Belfort released a nice homomorphic encryption demo today: CIFAR-10 inference in CKKS with GPU acceleration in 163ms. With round-trip latency, it's 200ms. Live web demo here: sofar.belfortlabs.cloud Some more details on their blog belfortlabs.com/blog/sofar

Philosophers, we need your help We are running a study on philosophers’ intuitions about thought experiments moralsciencelab.com/intuitions/ Only takes a few minutes!

Most of the statistical tests you learned in stats class — t-test, ANOVA, correlation — are actually special cases of a single thing: linear regression. Ch 7 of Experimentology argues that thinking in models, not tests, is more flexible and a better foundation for theory. 🧵 experimentology.io

Adding this to my To Read list. Unfortunately, even just the abstract will teach you more than most people know. #OpenScience

Hmmm. The example videos involve #GenAI doing a lot of interpretative work, which is harder to check for inaccuracies than verifiable work like asking for three differentiations for a lesson plan. #GenAI could augment teachers' expertise, but I worry about it black-boxing important interpretations.

1/ Anthropic launched Claude for Education today, it feels like more than another AI product announcement. It looks like a strategic play to become the infrastructure layer for education rather than simply another classroom tool. www.anthropic.com/news/claude-...

Today we launch the first stable release of RegCheck: v1.0.0. RegCheck makes it easier and quicker to compare study registrations to published papers for consistency - something we know is important in principle, but rarely done in practice. A 🧵 on what's new: regcheck.app

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.

WE ARE HIRING! Come work with us (me + @malte.the100.ci) on developing and validating RegCheck. PhD or postdoc applications welcome. Folk with backgrounds in meta-science, psychology, (pre)clinical trials, and/or economics are especially invited to apply. jobs.unibe.ch/job-vacancie...

Very happy to see this out! Our new paper, "Boosting Media Literacy Using Lateral Reading and Online Search Interventions," is now published in Psychological Science.

This part of history touched my family in profound ways. My fist to my heart if it hit you and yours, too.

AUTOMATING COMPUTATIONAL REPRODUCIBILITY My colleague @philipjakobbln.bsky.social and I are currently engaged in a research project where we reproduce scientific results en masse. To that end, we built rigor.me, a platform for automatically reproducing papers using agents 🧵

No less than 60 million stars in one image. It's possible thanks to ESA's Euclid mission. For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light. Let's dive deeper 👇 🔭 🧪 ☄️ 1/8

Funny! We came across this literature (which uses signature size as a PROXY for narcissism) and had a similar reaction. We (@juliastern.bsky.social + Natalie Popov) ran a study (N = 417) to test how “robust” the relation is. Surprise. No relation at all. Seems like we need to write this up?

The standard random-effects model in meta-analysis assumes that the amount of heterogeneity is homoscedastic. This assumption may not be true. I derived and examined various tests for heteroscedastic heterogeneity. See osf.io/cavhy for a preprint describing these methods. #MetaAnalysis #RStats

What can surveys miss when respondents choose the same answer option? In this pre-print, we argue that public opinion research needs not only to know where respondents stand, but how they think. AI Conversational Interviewing is one way to make that observable at scale

Someone here works with the intersection of mental health & measurement & or metascience? I'm looking for a few collaborators for a project that uses Large Language Models. Feel free to get in touch.

OK all you ML experts I have a dumb question. Context: I am looking at MobileNetV3, which takes a 2D convolution and splits it into depth-wise and cross-channel convolutions with a hard-swish in between.

In large meta-analyses, standard forest plot can become excessively large. One solution is to group the estimates together within studies. I just added an example to the metafor website illustrating this possibility: www.metafor-project.org/doku.php/plo... #MetaAnalysis #RStats

Have you seen MATILDA (matilda.fss.uu.nl)? Which stands for Measurement, Analysis & Theory for Intensive Longitudinal Data. MATILDA is a website with educational articles that help researchers align theory, measurement, and analysis when studying processes using intensive longitudinal data.

🚨Out today in @nature.com our new paper uses deep learning to map four decades of global human migration. By building the first comprehensive, four-decade dataset of annual flows (1990-2023), we reveal that global migration has nearly tripled since 2000. 🔗 www.nature.com/articles/s41...

I'm having fun with this 1001albumsgenerator.com things, but it's really teaching me how picky I am with music. I have listened to ~50 albums so far and there was only really one album I enjoyed that I didn't know in advance I was going to enjoy (KIWANUKA by Michael Kiwanuka),

For detecting careless respondents, if interested in learning how several univariate cutoffs for outlier statistics (e.g., Mahalanobis distance, person-total correlation) can do, Michael Ilagan, Wenshuo Li and I also developed an #rshiny app to teach about this. falkcarl.shinyapps.io/BotApp2/

Better methods are available. This Shiny app is related to new research that I will share soon (led by Wenshuo Li with Michael Ilagan and I), as well as Michael Ilagan’s dissertation and the detranli R package: github.com/falkcarl/det... #SurveyResearch #DataQuality #Psychometrics
