WebAug 29, 2024 · For linear models (such as linear regression, logistic regression, etc), feature engineering is an important step to improve the performance of the models. My question is does it matter if we do any feature engineering while using random forest or … WebMar 13, 2024 · One scenario where engineered explanations might be useful is when examining the impact of individual categories from a categorical feature. If a one-hot encoding is applied to a categorical feature, then the resulting engineered explanations will include a different importance value per category, one per one-hot engineered feature.
