Table 1 summarizes the main chara [...] the se- quence of tokens x = (x1. . . xT ) or the sequence of labels y = (y1. . . yT ). Subse- quences are denoted using superscripts, as in y{t"k..t"1} = (yt"k. . . yt"1). We call X the set of possible [...] y{t"k..t"1}, yt
#$ t = 1...T ,
where w $ RD is a parameter vector and function !g : X % Yk % Y & RD de- termines the feature space.
