Impact
Our novel Cross-Non-Decimated Wavelet Transform (CNDWT) and Bayesian Optimized Multiple Linear Regression (BOMLR) algorithm offers unparalleled accuracy in early PD detection. This approach processes amplitude-sliced, augmented voice data with Haar and Daubechies wavelet transformations, identifying highly influential attributes for precise prediction. The CNDWT ensures shift-invariance and enhanced resolution, crucial for subtle vocal pattern analysis.
Achieving 99% accuracy, the CNDWT-BOMLR method significantly outperforms traditional algorithms. Key metrics like MCC, ROC, MAE, and RMSE consistently demonstrate superior predictive power and robustness across various datasets. The use of amplitude slicing augmentation effectively addresses data imbalance, leading to a more reliable and generalized model performance.
The early detection capabilities of our model allow for timely medical intervention, drastically improving patient outcomes and quality of life. By providing a non-invasive, cost-effective, and highly accurate screening tool, this research has profound implications for global healthcare, especially in underserved areas. It facilitates proactive disease management and reduces the burden on healthcare systems.

Achieved Prediction Accuracy
0 of Parkinson's Disease Cases Correctly IdentifiedThe proposed CNDWT-BOMLR model demonstrates exceptional accuracy in identifying Parkinson's disease at early stages, outperforming traditional methods.
| Aspect | Traditional DWT | Proposed CNDWT |
|---|---|---|
| Time-Frequency Resolution | Fixed resolution; loses phase info due to decimation. | Higher resolution with non-decimated sub bands; retains phase info for vocal nuances. |
| Shift Invariance | Sensitive to signal shifts (decimation causes aliasing). | Shift-invariant (no decimation), better for vocal variability. |
| Noise Robustness | Vulnerable to high-frequency noise in detail coefficients. | Reduced noise sensitivity through complex magnitude averaging. |
| PD Detection Impact | Less sensitive to vocal impairments, reduced classification performance. | More sensitive to vocal features typical in PD (e.g., jitter, shimmer), boosting classification. |
Real-World Impact: Early PD Detection
Our model's ability to leverage subtle vocal impairments for early detection means patients can receive timely intervention, significantly improving quality of life and slowing disease progression. This is particularly crucial in regions with limited access to specialized neurological care.
- Improved patient outcomes through earlier treatment.
- Reduced healthcare burden by preventing late-stage complications.
- Scalable and non-invasive screening adaptable for telemedicine.
- Enhanced diagnostic accuracy, minimizing false negatives.
The CNDWT-BOMLR framework sets a new standard for accessible and effective Parkinson's disease diagnosis, making a tangible difference in global health.
