**TLDR:** An ensemble technique that combines the outputs of multiple base models through a higher-level meta-model.

<p>Stacking is an advanced ensemble approach that attempts to combine the strengths of different model families within one system. Predictions from base models are learned by a second-level meta-model. This can improve performance when different models exhibit different error patterns. However, the training procedure must be designed carefully to avoid data leakage.</p>
