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 […]

The Lake Chelan Valley Scholarship Fund (LCVSF) received 48 applications for 2023 and has awarded 22 scholarships, each in the amount of $2500. Awards went to 7 previous award winners now in their second, third or fourth year of study, as well as 10 graduates from Chelan High School (CHS) and 5 graduates from Manson […]

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 […]

The Lake Chelan Valley Scholarship Foundation (LCVSF) will award 20 scholarships this year to college bound seniors and previous awardees. Recipients are from Chelan Valley schools including Chelan High School (CHS) and Manson High School (MHS). Two graduates from MHS class of ’22 will receive awards: Anthony Martinez and Francisco Munoz; seven members of CHS class of ’22: […]

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 […]

For 2021 the Lake Chelan Valley Scholarship Fund (LCVSF) will award 18 scholarships to college bound seniors and previous awardees currently attending. Recipients are from Chelan Valley schools including Chelan High School (CHS) and Manson High School (MHS). Included this year are three graduates from MHS class of ’21: Jonathan Fernandez, Cody Fitzpatrick and Zoe […]

The development of a machine learning model is typically a fairly involved process, and the software for doing this commensurately complex. Whether it be a Partial Least Squares (PLS) regression model, Artificial Neural Network (ANN) or Support Vector Machine (SVM), there are a lot of calculations to be made to parameterize the model. These include […]

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! […]

The Lake Chelan Valley Scholarship Fund has announced 15 award recipients for 2020. The scholarships go to college bound seniors from Chelan Valley schools including Chelan High School and Manson High School, and also renewals for previous award recipients. This year’s crop includes three graduates from this year’s MHS class: Brenda J. Alonso Arreola, Nadia […]

We started running “how to” webinars with our chemometrics software in the Fall of 2019. When COVID hit we decided to step up the frequency of these, and to add short courses. Up to now we’ve done ten webinars and five short courses running from 2-5 days each. Both have been quite popular. We’ve had […]

I just finished reading “Bad Blood: Secrets and Lies in a Silicon Valley Startup” by John Carreyrou. It is the story of Theranos and its founder Elizabeth Holmes. Our Bob Roginski sent it to me after I mentioned that I’d seen the HBO documentary “The Inventor: Out for Blood in Silicon Valley.” I highly recommend […]

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 […]
