Lecturer Yishay Mansour Itay Dangoor Overview Introduction to weak classifiers Boosting the confidence Equivalence of weak amp strong learning Boosting the accuracy recursive construction . Ata . Kaban. Motivation & beginnings. Suppose we have a learning algorithm that is guaranteed with high probability to be slightly better than random guessing – we call this a . weak learner. E.g. if an email contains the work “money” then classify it as spam, otherwise as non-spam. 0 500 1000 1500 2000 2500 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 Boosting Sparse-RF Kernel 0 0.5 1 1.5 2 2.5x 104 0 0.05 0.1 0.15 0.2 0.25 timeobjectiveIJCNN-Objective Boosting Sparse-RF Kernel 0 5000 1000 What does Leadership Theory tell us ?.
