he published the Weierstrass Approximation Theorem at age 70. Weierstrass did not earn a doctorate and, did not have a university position until age 41. John Wallis also continued to produce and write significant mathematics into his 80s.

Today I learned that Weierstrass is one counterexample to the widely held belief that mathematics is exclusively an enterprise for the young. He did significant mathematical research well into his 60s and 70s,

It looks so fancy..

@dgleich.bsky.social Was wondering if this is a good method, and if someone did something similar before..

😄😄

2. To scatter smart points into the box, look at how f rises or falls across the space. Fit a best hyperplane to this behavior. Then ask which coordinates tilted the plane the most — that tells me which variables control the function.

1. Oh, great! 😄

I was thinking about sketching a cheap method to detect approximate active subspaces in BB functions that are defined on n-cubes, thought about this:

I am trying to learn about approximate active subspaces identification in a blackbox function, f:[a,b]^n\subset R^n \to R, where n is big. In this context, I think of the active subspace as the few special directions through the input box along which small nudges make f change the most, on average.

Thank you! I will put the magic spells for reference, hahah :D

Haha! Thats so cool. I am sure "in any event" and "in particular" are in this list. 😄😄

During my last presentation, I used the phrase "in any event" 20 times or so from watching your lectures. This is a cool phrase, I will use it from now on. Hahaha :D

2. For this specific situation, I'd also pin the photos of the students alongside the poster (if the poster display board allows), with a note explaining why they couldn't attend, which helps personalize the experience, catch more eyes and adds context for the audience. :D

1. In my experience, eye-catching visuals and a compelling title are key to attracting attention to a poster. Once someone is drawn in, I greet them with a smile and offer a concise, 5-minute overview of the work, trying to make sure I explain things in an intuitive and engaging way.

P.S. I'm not an organizer; I am simply sharing this opportunity.
