The descriptors need to include key points and pixels that contribute to the key points.
An example is RegioSelectivity (RS -predictor [14, 15] which uses a SuppoRS -predictorhine (SVM) to predict SoM using 148 topological and 392 quantum chemical atomic descriptors where some of these descriptors are modified to include contributions from neighbouring atoms.
A further improvement of these descriptors would be to include proximity and order of the sequence motifs in the promoter regions [ 28], however, such information was not utilized in this study.
Due to the small sample size, we are unable to include descriptors regarding the participants so to preserve their anonymity.
The number of terms (number of descriptors) to be included in the final GQSAR model was kept as 3.
Various statistical techniques were used to correlate descriptors to biodegradation data, including linear, multilinear, and nonlinear (e.g., neural networks) regressions; classification tools; and expert system based on if-then-else rules and artificial intelligence (Baker et al., 2004; Blockeel et al., 2004; Cuissart et al., 2002; Gamberger et al., 1996; Tabak and Govind, 1993).
PEGI 7+ games flagged with a violence descriptor may include "non-realistic violence towards fantasy characters" or "implied violence".
They use different topological descriptors, again easy to calculate, include an evaluation of synthetic accessibility and favour self-organising maps (SOM) for data visualisation.
The pain descriptors used by patients also varied, but were consistent irrespective of NP type and very also similar to the descriptors included in the McGill short form pain questionnaire where pain is referred to as debilitating, burning, sharp, jabbing, deep, and aching, and can persist for months or years [ 36, 37].
