The pseudo code of the PAA Algorithm |

Piecewise Aggregation divides the original data of length
better reconstruction of the original data, however more data space is needed to store the data and eventually higher energy consumption by higher communication costs Suppose the following: “D” is the list of data that containing the raw values that we will reduce it’s size, “L” is the desired output length, “w” is the number of equally sized windows, “output” is the result vector of PAA function, “p” is the pointer to the data list, “s” is the segment. “n” is the iterator over output vector
function PAA(L, D) w:= length(D)/L p=0 n=0 output[] // initialize the output vector of length L while p < length(D) do // iterate over the s:= D output p = p + w //increase the value of the pointer with value of “w” n++ // increase the value of the output vector iterator end while return output // return the output vector after iterating over the data end function |
