MultiLabel Classification With ScikitMultiLearn

5 hours ago Section.io Show details

Multi-Label Classification with Scikit-MultiLearn. Multi-label classification allows us to classify data sets with more than one target variable. In multi-label classification, we have several labels that are the outputs for a given prediction. When making predictions, a given input may belong to more than one label.

1. Multilabel classification format¶ In multilabel learning, the joint set of binary classification tasks is expressed with label binary indicator array: each sample is one row of a 2d array of shape (n_samples, n_classes) with binary values: the one, i.e.
2. One-Vs-The-Rest¶ This strategy, also known as one-vs-all, is implemented in OneVsRestClassifier. The strategy consists in fitting one classifier per class.
3. One-Vs-One¶ OneVsOneClassifier constructs one classifier per pair of classes. At prediction time, the class which received the most votes is selected.
4. Error-Correcting Output-Codes¶ Output-code based strategies are fairly different from one-vs-the-rest and one-vs-one. With these strategies, each class is represented in a Euclidean space, where each dimension can only be 0 or 1.
5. Multioutput regression¶ Multioutput regression support can be added to any regressor with MultiOutputRegressor. This strategy consists of fitting one regressor per target.
6. Multioutput classification¶ Multioutput classification support can be added to any classifier with MultiOutputClassifier. This strategy consists of fitting one classifier per target.
7. Classifier Chain¶ 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.

How is multi label classification different from multi class classification?

There are no constraints about the number of classes that an instance can be assigned to in a multi-label problem. In a similar context, there exists the multi-class classification problem. However, the key difference between both is the fact that multi-label classification supposes that the properties are not mutually exclusive.
