Non-linear iterative partial least squares
Term · Chemistry · MLC-T-CHM-008035
An algorithm used in chemometrics to compute principal components and perform partial least squares regression, particularly for large data matrices. The method iteratively calculates the loading vectors and score vectors for each component without first computing the full covariance matrix of the data. This iterative approach makes it computationally efficient for analyzing datasets with many variables, such as those from spectroscopic measurements.
