Concerned about the environmental impact⚡💧 of AI/ML systems? Interested in doing a PhD in 🌞 Brisbane, Aus? I have PhD positions available exploring power and statistical efficiency in AI/ML/Stats! 👇 www.qut.edu.au/research/stu... www.qut.edu.au/research/stu... www.qut.edu.au/research/stu...

Maybe a hot take, but what about the following advice to the next gen: Don't get an AI degree; the curriculum will be outdated before you graduate. Instead, study math, stats, or physics as your foundation, and stay current with AI through code-focused books, blogs, and papers.

Universities and Institutions have to push back NOW. When they threaten one group of scientific institutions, if we are silent, we will be next. HHMI and the other potential targets need to work with red state Unis to stall this illegal targeting in courts. www.science.org/content/arti...

What fascinates me the most about people who think LLMs are in any way reliable is that they've clearly never asked an LLM for information on literally anything they know the answer to themselves 😅 For what it's worth, today is Monday, February 10, so third time lucky (fourth time not so much)

“Why do I need NOAA? I’ve got a weather app.” Is equivalent to asking “Why do I need farms? I can go to the supermarket.” www.noaa.gov/about-our-ag...

🌿 Green Action Week 2025 🌿 This week, we’re embracing sustainability! In our department, members are swapping plants, sharing plant-based cakes, and discussing green ideas with our Green Team. 🌍💚 #GreenActionWeek #Sustainability #Environment #OxfordUniversity

Microsoft's own research confirms something that was already pretty obvious: relying on a text generating machine to come up with answers erodes critical thinking, and is a method favoured by those who never liked doing critical thinking in the first place advait.org/files/lee_20...

Anyone get a sense of irony from OpenAIs claim here? www.bbc.com/news/article...

I am thrilled to share our recent publication, "An off-lattice discrete model to characterise filamentous yeast colony morphology", which uses agent-based modelling and Bayesian inference to understand how yeast grows, is now available online in PLoS Computational Biology. doi.org/10.1371/jour...

Two talks at CERN today related to first results using simulation-based inference (likelihood-free inference) at the LHC. CMS (talk by Calandri): indico.cern.ch/event/138922... ATLAS (talk by Gosh): indico.cern.ch/event/1479992/ ATLAS paper: arxiv.org/abs/2412.01600

Thread on need to fight for evidence-based policy - a response to Trump's cabinet picks. Based on new @bmj.com article by me, @martinmckee.bsky.social & @kentbuse.bsky.social TLDR: Now is the time to stand up for science, not appease those in power attacking it www.bmj.com/content/387/... 1/14

I'm very happy to see papers like this. We need more contributions to the underlying theory. Similarly, we need more theory to understand pros and cons of density estimation based methods (posterior or likelihood) to ratio-based methods (likelihood ratios and posterior-to-evidence ratio)

Check out this #SMB #SocietyMathBio starter pack. This was the default Starter Pack set up on our feed, but we can add to this as well to help build the mathematical biology community on BlueSky. go.bsky.app/2sXtZV4

This video will break your heart if you care about nature. www.theguardian.com/environment/...

Nice starter pack of mathematical biologists by @joshuabull.bsky.social go.bsky.app/GVkxwBv

@rellypops.bsky.social dropping the wisdom - people often misunderstand self care, she says. "The self does not have to be selfish". Think about it as extended beyond you. Approach self care on the spirit of "what do I have to do for myself to be able to be there for others?"

The ✨ML Internship Feed✨ is here! @serge.belongie.com and I created this feed to compile internship opportunities in AI, ML, CV, NLP, and related areas. The feed is rule-based. Please help us improve the rules by sharing feedback 🧡 🔗 Link to the feed: bsky.app/profile/did:...

To celebrate the new beginnings on Bluesky, let's reminisce about one of our highlights from the old days: The unexpected shout-out by @fchollet.bsky.social that made everyone go crazy on the BayesFlow Slack server and led to a 15% increase in GitHub stars.

Utter anti-science bullshit from the Australian Financial Review. Next week - “Australia’s high-grade arsenic can improve your health.” https://www.afr.com/policy/energy-and-climate/how-australia-s-high-grade-coal-can-reduce-global-emissions-20210317-p57bof

Wonderful to see this paper out! It was a pleasure to work with David Frazier, @ryanpkelly.bsky.social and @chris-drovandi.bsky.social again!

When do you need to collect more data? ... surprisingly, more data often has little value for decisions. Our new paper unravels why "Value of Information Analyses" can yield surprising results in #ecology doi.org/10.1111/2041... w @katehelmstedt.bsky.social in @methodsinecoevol.bsky.social 🌍

exciting new seminar series on "Post-Bayes" organised by Jeremias Knoblauch (he is not in Bluesky yet)

Pretty excited by the recent uptick of science twitter migrating to blue sky. I haven’t been active here recently, but looking to change that!

The beta version of BayesFlow 2.0 is becoming more powerful and stable by the day. If you are curious about Amortized Bayesian Inference, give BayesFlow a try! github.com/bayesflow-or...

To those prepping 2026 Discovery Projects EOIs while still waiting on 2025 outcomes: I don't know when they'll be released. I'm sorry. Remember, ARC *planned* this. Planned outcomes for 20–29Nov & 13Dec EOI deadline. They knew ~500 teams would now be wasting time prepping EOIs.

TLDR the short term outlook for covid is relatively good compared with the last two summers: historically low levels, slow growth, and no notable variants on the horizon. Topping your immunity up with a vaccine is never a bad idea if you're eligible www.nzherald.co.nz/nz/covid-19-...

I created a starter pack for simulation-based inference (aka. likelihood-free inference). Let me know if you’d like me to add you. go.bsky.app/GVnJRoK

Thrilled to contribute to this work led by David Frazier providing theory for NPE/NLE in simulation-based inference. These methods are known to match the accuracy of ABC and BSL with fewer simulations, this paper rigorously shows why this can be achieved. arxiv.org/abs/2411.12068
