But is it really a strategy? Or is the entire foreign policy just based on ‘vibes’ from a person cult around delusional narcissistic guy who just incoherently rambles about whatever comes to his mind?

Calling hidden prompts for LLMs ‘bribery’ is overshoots the goal. If we want every paper to be “digestible” by an LLM, we “enable” LLM reviews. Then, there is an incentive to write (with meaningless changes or not) in a way that LLMs give favourable reviews to, instead of writing for humans.

Not sure if “bribing a reviewer” is the right comparison. Is it not literally more like asking for a good review?
josauder.bsky.social
But isn’t the real scientific misconduct reviewers who use LLMs for review? Of course hidden prompts in papers are questionable, but they don’t detract from the scientific results/progress like the opposing player (LLM reviews). Under normal circumstances, these prompts have no effect whatsoever

The return of Abrego-Garcia to face due process in the US, after Trump officials swore he would never ever return to the US, is a reminder that politics matters and pressure works.

Don’t give up. Don’t let the fascists relax.

For those in Switzerland (especially Zürich) - I strongly encourage you to go to the World Press Photo exhibition in the Landesmuseum.

Like every year, it's completely soul-crushing, but so important. I have so much admiration for these photographers.

Using the Coralscapes dataset, it becomes easy to transfer semantic information directly into 3D point clouds! Here's an example of a few images from a simple camera being used to make a semantic point cloud of an entire transect! #deeplearning #ai #coral #ai4conservation

Meta introduced Llama 4 models and added this section near the very bottom of the announcement 😬

“[LLMs] historically have leaned left when it comes to debated political and social topics.”

Addressing bias in LLMs

It's well-known that all leading LLMs have had issues with bias-specifically, they historically have leaned left when it comes to debated political and social topics. This is due to the types of training data available on the internet.

Our goal is to remove bias from our Al models and to make sure that Llama can understand and articulate both sides of a contentious issue. As part of this work, we're continuing to make Llama more responsive so that it answers questions, can respond to a variety of different viewpoints without passing judgment, and doesn't favor some views over others.

We have made improvements on these efforts with this release—Llama 4 performs significantly better than Llama 3 and is comparable to Grok: • Llama 4 refuses less on debated political and social topics overall (from 7% in Lama 3.3 to below 2%).
• Llama 4 is dramatically more balanced with which prompts it refuses to respond to (the proportion of unequal response refusals is now less than 1% on a set of debated topical questions).
• Our testing shows that Llama 4 responds with strong political lean at a rate comparable to Grok (and at half of the rate of Llama 3.3) on a contentious set of political or social topics. While we are making progress, we know we have more work to do and will continue to drive this rate further down.
We're proud of this progress to date and remain committed to our goal of eliminating overall bias in our models.

This has been a colossal effort from the team: data acquisition, 1500+ hours of expert annotation, and thorough benchmarking! 🤓

A big thank you to my co-authors @viktordo.bsky.social, Guilhem Banc-Prandi, Gabriela Perna, Anders Meibom, Devis Tuia, and all members and partners of the @trsc_org!

More details in the pre-print: arxiv.org/pdf/2503.20000

Coral reefs are under unprecedented threat, and monitoring is crucial to devising and assessing effective conservation strategies.

Automated coral surveys based on computer vision have potential to scale monitoring up!

Le monde reports that on March 9th a French scientist heading for a conference was denied entry to the US. His computer and cellphone were searched, and messages to friends were found where he expressed his opinion on the Trump admin and their politics wrt to science.

I know this is a half-joke and I’m taking the bait - but if Ukraine loses this war is it forced to surrender we enter a new era of barbarism and imperialism, where military expenditure will remain the number one issue for decades, and air purifiers will be way at the bottom of anyone’s priorities.
