Figure 5. Visualization of random forest classifier model with the model’s features and weights. The cell color spectrum, from orange to blue, represents the confidence that a decedent’s radial artery is greater than 2.5mm (more orange) or less than 2.5mm (more blue). The Gini index can be seen decreasing further along the forest, thus indicating less variance and improved classification. Conclusively, the plot yields a decision tree for evaluating if the decedent’s radial artery is greater than or less than 2.5mm. These data also contained the associated biographic and demographic features (height(cm), carcinogen exposure, smoking history, biological sex, weight(kg), age(years), alcohol use history, and recreation drug use/substance use exposure). When the node’s statement is true, one moves to the left to the next node, and false to the right : Transradial Access - A Predictive Model to Assess Radial Artery Diameter : Science and Education Publishing
