Overlooking Extra Costs
Not to mention misclassification costs that will incur. Consequently, with certain classes, the cost of one class being wrong will be greater than when another class is wrong. Slightly adjust the classifiers costs to make decision trees consistent with the special characteristics of the problem.
- Example: In a medical diagnosis decision tree, misclassifying a severe condition as non-severe may lead to costly medical interventions or delayed treatment.
- Prevention: Adjust classifier costs to reflect the importance of different types of errors, ensuring the model considers the potential costs of misclassifications.
How to Avoid Common Mistakes in Decision Trees
Decision trees are powerful tools in machine learning, but they can easily fall prey to common mistakes that can undermine their effectiveness. In this article, we will discuss 10 common mistakes in Decision Tree Modeling and provide practical tips for avoiding them.
