Swiss knife covariates selection: A unified algorithm for covariates selection in single block, multiblock, multiway, multiway multiblock cases including multiple responses

Abstract: A novel unified covariates selection algorithm called Swiss knife covariates selection (SKCovSel) is presented. It is suitable for selecting covariates in a wide range of data scenarios such as a single two‐way data block, two‐way multiblock, multiway, multiway multiblock, selection of covariates along different modes for multiway data blocks and for selecting covariates for all mentioned cases in multiple response scenarios. In the multiblock case, the method can be scale and data block order‐independent depe… Show more

“…Furthermore, the residuals from multiple responses can be jointly handled as a product as done in earlier works 18,26 . The same algorithm can also be adapted to do higher order robust feature selection 18 for multilinear data with methods such as N‐way covariates selection 31 . The feature selection step will involve binarising the robust loading weight vector using a criterion such as maximum covariance.…”

“…This kind of block division was suggested by Zhu et al 37 who argued that the condenser and compressor both involve just one measured variable, and they could more appropriately be allocated to the nearby reactor and separator blocks, respectively. If the interaction between the production units is additionally considered, an overlapped block division (marked as MB3) proposed by Wan et al 21 could also be a rational choice, which is detailed in Table 3.…”

“…[18][19][20] With respect to the increasing scale of modern chemical processes, distributed process monitoring has been a growing branch for the last decade. [21][22][23][24][25][26] Because large-scale chemical processes generally consist of multiple units as well as plenty of measured variables, the interpretability of data-driven models could be enhanced if the normal variation in the given dataset is modeled from multi-block or distributed aspect. 21 Mishra et al 22 provided a comprehensive review for recent trends in multi-block data analytical methods.…”
