Where the base classifier first predicts whether an activity is a mototised ( driving, motor-bike ), a non-mototised ( riding, walking ). The learning phase should proceed like so: So I add a column type stating where an activity is motorised or otherwise. For a given a set of labels the Classifier Chain model (CC) learns classifiers as in the Binary Relevance method. All classifiers are linked in a chain through feature space. Given a data set where the -th instance has the form where is a subset of labels, is a set of features. The data set is transformed in data sets where instances of the -th data set has the form . If the -th label was assigned to the instance then is , otherwise it is . Thus, classifiers build a chain where e… bank best
