We have used transferable atom equivalent (TAE) descriptors [116,117] that encode the distributions of electron density based molecular properties, such as kinetic energy densities, local average ionization potentials, Fukui functions, electron density gradients, and second derivatives as well as the density itself. In addition autocorrelation descriptors (RAD) were used and represent the molecular geometry characteristics of the molecules, while they are also canonical and independent of 3D coordinates. The 2D descriptors alone or in combination with the latter 3D descriptors were calculated for 26 data sets collated by us from numerous publications. These data sets encompass various ADME/TOX-related enzymes, transporters, and ion channels as...

Wavelet coefficient descriptors (WCDs) ° exemplify how the WT enhances the quality of current descriptor technology and enables the development of improved models. WCDs are an adaptation of the transferable atom equivalent (TAE) descriptors developed by Breneman and Rhem. TAE descriptors are derived by quantifying the distributions of multiple electronic properties computed on electronic van der Waals surfaces, which are defined as the 0.002-e-au isosurfaces (Figure 15). TAE descriptors encode the... 

Another approach is to calculate more abstract descriptors, which themselves can be treated as latent variables. Examples of these are Breneman s transferable atom equivalents (TAEs) (20) and Pearlman s BCUT descriptors (21). TAEs are the result of various mathematical simplifications of a molecule s ab initio electronic distribution, mapped to its surface BCUTs are computed as...
