New short paper forthcoming in Statistics & Probability Letters:

An objective non-local prior for skew-symmetric models.

arxiv.org/abs/2603.08285

This paper develops a Moment-Objective Minimum-Discrepancy (MOOMIN) Prior for testing symmetry against skew-symmetric alternatives.

Learning Functions of Halfspaces We give an algorithm that learns arbitrary Boolean functions of $k$ arbitrary halfspaces over $\mathbb{R}^n$, in the challenging distribution-free Probably Approximately Correct (PAC) learning model, ...

Well, this seems like a big deal. arxiv.org/abs/2603.087...

"This is the first algorithm that can PAC learn even intersections of two halfspaces in time 2^o(n)."

Didn't know that this one had a name, but it's a cute one. There's a nice "polynomial-style" proof (cf. SoS hierarchies etc.), a nice "martingale-style" proof, and probably some others too. Neat!

I don't really understand why the statement requires numbers a_1 ... a_n ? The proof seems to be valid for any rv A in the interval [m,M] right? Am I missing something?

Two more #birds from Vietnam: pink-necked green pigeon, and white-shouldered starling. The photo of the starling does not make justice to its elegance... But you can still see its beautiful blue eyes!

Back to Singapore tonight...

In each new paper, I cite *all* my papers cited a number of times smaller than my h-index. I also bully other researchers until they do the same thing.

The good news is that Hivebrite will use AI to create your platform. So, instead of hiring people to write code, they will have 15k to do something fun with. You should be happy for them ๐Ÿ˜…

Skore Is Live: Track Your Data Science Skore by Probabl: The collaboration platform for data scientists. Evaluate models, automate reports, and bridge the gap from notebooks to production.

At probabl, we're focused on improving the data-science stack.

We just made public the skore platform, augmenting the open-source library.
Our dream is that, with skore, a data scientist will not feel overwhelmed by the iterative process of data science, but empowered
