Ensemble learning is a technique in machine learning where multiple models, known as \textit{weak learners}, are combined to produce more accurate predictions. Mathematically, ensemble learning can be defined as combining the predictions of $M$ weak learners to form a final prediction $\hat{y}$, such that: \begin{equation}
