Orca mom carries dead newborn calf in San Juans

It is not the first time such on-the-nose grief has been observed in this endangered population. In January, orca J35 carried a dead baby for at least five days. J35 had previously made world headlines in 2018 when she carried her dead calf for 17 days and 1,000 miles. From @kuow.org

β€˜World Models,’ an Old Idea in AI, Mount a Comeback | Quanta Magazine You’re carrying around in your head a model of how the world works. Will AI systems need to do the same?

"World models," internal AI simulations of reality, are again at the forefront of AI research. While today's LLMs use a fragile patchwork of heuristics, developing true world models is seen as essential for creating robust and adaptable intelligence. #MLSky

Mathematical Beauty, Truth and Proof in the Age of AI | Quanta Magazine Mathematicians have started to prepare for a profound shift in what it means to do mathematics.

A new paradigm in math is coming. AI will push it toward a form of neointuitionism and hermeneutic practice, where proofs and math objects are sampled from a system, whether social or artificial, and then interpreted by humans (as in social sciences).

Mathematical Thinking Isn’t What You Think It Is | Quanta Magazine The mathematician David Bessis claims that everyone is capable of, and can benefit greatly from, mathematical thinking.

Many people, especially those untrained, truly believe doing math is just about following strict rules to manipulate symbols on paper. It's more about imagining, playing a naΓ―ve for the obvious, and breaking the rules along the way.

I think one misconception about CI is that is about theory-building. It’s not. It’s about the logical tools to deduce hypothetical changes on already built world-models/theories. Neither CI nor the used models/theories (as in physics) imply the laws of nature.

Karl Pearson was a ferviente opponent of causal language because it invites metaphysics into science. Similar criticism of β€œsubjectivity” have faced Quantum Mechanics and Bayesian Statistics. More than objectivity, utility should be valued

Internally valid RCTs are relevant, even essential, for scientific discovery. When externally valid, they provide valuable insights for policy design targeting reference populations. Science is not only about discovery: it’s also about world-model building, testing and explaining

I already advertised for this document when I posted it on arXiv, and later when it was published.

This week, with the agreement of the publisher, I uploaded the published version on arXiv.

Less typos, more references and additional sections including PAC-Bayes Bernstein.
