Description Usage Arguments Value
The predictive model is based on a "colinearity" argument between one day and the other Each traning sample consists of two consecutive days (Ltoday,Ltomorrow). A dictionary is then learnt to represent a set of training samples with that form. The dictionary will then be an ensemble of two-day atoms, the upper part corresponding to "todays", and the lower part to "tomorrows", [Dtod^T Dtom^T]^T To predict tomorrow's load, w represent today's load Ltod in terms of Dtod and obtain a set of coefficients a Whe then estimate Ltom as Dtom*a. The underlying hypothesis is that "a" would be essentially the same if we had asked to represent the whole vector [Ltod,Ltom]
