Evaluating Models: Hating on R-squared

Jun 16, 2022

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.” […]

Python is free

Apr 5, 2022

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 […]

We used to call it “Chemometrics”

Feb 23, 2022

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, […]

Remembering Svante

Jan 6, 2022

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 […]

Under Same (Old) Management

Oct 21, 2021

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 […]

The Model_Exporter Revolution

Jan 28, 2021

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 […]

New Year, New Courses and Webinars

Jan 12, 2021

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 […]

Year 27

Jan 5, 2021

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! […]

How to Run a Webinar or Online Course

Jul 8, 2020

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 […]

Sociopaths, Enablers and Due Diligence

Apr 15, 2020

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 […]

COVID-19 Upate: Still Here to Help You

Mar 18, 2020

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 […]

Domain Knowledge and the New “Turn Your Data Into Gold” Rush

Jan 29, 2020

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 Turns 25

Jan 1, 2020

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 […]

Everybody’s Welcome in the Eigenvector Sandbox

Nov 20, 2019

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 […]
