Classifier chains are an effective technique for modeling label dependencies in multi-label classification. However, the method requires a fixed, static order of the labels. While in theory, any order is sufficient, in practice, this order has a substantial impact on the quality of the final prediction. Dynamic classifier chains denote the idea that for each instance to classify, the …

A better solution is to exchange the static classifier for a dynamic (or "rotary") type And the latest generation of dynamic classifiers is indeed proving to be a good way of improving the fineness of the ground coal leaving the mill, with the potential to eliminate almost all the coarse fraction (>300 µm) from the supply of PF to the furnace ...

An air classifier is one of the main and effective device in cement industry. In this study, a three-dimensional, steady and two-phase (solid-gas) computational fluid dynamics (CFD) simulation was ...

Classifier chains is a key technique in multi-label classification, sinceit allows to consider label dependencies effectively. However, the classifiers arealigned according to a static order of the labels. In the concept of dynamic classifier chains (DCC) the label ordering is chosen for each ...
