Statistical Process Monitoring with Biogeography-Based Optimization Independent Component Analysis

Algorithm 1

Process monitoring using BBO-ICA.

Choose independent components to estimate

Set counter

Center the mean of each variables to zero

Unitize the variance of each variables to one

Perform whitening transformation to and get

Initialize parameters of BBO algorithm

Employ BBO to extract independent component of maximum independence and get

Output vector , update the observation matrix
