There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly …

A cold flow model of a static classifier was developed to investigate the flow characteristics so that design optimisations can be made. Dynamic similarity was achieved by designing a 1/3 scale model with air as the continuous phase and glass cenospheres of a similar size distribution as pulverised fuel, to simulate the coal dust.

Multiple Classifier Systems (MCS) have been widely studied as an alternative for increasing accuracy in pattern recognition. One of the most promising MCS approaches is Dynamic Selection (DS), in which the base classifiers are selected on the fly, according to each new sample to be classified. This paper provides a review of the DS techniques proposed in …
Our dynamic classifier chains extension of RDT is strongly relying on this property. ... 5.3 Static vs. Dynamic Label Orderings. In this experiment we evaluated the advantage of the dynamic chain ordering in comparison to using a static chain ordering. Taking advantage of our controlled environment, we built for both approaches the same ...

Dynamic Selection (DS) refers to techniques in which the base classifiers are selected dynamically at test time, according to each new sample to be classified. Only the most competent, or an ensemble of the most competent classifiers is …
Dynamic classifier selection is a classification technique that, for every new instance to be classified, selects and uses the most competent classifier among a set of available ones. In this way, a new classifier is obtained, whose accuracy often outperforms that of...
We show how to adapt random decision trees so that static and dynamic classifier chains can be modeled in the same structure, and thus be compared to each other within an otherwise identical model. ... The previous experiments on RDT (Section 4.4) showed that this dataset is appropriate to investigate the effect of static vs. dynamic label ...
The course residue with an HEP Dynamic Classifier is substantially lower than with a static classifier as can be seen in the Particle Size Destitution curve below showing % < 200 mesh verses % > 100 Mesh as a function of rotor speed. The HEP Dynamic Classifier, as compared to a static classifier, reduces the particle
This paper proposed two concepts of classifier chains algorithms that are able to change label order of the chain without rebuilding the entire model and developed a simple heuristic that allows the system to find relatively good label order. In this paper, we deal with the task of building a dynamic ensemble of chain classifiers for multi-label classification. To do so, …

Classical supervised learning tasks deal with the problem to assign a single class label to an instance. Multi-label classification (MLC) is an extension of these problems where each instance can be associated with multiple labels from a given label space [].A straight-forward solution, referred to as binary relevance decomposition (BR), learns a separate classification …
