Selecting Milk Spectra to Develop Equations to Predict Milk Technological Traits

open access: yesFoods, 2021
Including all available data when developing equations to relate midinfrared spectra to a phenotype may be suboptimal for poorly represented spectra. Here, an alternative local changepoint approach was developed to predict six milk technological traits ...

A family of regression methods derived from standard PLSR [PDF]

open access: yesChemometrics and Intelligent Laboratory Systems, 2013
The standard PLSR is presented from a geometric point of view consisting of two projections. In the first, the scores are obtained after an oblique projection of the spectra onto the loadings. In the second, the vector of response values is projected orthogonally onto the scores. A metric is introduced for the oblique projection and a new algorithm for

Predicting calcium in grape must and base wine by FT-NIR spectroscopy [PDF]

open access: yes, 2018
Calcium content in sparkling wines may not exceed 80 mg/L due to the risk of aggregation with alginate capsules. The high calcium content usually found in wine and must emphasizes the need to develop alternative and appropriate techniques faster and ...

Analysis of hidden information - PLSR on XRD raw data [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Usually in XRPD we are paying lots of attention to accurately describe profile shapes. We do that to eventually extract/predict information from the full pattern using physical models and fitting techniques. Sometimes this approach is stretched to its limits.

Mapping Soil Organic Carbon for Airborne and Simulated EnMAP Imagery Using the LUCAS Soil Database and a Local PLSR

open access: yesRemote Sensing, 2020
Soil degradation is a major threat for European soils and therefore, the European Commission recommends intensifying research on soil monitoring to capture changes over time and space.

Visible and near infrared spectroscopy in soil science [PDF]

open access: yes, 2010
This chapter provides a review on the state of soil visible–near infrared (vis–NIR) spectroscopy. Our intention is for the review to serve as a source of up-to date information on the past and current role of vis–NIR spectroscopy in soil science.
