One good source might be NIST. Here’s an open access ballistics dataset: https://www.nist.gov/programs-projects/nist-ballistics-toolm... Edit: I should have looked at the linked book first, since this dataset is listed

I’m kind of tacking this on here, but does anyone have a good recommendation for notes or a book on applied topology for someone with a decent but not extensive background in applied math? In particular, my goal is to more deeply understand

There are a lot of unhelpfully named metrics, algorithms, etc. but I actually think “edit distance” is fairly illustrative as these things go. Another good one is Manhattan distance (or better yet, city block distance) in place of Hamming d

One interesting observation: there’s a noticeable gap between average sentiment on Fri/Sat vs. Mon/Tue/Wed (especially when viewing the “Full” trend). Fridays rule—it’s science. I wonder what accounts for the trough between ~

If “the emojis are of bad quality” is what constitutes an ugly and unpleasant working environment in 2019, I’d say the future is looking bright indeed.

Unfortunately, this is not so. The John Muir Trail has seen extremely rapid growth [1] in the number of thru-hikers (many of whom are first-time backpackers). It’s the same story for other popular “named” trails that become bucket-list item

Take a look at “Neural Networks: A Systematic Introduction” by Raul Rojas: https://page.mi.fu-berlin.de/rojas/neural/ It’s an older book, but it’s a deep dive into the math and intuition of neural networks. We use

I think it’s actually both important and possible to differentiate between stats and ML (and AI for that matter). Statisticians, ML engineers, and data scientists all have related but distinct skill sets, knowledge, methodological experienc

Reflecting on ancient civilizations is always exhilarating—a way to connect with where we’ve been as a species, and where we may eventually go. I wonder how life must have felt subjectively from the perspective of someone without the lenses

Oh yeah, and use tools like WolframAlpha to check your work and explore problems in more depth (like visualizing functions, seeing alternate forms). Get the app and use the solution explainer thing—essential for e.g. solving integrals. It m
