are often subjective, while EEG signals offer valuable insights but are challenged by high dimensionality, noise, and non-linear patterns. To address these issues, a Novel Heterogeneous Dual-Channel Edge-Enhanced Temporal Graph Convolutional Networks with Quantum-Based Avian Navigation Optimizer (NHDETGCNets+QBANO) is proposed for accurate schizophrenia prediction. The proposed framework begins with the preprocessing of raw EEG signals obtained from the Moscow and Warsaw schizophrenia datasets, employing the Adaptive Self-Guided Loop Filter (AS-GLF) to efficiently suppress noise, artifacts, and other signal distortions while enhancing overall signal quality. Subsequently, informative features are extracted using the Quaternion Quadratic-Phase Fourier Transform Domain (QQ-PFTD), capturing both the temporal and spectral characteristics of the EEG signals. For predictive modeling, the NHDETGCNets architecture is utilized, which seamlessly integrates A Novel Dual-Channel Temporal Convolutional Network (AND-CTCN) with a Heterogeneous Edge-Enhanced Graph Attention Network (HE-EGAN), enabling robust relational modeling across EEG channels. To further optimize performance, the Quantum-Based Avian Navigation Optimizer (QBANO) is employed for dynamic hyperparameter tuning, ensuring faster convergence, minimized error rates, reduced computational overhead, and enhanced scalability. Extensive experimental evaluations demonstrate that the NHDETGCNets+QBANO framework consistently achieves an outstanding prediction accuracy of 99.9%, outperforming existing state-of-the-art approaches and establishing itself as a highly reliable and efficient tool for the early and precise prediction of schizophrenia. The outcomes of the suggested framework provide reliable and precise schizophrenia prediction, accurately distinguishing affected individuals, reducing errors, maintaining consistent performance, and demonstrating robustness and efficiency for early detection.
