Year 30

Dec 27, 2023

I believe that days go slow and years go fastAnd every breath’s a gift, the first one to the last – Luke Bryan, ‘Most People are Good’ Eigenvector Research starts its 30th year this January. Reflecting on that made me think of the Luke Bryan quote above. Some days have been long, for sure. For […]

Jonathan Stratton of Optimal posted a nice summary on LinkedIn of the 2nd Annual PAT and Real Time Quality Summit which took place in Boston this month. In it he included the following bullet point: “The age-old concept of data modeling with spectroscopy has been revitalized through the integration of Machine Learning and AI initiatives. […]

At Eigenvector Research we offer many courses in chemometrics and machine learning and several ways to take them. As such, I often get variations on the question “what’s the difference between your in-person classes and your online classes?” I’ll address this by starting with what stays the same. We use the same notes, and have […]

Eigenvector Research produces a variety of software products for chemometrics and machine learning and we often get asked how they work together. Here’s the roadmap! We have two main packages for modeling, our MATLAB® based PLS_Toolbox, and our stand alone Solo (with versions for Windows, macOS and Linux). Solo is the compiled version of PLS_Toolbox, […]

In 1988 Donald Dahlberg, Professor of Chemistry at Lebanon Valley College (LVC), decided to take a sabbatical leave at the University of Washington (UW) Center for Process Analytical Chemistry (CPAC). At the time, his former student Mary Beth Seasholtz was a second year graduate student in Bruce Kowalski’s Laboratory for Chemometrics. Mary Beth asked Don […]

There are a number of measures that are used to evaluate the performance of machine learning/chemometric models for calibration, i.e. for predicting a continuous value. Most of these come down to reducing the model error, the difference between the reference values and the values predicted (estimated) by the model, to some single measure of “goodness.” […]

PLS_Toolbox is not free. But you don’t have to be a dedicated data scientist to use PLS_Toolbox (or its stand-alone equivalent Solo). Many of its users are, but the real expertise of most users is in something else such as analytical instrumentation (typically spectroscopy) or the specific problem they are working on (e.g. chemical process […]

The term chemometrics was coined by Svante Wold in a grant application he submitted in 1971 while at the University of Umeå. Supposedly, he thought that creating a new term, (in Swedish it is ‘kemometri’), would increase the likelihood of his application being funded. In 1974, while on a visit to the University of Washington, […]

Svante Wold passed away on January 4, 2022, at the age of 81. In the fields of chemometrics and data science, there is no need to use his last name. If you say “Svante,” everybody knows who you are talking about. I first met Svante almost 30 years ago at the Chemometrics in Analytical Chemistry […]

That’s not a headline you see very often. Usually it’s “Under New Management.” But here at Eigenvector Research we’re proud of our stability. I wrote the first version of our MATLAB-based PLS_Toolbox while I was in graduate school thirty-one years ago. I still oversee its development along with our other software products. In 1990 Partial […]

In response to the COVID-19 pandemic, in 2020 we offered many online courses, over 100 hours of lectures in total (not counting the classes we did for specific clients). We gave ourselves a break towards the end of the year but we’re now re-energized and ready to get going again. Our first webinar of the […]

And so it begins again! For the 27th time I’ve gotten up on the first business day of January looking forward to a new year with Eigenvector Research. The overall plan doesn’t change much: keep improving the software, provide training in data science/chemometric methods and help clients with their challenging data problems. But the details! […]

As with most of you, we here at Eigenvector are very concerned about the COVID-19 outbreak and its impact on our families, friends, customers and communities. We continue to monitor its evolution closely, especially in regard to our employees and their families. The direct effect of COVID-19 on the daily business of Eigenvector, however, is […]

A colleague wrote to me recently and asked if Eigenvector was considering rebranding itself as a Data Science company. My knee-jerk response was “isn’t that what we’ve been for the last 25 years?” But I know exactly what she meant: few people have heard of Chemometrics but everybody has heard about Data Science. She went […]

Eigenvector Research, Inc. was founded on January 1, 1995 by myself and Neal B. Gallagher, so we’re now 25 years old. On this occasion I feel that I should write something though I’m at a bit of loss with regards to coming up with a significantly profound message. In the paragraphs below I’ve written a […]

When I was a kid I was lucky to have a great sandbox. The fact that it was on the shores of Lake Chelan made it especially nice, but there were a lot of other things that made it great. First off, it was big enough for several kids to play in at the same […]

Eigenvector Reseach President and PLS_Toolbox creator Dr. Barry M. Wise was recognized for his achievements in the field of chemometrics* at the 16th Scandinavian Symposium on Chemometrics (SSC16) in Oslo, Norway. Wise received the Herman Wold Medal in gold “For his pioneering contributions in Process Chemometrics and his extensive, deep commitment to the proliferation of […]

When I was first introduced to image analysis by Paul Geladi he referred to it as Multivariate Image Analysis or MIA. So when we released our image analysis package back in 2005 we called it MIA_Toolbox. Since then more and more analytical techniques have been adapted to produce images. On the micro scale this includes […]
