Research on a dynamic full Bayesian classifier for time

2021年5月16日 The dynamic full Bayesian classifier is optimized by splitting the smooth parameters into intervals, optimizing the parameters by constructing a smoothing parameter configuration tree (or forest), then selecting and averaging the classifiers. The dynamic

A drift detection method based on dynamic classifier

2019年10月11日 Gama and Castillo ( 2004) claim that a significant classification error rate increase suggests a drift in the class distribution. In order to detect this type of drift, our method is inspired by drift detectors based on error monitoring such as the Drift

Dynamic classifier selection Information Fusion ACM

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 stone provides a review of the DS techniques proposed in the literature from a theoretical and

Dynamic classifier selection: Recent advances and

2018年5月1日 In this , we present an updated taxonomy of dynamic classifier and ensemble selection techniques, taking into account the following three aspects: (1) The selection approach, which considers, whether a single classifier is selected (this is known as Dynamic Classifier Selection (DCS)) or an ensemble is selected (this for its part is known

[1809.01628] Online local pool generation for dynamic

2018年9月6日 Dynamic Classifier Selection (DCS) techniques have difficulty in selecting the most competent classifier in a pool, even when its presence is assured. Since the DCS techniques rely only on local data to estimate a classifier's competence, the manner in which the pool is generated could affect the choice of the best classifier for a given sample.

A drift detection method based on dynamic classifier

2019年10月11日 The new unknown incoming examples that fall outside this global decision boundary are assumed as drifts or novelties; (2) DbDDM compares a dissimilarity prediction to a classifier prediction (assumed as true label) to monitor the pseudo prequential error to detect drifts by statistical tests.

Adapting dynamic classifier selection for concept drift

2018年8月15日 Our experimental results show that DCS is capable of adapting to different concept drift scenarios by selecting the most promising classifier/ensemble for each test instance, regardless of the concept used to train the selected classifiers. In addition, we show that the DCS performs well in most cases, and requires almost no parameter tuning.

From dynamic classifier selection to dynamic ensemble

2008年5月1日 We note that most dynamic classifier selection schemes use the concept of classifier accuracy on a defined neighborhood or region, such as the local accuracy A Priori or A Posteriori methods [10]. These classifier accuracies are usually calculated with the help of K -nearest neighbor classifiers (KNN), and its use is aimed at making an optimal

A Robust Dynamic Classifier Selection Approach for

2020年9月15日 Building on the theory of imprecise probabilities, we develop a novel robust dynamic classifier selection (R-DCS) model for data classification with erroneous labels. Particularly, spectral and spatial features are extracted from HSIs to construct two individual classifiers for the dynamic selection, respectively.

Dynamic selection and combination of one-class classifiers

2021年9月27日 A natural solution to tackle multi-class problems is employing multi-class classifiers. However, in specific situations, such as imbalanced data or high number of classes, it is more effective to decompose the multi-class problem into several and easier to solve problems. One-class decomposition is an alternative, where one-class classifiers
