What is Ensemble technique ? As discussed in previous few posts about predictive analytics challenges, Ensemble technique is a solution for most of them. Incremental learning environment, specifically demands for ensemble based algorithms for problem solving due to dynamic data generation functions. Ensemble technique is a class of meta-algorithms that merge various machine learning algorithms into single predictive model in order to reduce variance (bagging), bias (boosting), or increase predictions quality. Let us see a real world example to understand what ensemble technique exactly does….
