Back from beautiful Lausanne where I was a member of the jury for Ayatallah Elakhras' PhD "Efficient Data Steering in Dataflow Circuits". Congratulations to Aya!
(Also to advisors Ienne and Josipović.) It was great working with Bourgeat, C…
In 1967, Wyner published the paper "Random Packings and Coverings of the Unit n-Sphere" in the Bell Syst. Tech. J. (link below). This showed that the number of spherical caps of angular radius theta required to cover an n-dimensional spher…
My latest (and probably final) blog post on block number formats and direction preservation. This time I deal with the number formats for scale factors. https://constantinides.net/2026/06/11/precision-matters-in-block-scales/
The House of Commons Science, Innovation and Technology Committee has published my written submission to their inquiry "Low-energy computing" which means I am now free to publish it here: https://committees.parliament.uk/writtenevidence/16…
I have written an accessible blog post on the recent preprint I published with Bardia Zadeh on taking a geometric view on what low precision means for vector representations, especially relevant to block arithmetics.

Congratulations again to my freshest PhD graduates who attended their ceremony at the Royal Albert Hall today. Here I am with Martin Langhammer and Benjamin Biggs. Celebrations all round!
I had the immense pleasure of joining colleagues from across Europe at University of Geneva last week for the LERU DOCT policy group.
Delighted to have joined the group as a steering committee member. Looking forward to working with LER…
Zadeh and I have uploaded a new preprint: Direction-Preserving Number Representations.
Spoiler: FP is provably suboptimal but NVFP4 does a pretty good job!
We have Lean proofs:

Had a great away day with the Imperial Early Career Researcher Institute team yesterday at our White City campus. It was great to see the alignment in values coming through so strongly.
