The AdaBoost algorithm is a crucial feature classification method in machine learning, commonly employed for feature selection and feature weighting tasks. In facial expression recognition systems, AdaBoost is frequently utilized to filter multi-scale, multi-orientation high-dimensional Gabor filter response images, implementing an iterative weight adjustment approach that sequentially enhances weak classifiers into a strong ensemble classifier.
