Style of a text is a very general notion that is hard to define in rigorous terms (Xu, 2017).
the style of a text can be characterized quantitatively (Hughes et al., 2012); stylized texts could be generated if a system is trained on a dataset of stylistically similar texts (Potash et al., 2015); and authorstyle could be learned end-to-end (Tikhonov and Yamshchikov, 2018b,c;.
