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. Ex: i...

Interestingly, dynamic classifier selection is regarded as an alternative to EoC [10], [11], [15], and is supposed to select the best single classifier instead of the best EoC for a given test pattern. The question of whether or not to combine dynamic schemes and EoC in the selection process is a debate being carried out [14]. But, in fact, the ...

This paper describes a framework for Dynamic Classifier Selection (DCS) whose novelty resides in its use of features that address the difficulty posed by the classification problem in terms of orienting both pool generation and classifier selection. The classification difficulty is described by meta-features estimated from problem data using ...

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.

2013. In this paper we propose a new approach for dynamic selection of ensembles of classifiers. Based on the concept named multistage organizations, the main objective of which is to define a multi-layer fusion function adapted to each recognition problem, we propose dynamic multistage organization (DMO), which defines the best multistage structure for each test sample.

In this work, the dynamic nature of data imbalance in CIL is shown and a novel Dynamic Residual Classifier (DRC) is proposed to handle this challenging scenario. Specifically, DRC is built upon a recent advance residual classifier with the branch layer merging to handle the model-growing problem. Moreover, DRC is compatible with different CIL ...

Dynamic classifier selection (DCS) is a classification technique that, for each new sample to be classified, selects and uses the most competent classifier among a set of available ones. We here propose a novel DCS model (R-DCS) based on the robustness of its prediction: the extent to which the classifier can be altered without changing its prediction. In order to define and …

The Dynamic Classifier System is potentially more efficient at discovering modules because it can identify the building blocks of those modules through chaining. Measuring the utility of pieces and creating larger ones from them may be a better approach than forming en- tire solutions and then randomly decomposing them ...

Both static and dynamic schemes may be devoted to classifier selection, providing a single classifier, or to ensemble selection, selecting a subset of classifiers from the pool. Usually, the selection is done by estimating the competence of the classifiers available in the pool on local regions of the feature space.

If we plot this dataset in a 2D graph it might look something like this feature space: Through training the classifier determines the green decision boundary. When a new sample is given it will predict which class it belongs to based on the region it is in.. This green decision boundary is what is usually aimed for when designing a classification algorithm.
