Statistical mechanics is one of the pillars of modern physics. The main principle behind the ensemble model is that a group of weak learners come together to form a strong learner, thus increasing the accuracy of the model. In statistical mechanics, the ensemble average is defined as the mean of a quantity that is a function of the microstate of a system, according to the distribution of the system on its microstates in this ensemble since the ensemble average is dependent on the ensemble chosen, its mathematical expression varies from ensemble to ensemble.
