Formulation of the timing problem

Unlike intonation, timing synthesis can timing S5mthesis can in fact be formulated as a regression algorithm directly as our goal is to predict a single continuous value from a set of features. Re- 

Apart from the fact that we are predicting a continuous value instead of a class label, this formulation is the same as we have been using throughout the book for other classification problems and so it is natural to apply these approaches directly to the duration problem. In addition to these, a number of speeialised approaches have also been developed for use with this problem.
