Bagging vs. Boosting: The Power of Ensemble Methods in Machine Learning

How to maximize predictive performance by creating a strong learner from multiple weak ones — Complex problems are rarely solved through singular thought or action. A collective weather forecast produced by a team of meteorologists, each with a different perspective, will likely result in better predictions than that produced by a single individual. …
