Error-Bias DecompositionIt refers to the process of decomposing the integrated generalization error, which can be expressed as follows:

$latex {E= \overline {E}- \overline {A}}$latexE=E−A

In this formula, E on the left represents the generalization error after integration, and $latex {\overline {E}}$latexE is the average generalization error of the individual learners, $latex {\overline {A}}$latexA It represents the ensemble divergence of individual learners. From this formula, we can conclude that the higher the accuracy and diversity of individual learners, the better the ensemble effect.
