Clinical Relevance of XAI in Practice
A crucial aspect of our framework is its ability to provide patient-wise explanations. For instance, in one clinical case, the model predicted high Parkinson's disease likelihood (94%) due to severe motor symptoms (tremor, rigidity, increased UPDRS score of 123.51) despite relatively maintained cognitive function (MoCA=22.8). In another, even more severe impairment (MoCA=6.46, UPDRS=144.35, advanced age=87) strongly confirmed the diagnosis. This granular interpretability allows clinicians to understand why a prediction was made, fostering trust and enabling personalized treatment decisions.
Framework Methodology Overview
The proposed framework integrates state-of-the-art machine learning and Explainable AI (XAI) methods to provide a robust and interpretable solution for Parkinson's disease prediction. It begins with comprehensive data acquisition, combining neuroimaging and diverse clinical features. Following thorough preprocessing steps like normalization and encoding, a multimodal feature set is created. This data is then used to train and evaluate various ML classifiers, with AdaBoost demonstrating superior performance.
Central to our approach is the extensive use of XAI techniques—SHAP, LIME, and ELI5—which offer both local and global interpretability. These methods reveal the underlying drivers of the model's predictions, identifying key biomarkers and enhancing the clinical relevance and trustworthiness of the diagnostic process. The framework ensures a balance between predictive accuracy and transparent decision-making, crucial for practical adoption in healthcare settings.
