DSC_Window | R Documentation |
Interface for DSO_Window. Represents the points in the sliding window as micro-clusters.
DSC_Window(horizon = 100, lambda = 0)
horizon |
the window length. |
lambda |
decay factor damped window model. |
If lambda
is greater than 0 then the weight uses a damped window
model (Zhu and Shasha, 2002). The weight for points in the window follows
2^{-lambda*t} where t is the age of the point.
An object of class DSC_Window
(subclass of DSC,
DSC_R, DSC_Micro).
