How can I visualize feature importance in my model?
You can visualize feature importance using various methods like bar plots, SHAP values, or permutation importance.
What libraries can I use for this?
Popular libraries include Matplotlib, Seaborn, and SHAP for Python. They provide great tools for visualization.
Can you give me an example of using SHAP?
Sure! First, install the SHAP library, then use the shap.TreeExplainer
for tree-based models to get feature importance.
What about using permutation importance?
Permutation importance can be calculated using the permutation_importance
function from the sklearn
library. It measures the change in model performance when the feature values are shuffled.
