AdaBoost (Adaptive Boosting) is a powerful classifier that works well on both basic and more complex recognition problems. AdaBoost works by creating a highly accurate classifier by combining many relatively weak and inaccurate classifiers. AdaBoost therefore acts as a meta algorithm, which allows you to use it as a wrapper for other classifiers. AdaBoost was first proposed to solve classification problems using decision trees but has since been applied to several different classification and regression problems using different models as the weak learners. In this paper, two existing versions of AdaBoost—AdaBoost.R2 and AdaBoost.R —are applied to a real-world problem in

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We propose to use AdaBoost to efficiently learn classifiers over very large and possibly distributed data sets that cannot fit into main memory, as well as on-line learning where new data become available periodically. We propose two new ways to apply AdaBoost. The Although AdaBoost offers a very efficient feature selection technique, the number of features selected from the over-complete haar wavelet features is often too large for a practical real-time application (see next subsection). However, the algorithm is suitable for parallel implementation using hardware and this is the motivation for our work. ≤

Boosting and AdaBoost for Machine Learning. Broad classes of statistical classification algorithms have been developed and applied successfully to a wide range of real-world domains. In general, ensuring that the particular classification algorithm matches the properties of the data is crucial in providing results that meet the needs of the particular application domain., I would love to help you understanding where Naive Bayes is used in Real Life. The following are the Use Cases of Naive Bayes: Categorizing news, email spam detection, face recognition, sentiment analysis, medical diagnosis, digit recognition and.
