Five algorithms are examined - genetic algorithm, simulated annealing, tabu search and hybrid methods, combining the mentioned approaches in the form of memetic algorithms. Using compound optimization methods l
optimization, the neurons in the same layer are not connected. Neural networks with three layers have the capability to approximate any function. However, the determination of thenetwork architectureis not a trivial task, for example, the number of neurons in hidden layers and theiractivation ...
A collection of Ant Colony Optimization (ACO) algorithms for the data mining classification and regression tasks - febo/myra
可以使用Octave和matlab的函数库直接进行应用,这些软件里面的build-in libarary已经很好的实现了这些算法。 当要使用其它的语言来实现这些算法时,如c,c++,Java等,要确保你使用了good libary for implement these algorithms,因为不同的实现方法在性能上相差很大。 Example of using advanced optimizaion algorithmn in Oc...
Transductive classification directly estimates the labels of unlabeled instances without creating a model to classify new texts. Several algorithms considering texts represented in a vector space model have been developed to perform transductive classification such as Self-Training (Yarowsky,1995), Co-...
This work examines the application of machine learning (ML) algorithms to evaluate dissolved gas analysis (DGA) data to quickly identify incipient faults in oil-immersed transformers (OITs). Transformers are pivotal equipment in the transmission and distribution of electrical power. The failure of a ...

For the DNA microarray datasets, tumor classification based on gene expression profiles has drawn great attention, and gene selection plays a significant role in improving the classification performance of microarray data. In this study, an effective hyb
For reproducibility, set the AcquisitionFunctionName to "expected-improvement-plus" in a HyperparameterOptimizationOptions structure. To attempt to get a better solution, set the number of optimization steps to 100 instead of the default 30. fitcnet performs Bayesian optimization by default. To use ...
Hence, imbalanced datasets are another issue, as they can decrease the capability of learning-based algorithms in predicting driving styles, especially for multi-class classification cases. At times, a majority of the samples in a dataset are labelled as a single class, leaving the other classes ...
