AdaBoost for a two-group classification problem.
| Step 1: Initialize with . | | Step 2: Perform the following for . | | (1) Learn the weak classifier based on distribution . In other | | words, minimize the value for Formula (7), and find . | | (2) Use the error rate and calculate reliability as shown below. | | | | (3) Use the following formula to update distribution . | | | | is a normalization factor so that . | | | | Step 3: For the final classifier, the strong classifier is found | | by the following equation after making a weighted majority | | decision using the reliability of all the weak classifiers. | | |
