WebJun 18, 2024 · · Active Learning is a methodology that can sometimes greatly reduce the amount of labeled data required to train a model. It does this by prioritizing the labeling work for the experts. Active Learning Allows to reduce cost while improving accuracy. Is an enhancement on top of your existing model. It is a strategy/algorithm, not a model. WebMar 31, 2024 · Margin sampling is an SVM-specific active learning method which exploit SVM geometrical structure. SVM aims to seek an optimal hyperplane to separate two classes, which is based on the maximum margin principle between two classes.
