WebFeb 2, 2024 · 3. Decision trees are focused on probability and data, not emotions and bias. Although it can certainly be helpful to consult with others when making an important decision, relying too much on the opinions of your colleagues, friends or family can be risky. For starters, they may not have the entire picture. WebJun 29, 2024 · The Random Forest algorithm has built-in feature importance which can be computed in two ways: Gini importance (or mean decrease impurity), which is computed from the Random Forest structure. Let’s look at how the Random Forest is constructed. It is a set of Decision Trees. Each Decision Tree is a set of internal nodes and leaves.
WebJul 4, 2024 · I wrote a function (hack) that does something similar for classification (it could be amended for regression). The essence is that you can just sort features by importance and then consult the actual data to see what the positive and negative effects are, with the reservation that decision trees are nonlinear classifiers and therefore it's difficult to …
