Wonderful hosting Ruben Van der Stichelen again in the QuNB lab during a quick hop from his @fwovlaanderen.bsky.social long stay abroad at the Izmaylov lab at UofT. Quantum chemistry in the age of NISQ and the seniority quantum number. (1/2)

Wonderful lecture by Dr. Tomoya Shiota from Osaka University to the QuNB group. Impressive progress on how to combine #compchem data from seemingly disjoint datasets (inorganic vs organic) and how to make them work together in a transparent ML framework. (1/2)
Slide from Dr. Tomoya Shiota’s presentation for the QuNB group titled Machine Learning Interatomic Potentials.

The flex to go into a pagelong “clarification” to the reviewer, but then change nothing to your manuscript, will never cease to bewilder me….

One thing I always appreciate about seminar abstracts from mathematicians is the courtesy towards their collaborators: “Joint work with X & Y” 🙇‍♂️

When a Machine Learning model trains on just DFT energies, does it pick up there is an underlying quantity that governs the data: the electron density? We set out to investigate that question, and looked at electron populations in very much the same way we looked at embedding representations (1/5)
