A Classifier Graph Based Recurring Concept Detection and Prediction Approach

Algorithm 1

The pseudocode of DBDM.
Algorithm 1: Distribution-Based Detection Method
Input: S: data stream, m: size of block, , ;
Output: flagWarning;
begin
flagWarning = false;
for each instance in S do
numInstance++;
if numInstance % m == 0 then
for each check point Pi do
compute mean values and ;
compute and using Šidák correction;
compute and ;
if then
delete instances which are on the left side of Pi;
if then
return true;
break;
end if
if then
flagWarning = true;
end if
end if
end for
return flagWarning;
end.
