Online Processing
Online processing computation mode assumes that data arrives in blocks .
Computation of low order moments in the online processing mode follows the general computation schema for online processing described in Algorithms.
Algorithm Input
The low order moments algorithm accepts the input described below. Pass the Input ID as a parameter to the methods that provide input for your algorithm. For more details, see Algorithms.
Input ID |
Input |
---|---|
data |
Pointer to the numeric table of size that represents the current data block. While the input for defaultDense, singlePassDense, or sumDense method can be an object of any class derived from NumericTable, the input for fastCSR, singlePassCSR, or sumCSR method can only be an object of the CSRNumericTable class. |
Algorithm Parameters
The low order moments algorithm has the following parameters:
