The first (global) optimization stage incorporates two steps. It is commenced by constructing an initial surrogate model within domainXddetermined using the procedure explained in “Dimensionality-reduced model domain” section. Subsequently, a machine learning process is launched, by means of which the...
Dimensionality ReductionMany problem classes in machine learning are inherently high dimensional. Natural language processing problems, for instance, often involve the extraction of meaning from words, which can appear in...doi:10.1007/978-1-4842-6373-0_8Hull, Isaiah...
In contrast, if the categories are overlapping, machine learning may not be so successful. At the very least you can expect to have to work harder and be more creative to make decent predictions. This is the case below, which is the same as the previous plot except that now we are grou...

in the literature methods are compared based on this figure of merit, we believe that such comparison could be misleading here because the DR algorithms that we utilized involved transforming the original data into quantities that did not always possess an easily interpretable physical meaning. Case...
Applying PCA to your data set loses its meaning. If interpretability of the results is important for your analysis, PCA is not the right technique for your project.Components of Dimensionality Reduction Here are three main points on Dimensionality Reduction techniques:...

Machine learning applications for multi-source data of edible crops: A review of current trends and future prospects YanyingZhang,YuanzhongWang, inFood Chemistry: X, 2023 3.1.2Dimensionality reduction Because of the characteristics of high-dimensional data, it is difficult to understand and analyze...
The algorithm control parameters are gathered in Table 3, their meaning has been already elaborated on earlier. Here we provide general guidelines for their setup. Four parameters of Table 3, i.e., N1 through N4, pertain to the computational budget of the entire optimization framework. The ...
high-resolution images every second. Personal genomic information is encoded as genotypes for potentially millions of single nucleotide polymorphisms (SNPs). These numbers will only increase in the future as the resolution of data increases and new modalities are added to the mix, meaning that each ...
