Hi, I am using CUSUM (cumulative sum) algorithm to detect points of sudden changes in my neural signal data. This algorithm is working fine, but I want to try some other algorithm. Can anyone suggest some other algorithm that can be used to detect changes?

Just compare the new point with the old mean before updating the mean
check(n+1) = abs( x(n+1)- meanx(n) )
meanx(n+1) = ( x(n+1) + n*meanx(n))/(n+1)
Hope this helps
Thank you for formally accepting my answer
