We also note that non-linear models methods, such as neural networks (Schwenk et al., 2006;Kalchbrenner and Blunsom, 2013;Devlin et al., 2014;Cho et al., 2014) and decision forests (Criminisi et al., 2011) are not bound by these analyses.
neural networks are non-linear functions of the features, and decision forests actively reduce the number of features for individual trees in the forrest.
