Following other works in this area, we propose a new machine learning system based on several protein descriptors extracted from several protein representations, such as, variants of the position specific scoring matrix (PSSM) of proteins, the amino-acid sequence, and a matrix representation of a protein.
Some equations were based on several topological descriptors: MCI, the number of path length (P7, P10), the Balaban index based on distance (Jb), the Wiener index (W), and information indices (CIC, IC, SIC) led to good estimate of KOW of various organic compounds (r > 0.652; Table S4; Basak et al., 1996; Dai et al., 1998; Niemi et al., 1992).
Finally, for 387 miscellaneous compounds, the Koc was estimated using several moment descriptors (M0, M2, M3, Macc, Mdon; Klamt et al., 2002), and for 65 PCOC, the relationship based on several quantum-chemical descriptors such as EHOMO, TE or μ showed good results (r = 0.854; Table S7; Dai et al., 1999; Table S7).
More complex models, based on several molecular properties and descriptors, have been recently developed [83 85].
In this study, we used the same feature set, a set of 1,532 acoustic features based on several acoustic low-level descriptors (LLDs) and statistics (functionals), used in the INTERSPEECH 2010 Paralinguistic Challenge [32].
Selection between models was based on several factors: (i) visual inspection of goodness-of-fit plots for several descriptors of CEL profiles; (ii) the objective function value; and (iii) the precision of the parameter estimates.
That assessment was based on several considerations.
"It was based on several.
This hypothesis was based on several points.
Interest rates vary based on several factors.
