However, it generates high-dimensional sparse data matrix with a high feature-to-instance ratio.
Each dissimilarity space is a transformation of the original space that reduces the dimensionality, feature-to-instance ratio, and sparseness.
High dimensionality This occurs when the feature-to-instance ratio is very large and is a common characteristic of big data.
For instance, specific ratios among subunits are required for formation of protein complexes, which are major components of biochemical networks.
For instance, the ratios of lengths between females and males were 0.58, 2.64 and 1.52 on LG1, LG15 and LG20, respectively (see Additional file 3: Table S2).
For instance, decreased ratios between Faecalibacterium prausnitzii and Escherichia coli in IBD patients resulted in different fecal bile acid compositions, with implications in the perpetuation of chronic inflammation in IBD [ 5].
For instance, C/N ratios are high in fresh plant litter, but decrease during decomposition, since C is lost at higher rates than N [ Sterner and Elser, 2002; Mooshammer et al., 2014b].
For building frame systems, various codes present the numerical values of the ratio between Cd and R. For instance, this ratio for concentrically steel braced frames is from 0.5 to 1 in NEHRP (1994) and IBC (2000) and is equal to 0.7 in the Iranian Earthquake Resistance Design Code Standardd No. 2800 BHRC 200505).
For instance, the ratio of rural doctors to rural population is far less or poor than the ratio of total doctors to total population [ 5].
