Dimension reduction is important during the analysis of gene expression microarray data, because the high dimensionality in the data set hurts the generalisation performance of classifiers. Partial Least Squares Based Dimension Reduction (PLSDR) is a frequently used method, since it is specialised in handling high dimensional data set and leads to satisfying classification performance. However, the previous works exist an ambiguous usage of projection weights in PLSDR. To assure the orthogonality of projected components, the usually used project weights are nonorthogonal. Here, we propose to use orthogonal project weights for PLSDR. Experimental results on four microarray data sets show our proposed orthogonal project weights are better than the previous used to help improve the generalisation performance of classifiers.
