scripts default iconClassic AdaBoost Classifier (Scripts) Publisher's description

This a classic AdaBoost implementation

This a classic AdaBoost implementation, in one single file with easy understandable code.

The function consist of two parts a simple weak classifier and a boosting part:
The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes -1 and 1
The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier"
Training mode:
Apply mode:

datafeatures : An Array with size number_samples x number_features
dataclass : An array with the class off all examples, the class
can be -1 or 1
itt : The number of training iterations
model : A struct with the cascade of weak-classifiers
estimateclass : The by the adaboost model classified data
