  • Smarter Geotech Starts With Digital Twins

    Over the past year, I’ve come across the term “digital twin” quite a bit, a term I really like because it sounds pretty cool! So I started gathering information to see how it could be applied in geotechnical engineering. This week’s article is all about that. I’ve never applied it myself, but I hope this…

  • More Data, Better Model? Not Always!

    At the GeoCongress 2023 conference in LA, I had an interesting conversation with a geotechnical engineer about a Bayesian correlation model we developed. The model correlated cone penetration tip resistance with standard penetration test (SPT) blow counts in sandy soils, using 220 high-quality data points from previous research. His reaction? “Wait, just 220 points? And…

  • Simplicity vs. Complexity in ML Models: Are We Overcomplicating Things in Geotechnical Engineering?

    A while back, we wrote a research paper on this very topic (I’ll drop the link below), and the question still stands: Do we really need complex models all the time? Over the past two decades, AI and ML have made their way into geotechnical engineering, and it’s been exciting to see. Researchers have developed…

  • Your Geotechnical Machine Learning Model is Probably Unusable – Here’s Why

    Over the past three years, I’ve had a great opportunity to review tens of research papers applying machine learning to geotechnical problems: slope stability, soil classification, predictive modeling, you name it. And while I genuinely appreciate the effort researchers put into these studies, I’ve noticed a pattern: Many of them are just chasing the AI/ML…

  • MUSIC-3X: A Simple Way to Summarize Geotechnical Data Challenges

    Data quality is everything when it comes to machine learning or data-driven applications in geotechnical engineering (or any field, actually). No matter how advanced your model is, if the data isn’t solid, the results won’t be either. That’s why I believe the first step in applying AI to geotechnical problems is to truly understand the…
