Ensemble learning combines several models into one predictive model to decrease the variance and improve results. The ensemble method is divided into two groups - the sequential method and the parallel method.

Parallel method - base learners are generated parallelly

Ensembles techniques are -

  • Bagging
  • Stacking
  • Boosting
