A dynamic classifier has an inner rotating cage and outer stationary vanes. Acting in concert, they provide what is called centrifugal or impinging classification. In many cases, replacing a pulveriser's static classifier with a dynamic classifier improves the unit's grinding performance, reducing the level of unburned carbon in the coal in ...

Dynamic classifier selection is a variant of ensemble learning algorithm for classification predictive modelling. The strategy consists of fitting several machine learning models on the training dataset, then choosing the model that is expected to perform best when making a forecast, on the basis of particular details of instance to be forecasted.

What is the difference between using the "normal' Unite classifier and the dynamic classifier? Because when I performed the taxonomy training by importing sh_refs_qiime_ver7_dynamic_01.12.2017.fasta and then tested importing sh_refs_qiime_ver7_97_01.12.2017.fasta, I saw a difference in the final result.

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 …

Dynamic ensembles are divided into two categories: dynamic classifier selection (DCS) [21] and dynamic ensemble selection (DES) [35]. The first model assumes, that for each new example the single classifier with highest competence is selected and the decision of the ensemble is based on the output of this individual classifier.
