Line 1: This algorithm is called Greedy-Iterative-Activity-Selector, because it is first of all a greedy algorithm, and then it is iterative. There's also a recursive version of ... WebJul 21, 2024 · "Greedy selection" isn't hard to understand as I'm assuming that it's talking about simply selecting the most probably token according to an argmax function, but how is this different from sampling according to a distribution? If we have a distribution, then I'm also assuming that we have the distribution function and that we're sampling ...

WebTransformer that performs Sequential Feature Selection. This Sequential Feature Selector adds (forward selection) or removes (backward selection) features to form a feature subset in a greedy fashion. At each stage, this estimator chooses the best feature to add or remove based on the cross-validation score of an estimator.
