Adaptive Sparse Multi-block Partial Least Square (asmbPLS), a supervised algorithm, is an extension of the smbPLS, which allows different quantiles to be used in different blocks of different PLS components to decide the proportion of features to be retained. The best combinations of quantiles can be chosen from a set of user-defined quantile combinations by cross-validation. By doing this, asmbPLS enables us to do the feature selection for different blocks, and the selected features can then be further used to predict the outcome. For example, in biomedical applications, clinical covariates plus different types of omics data such as microbiome, metabolome, mRNA data, methylation data, and CNV data might be predictive for patients’ outcomes such as survival time or response to therapy. Different types of data could be put in different blocks along with survival time to fit the asmbPLS model. The fitted model can then be used to predict the survival of the new samples with the corresponding clinical covariates and omics data.
In addition, Adaptive Sparse Multi-block Partial Least Square Discriminant Analysis (asmbPLS-DA) is also included, which extends asmbPLS for classifying the categorical outcome.
