Nearest Shrunken Centroid as Feature Selection of Microarray Data
The nearest shrunken centroid classifier uses shrunken centroids as prototypes for each class and test samples are classified to belong to the class whose shrunken centroid is nearest to it. In our study, the nearest shrunken centroid classifier was used simply to select important genes prior to classification. Random Forest, a decision tree based classification algorithm, is chosen as a classi...
متن کاملNovel Clonal Selection Algorithm Improving Selection Operator
To optimize the search of the clonal selection algorithm for the optimal solution, the selection operator is improved and a novel clonal selection algorithm is designed. The selection operator is compared with such selection operators as Roulette Wheel Selection operator, Tournament Selection operator, and Sampling Selection operator. The selection operator is improved to increase the accuracy ...
متن کاملHierarchical Classification using Shrunken Centroids
There are various types of classifiers that can be trained on gene expression data with class labels. Many of them have an embedded mechanism for feature selection, by which they distinguish a subset of significant genes that are used for future prediction. When dealing with more than two class labels, especially when the number goes up to a dozen or more, people find it useful to know the rela...
متن کاملAdaptive Operator Selection for Optimization
Evolutionary Algorithms (EAs) are stochastic optimization algorithms which have already shown their efficiency on many application domains. This is achieved mainly due to the many parameters that can be defined by the user according to the problem at hand. However, the performance of EAs is very sensitive to the setting of these parameters, and there are no general guidelines for an efficient s...
متن کاملOperator Analysis of Neutrinoless Double Beta Decay
We study the effective operators of the standard model fields which would yield an observable rate of neutrinoless double beta decay. We particularly focus on the possibility that neutrinoless double beta decay is dominantly induced by lepton-number-violating higher dimensional operators other than the Majorana neutrino mass. Our analysis can be applied to models in which neutrinoless double be...
