Fem regler for KI-resistent forskning
Det er helt nødvendig at vi forskere lærer å gjenkjenne typiske KI-feil både som lesere og som skribenter, skriver KI-forsker Jill Walker Rettberg.

Excited about this new pre-print with colleagues in Oslo, providing 'posterior'-type uncertainty for kernel density estimators via the Martingale posterior framework.

I have just resigned from the board of "Statistics and Computing", along with 17 other Associate Editors. This was a difficult decision: this great journal has published many tremendous articles under the leadership of EiC Ajay Jasra, and before him David Hand, Gilles Celeux, and Mark Girolami.

I to og et halvt år har disse to messet om at Oslo står på kanten av det økonomiske stupet. Jeg har ikke tatt det med en klype salt, men en sekk grov havsalt. Les, lik og del (som vi sa i gamle dager).

Flott av Inga Strümke i Morgenbladet, setter ord på mye som jeg selv har tenket på det siste året, og som jeg tror mange andre som jobber med ML fra matematikk / statistikk siden tenker.

(+) Inga Strümke: – Spekulativ skit fortrenger viktige diskusjoner
Skrekkscenarioene fra Silicon Valley og tankesmien Langsikt bidrar til PR for KI-bransjen og skygger for viktigere diskusjoner, mener Inga Strümke.

autodiff is cool and all, but have you tried manually computing the gradient to avoid too many variables on the autodiff tape..??? (screenshot of me trying to avoid autodiffing through large Gram matrices)

Playing around plotting some chemical structure embeddings coming from a VAE, and colouring by local intrinsic dimension looks almost like these colour blind test images.

Glad to see this happening! I never understood why UK dads were not marching in the street already when I saw that my UK employer only offered *two weeks* paternity leave. Coming from Norway I had to trade in a minimum 4 months leave for a measly two weeks -- time with my daughter I won't get back.

Working on a model involving some GP regression, coupled with a horseshoe prior for variable selection. In an attempt at counting the number of effective parameters of my model, the following quantity pops out quite naturally. Is this a well known quantity? 1/2
Here, in the context of GP regression, K refers to the n x n Gram matrix associated with a set of inputs and a covariance function, while lambda_j refers to the eigenvalues of K.

Tvert i mot, dette er på alle måter et skattemessig smutthull. Det er faktisk nøyaktig hva det er: Noe som teknisk sett ikke er ulovlig, men åpenbart heller ikke i tråd med intensjonen. Intensjonen er neppe at eiendomsbaroner skal få skattefritak.
Engebretsen viser til at Skatteetaten fleire gonger har fått spørsmål om burettslagsmodellen er lovleg, noko dei har stadfesta at han er.

Leiv Rønneberg @ltronneberg.bsky.social · 01/12/2024
Like, I get that I shouldn't, but it is surprisingly easy to do inference for a very basic BNN in Stan. Just standard NUTS. The sampler complains a lot, but intervals and mean look sensible enough
