learning, one needs to map hitherto unseen observations to a set of labeled examples and determine the label of the new observation. Given that we know the amount we want to difference our price series, fractionally differentiated features can be derived Learn more about bidirectional Unicode characters.

Although I don't find it that inconvenient. The favored kernel without the fracdiff feature is the sigmoid kernel instead of the RBF kernel, indicating that the fracdiff feature could be carrying most of the information in the previous model following a gaussian distribution that is lost without it.
