A simple and statistically significant QSAR model (F = 33.83, R2 = 0.87) was successfully developed for the dark group based on two descriptors, absolute electronegativity of the metal and the metal oxide.
Remarkably, the best prediction system based on three descriptors yielded a validated accuracy of 84.6 %.
Using the workflow explained below, we collected 167 models featuring a nonvalidated accuracy of 100%%, based on three and four descriptors.
In summary, the SVM classification is based on seven descriptors, of which four, Δ meanmfe, Δ meanz, Δ consmfe and Δ sci directly measure differences between the reading directions, while the remaining three, n, H, and λ GU provide information on the structure of the input alignment that allow the SVM to interpret the significance of strand differences.
a Cross-validation performance of PCM model constructed by RF classifier based on four different protein descriptors.
The local surface types and the characteristic points are first recognized based on two surface descriptors: shape index and curvedness.
Furthermore, an automatic classifier based on two audio descriptors and a multinomial logistic regression procedure is implemented and validated with the corpus.
In 2001, Lipkus proposed a simple strategy to organize chemical rings based on three integer descriptors, and he found that the distribution of 40,182 different ring topologies derived from a comprehensive collection of chemical rings from the CAS registry was not compact and had many significant voids [17].
Genotyping of the whole mungbean collection currently consisting of more than 6,700 accessions was out of scope for the present study, therefore the AVRDC – The World Vegetable Center mungbean core collection was established by geographical stratification of the whole collection comprising more than 5,000 accessions and subsequent diversity analysis based on eight phenotypic descriptors.
Iveel et al. [29] extracted motion trajectories after video segment and build a bag-of-features (BOF) model based on four different types of descriptors (i.e., HOG, HOF, MBH, and TS).
