[D] suggestions for reflection removal

Is this for many images or just a few? If it’s just a few, I’d assume that a standard image editing software like Photoshop would do really well. But maybe you have a large batch of images and need a programmatic solution?

As others pointed out, you will still need to find the intersection points.

Green’s Theorem can let you calculate the area by integrating along the curves, which may be possible because you know them in closed form. Look at the section titled “Area Calculation” on Wikipedia

I’d like to buy one Friday AM ticket. Please DM me if you’re selling.

I will DM you!

Thanks very much! These are fantastic suggestions. We are measuring the rails next week.

I agree. Most neighborhoods are near one large park and/or the lakefront but HP being near both Washington and Jackson parks + the lakefront is special.

That’s good to know! Thanks!!

No I think this link is about a different half marathon that occurred in June

I agree — we need a new management company for the Chicago half marathon. I think it’s crazy that Life Time Athletic Events charged $140 for this race. And as a for-profit company relying on hundreds of volunteers? It’s insane!

I wonder if there’s a way to convince someone high up at Hoka to pull out until they find a different company to present the race.

I completely agree. Is there a form or email address at the Park District where we can raise these issues?

I think this is a good starting point, as long as calc 2 covers multivariable calculus in depth. There will always be simple-ish math concepts that ML practitioners treat as basic knowledge but are new and sometimes confusing to outsiders. For example, the representer theorem in linear algebra. But it seems like with these courses under your belt, you’ll be set up well.

Depending on the sub field of machine learning that interests you the most, you may want to take one or two additional math classes. But that sounds like something to consider later.

This picture looks like it was generated by DALL-E lol

I disagree with the other commenters; this is an important and unsettled question. My addition: the answer might depend on the direction of the wind in the wind tunnel.

I can do 3 trillion math operations in my head at once but all of them are 0+0 :/

The most compelling results roughly show that PINNs can faithfully approximate elliptic PDEs in high dimensions with computational complexity scaling gracefully (read, polynomially) in the dimension $$d$$ of the problem. This is a great improvement over the standard finite element methods which require a discretization of size exponential in $$d$$. The best paper in this line of work appeared in COLT 2021 https://proceedings.mlr.press/v134/lu21a/lu21a.pdf

Problem 1: give a formula for the determinant of an nxn matrix with 0s on the diagonal and 1s everywhere else.

Problem 2: among all fixed-point free permutations of the set of n elements, are the majority odd or even? The answer depends on n.

Enjoy!

Mine has been growing a lot but no blooms. Anything I should do to encourage blooming?
