The number of base estimators in the ensemble
WebThe number of base estimators in the ensemble. max_samples“auto”, int or float, default=”auto” The number of samples to draw from X to train each base estimator. If int, then draw max_samples samples. If float, then draw max_samples * X.shape [0] samples. If “auto”, then max_samples=min (256, n_samples). WebTo address this challenge, we combined the Deep Ensemble Model (DEM) and tree-structured Parzen Estimator (TPE) and proposed an adaptive deep ensemble learning method (TPE-DEM) for dynamic evolving diagnostic task scenarios. ...
