Classifier chain

sklearn.multioutput.ClassifierChain class sklearn.multioutput. ClassifierChain (base_estimator, *, order = None, cv = None, random_state = None) [source] . A multi-label model that arranges binary classifiers into a chain. Each model makes a prediction in the order specified by the chain using all of the available features provided to the model plus the predictions of models that are

    The OP reports that when a series of one-vs-rest classifiers are chained together in an ensemble from most accurate to least, the overall predictive accuracy of the ensemble decreases compared to the unchained version.. This makes perfect sense. Imagine a simpler case of 3 classes of data, A, B, & C that are used to build the chain you describe: AvsBC, BvAC, and CvAB

In our example we will let the first classifier in the chain have one hidden layer with 50 units, and we will set dropout to $0.1$ as an attempt to reduce overfitting. Moreover our

    Classifier chains (see ClassifierChain) are a way of combining a number of binary classifiers into a single multi-label model that is capable of exploiting correlations among targets. For a multi-label classification problem with N classes, N binary classifiers are assigned an integer between 0 and N-1

    This paper presents the double layer based classifier chains method (DCC), which overcomes dis- advantages of BR and inherits the benefit of classifier chain method (CC), and extends this approach further in an ensemble framework. In multi-label learning, each training example is associated with a set of labels and the task is to predict the proper label set for each unseen instance

    Jun 01, 2015 Jun 01, 2015 Multi-output inference tasks, such as multi-label classification, have become increasingly important in recent years. A popular method for multi-label classification is classifier chains, in which the predictions of individual classifiers are cascaded along a chain, thus taking into account inter-label dependencies and improving the overall performance
