Cage of covariance in calibration modeling: Regressing multiple and strongly correlated response variables onto a low rank subspace of explanatory variables
Eskildsen, Carl Emil Aae; Næs, Tormod; Skou, P.B.; Solberg, Lars Erik; Dankel, Elin Katinka; Basmoen, Silje A.; Wold, Jens Petter; Horn, Siri S.; Hillestad, B.; Poulsen, Nina A.; Christensen, Mette; Pieper, Theo; Afseth, Nils Kristian; Engelsen, Søren B. (Peer reviewed; Journal article, 2021)In analytical chemistry, multivariate calibration is applied when substituting a time-consuming reference measurement (based on e.g. chromatography) with a high-throughput measurement (based on e.g. vibrational spectroscopy). ... -
Calibration transfer between different spectrometers by wavelength correspondence
Tengstrand, Erik; Solberg, Lars Erik; Dankel, Elin Katinka; Lintvedt, Tiril Aurora; Afseth, Nils Kristian; Wold, Jens Petter (Peer reviewed; Journal article, 2024)In this paper we present a method for transferring calibrations between different spectrometers based on assigning wavelength correspondence. It has been tested for near-infrared (NIR) and Raman spectroscopic instruments, ... -
Diagnosing indirect relationships in multivariate calibration models
Eskildsen, Carl Emil Aae; Engelsen, Søren B.; Dankel, Elin Katinka; Solberg, Lars Erik; Næs, Tormod (Peer reviewed; Journal article, 2021)Problems concerning covariance among independent variables are well understood and dealt with by inverse regression methods like partial least squares regression. However, covariance between dependent variables has only ... -
Diagnosing the cage of covariance to increase understanding and robustness of spectroscopic calibration models
Tengstrand, Erik; Måge, Ingrid; Solberg, Lars Erik; Afseth, Nils Kristian; Wold, Jens Petter (Peer reviewed; Journal article, 2024) -
Improved control of Listeria monocytogenes during storage of raw salmon by treatment with the fermentate Verdad N6 and nisin
Heir, Even; Solberg, Lars Erik; Carlehög, Mats; Moen, Birgitte; Jensen, Merete Rusås; Holck, Askild Lorentz (Peer reviewed; Journal article, 2021)Fresh Atlantic salmon (Salmo salar) represents a healthy, nutritious food with global distribution and increasing consumption and economic value. Contaminating Listeria monocytogenes in fresh salmon represents a health ... -
Improved microbial and sensory quality of chicken meat by treatment with lactic acid, organic acid salts and modified atmosphere packaging
Heir, Even; Solberg, Lars Erik; Jensen, Merete Rusås; Skaret, Josefine; Grøvlen, Magnhild Seim; Holck, Askild Lorentz (Peer reviewed; Journal article, 2021)Microbial contamination and growth play important roles in spoilage and quality loss of raw poultry products. We evaluated the suitability of three commercially available organic acid based antimicrobial compounds, Purac ... -
In-Line Estimation of Fat Marbling in Whole Beef Striploins (Longissimus lumborum) by NIR Hyperspectral Imaging. A Closer Look at the Role of Myoglobin
Wold, Jens Petter; Solberg, Lars Erik; Øvrum Gaarder, Mari; Carlehög, Mats; Sanden, Karen Wahlstrøm; Rødbotten, Rune (Peer reviewed; Journal article, 2022) -
In-Line Near-Infrared Spectroscopy Gives Rapid and Precise Assessment of Product Quality and Reveals Unknown Sources of Variation—A Case Study from Commercial Cheese Production
Solberg, Lars Erik; Wold, Jens Petter; Dankel, Elin Katinka; Øyaas, Jorun; Måge, Ingrid (Peer reviewed; Journal article, 2023)Abstract: Quality testing in the food industry is usually performed by manual sampling and at/offline laboratory analysis, which is labor intensive, time consuming, and may suffer from sampling bias. For many quality ... -
Making sense of multiple distance matrices through common and distinct components
Solberg, Lars Erik; Dahl, Tobias Gulden; Næs, Tormod (Peer reviewed; Journal article, 2021)Multiblock analysis attacks the problem of how to combine data from various data sources for purposes such as prediction, classification, clustering, or visual data analysis. A key concept is the distinction between “common” ... -
