Jun 28, 2009

After SSC11 I got a note from my colleague Paman Gujral at the Automatic Control Laboratory at EPFL summarizing some of the talks. He wrote: “Rasmus Bro gave an excellent talk too about the pitfalls in using chemometric methods. Kowalski commented that software firms are a lot to blame for advocating methods that don’t work.” […]

Referencing Software – Summary

Jun 27, 2009

The post I wrote on June 11, Referencing Software, resulted in a rather lengthy thread on ICS-L, the Chemometrics discussion list. Most discussants generally agreed that the software used to develop results for scientific papers should be referenced, including the software title, publisher, year and version number. There were a few dissenters. Sergey Kucheryavski wrote: […]

Use of Unlabeled Data in Regression Modeling

Jun 7, 2009

In 1995 Edward V. Thomas published “Incorporating Auxiliary Predictor Variation in Principal Components Regression” in J. Chemometrics, (vol. 9, no. 6, pps 471-481). Thomas demonstrated how additional samples, without matching references values, can be used when building a PCR model. These samples, commonly called “unlabeled data,” help stabilize the estimates of the principal components. So […]
