Fig. 4: SHAP summary plot.
From: Predicting dementia in people with Parkinson’s disease
Beeswarm plot showing the contribution of the top features to the model’s output. Each point represents a single observation, with the horizontal axis indicating the SHAP value (impact on model output). Features are ranked by mean absolute SHAP value, from most to least important. Color represents the original feature value (red = high, blue = low), illustrating how feature magnitude influences model predictions. The bottom entry aggregates the combined impact of 44 additional features not shown individually.
