From the reddit post (https://www.reddit.com/r/math/comments/k3ia4q/eigen_grandito_principal_components_analysis_of/): Recently I took a deep dive into the SVD/PCA. My goal was to understand the math with confidence, and then use it for something interesting. In my project, NumPy's svd function does the hard work, but even still, just using it challenged my understanding in instructive ways. Between my study and the project, I feel I truly understand, mathematically, what the SVD does and why it works. Finally. Feels good. Anyway, my project was to calculate the Eigen Grandito, which is named after the Onion article, "Taco Bell's Five Ingredients Combined In Totally New Way", which, in more mathematical terms, asserts that Taco Bell's dishes are all linear combinations of the same ingredients. And so the Eigen Grandito "recipe" is just the first principle component of the matrix of Taco Bell dishes and their ingredients. In theory, the Eign Grandito is the "most Taco Bell" of Taco Bell dishes. Here is a link to my code and the results: http://www.limerent.com/projects/2020_11_EigenGrandito/ Any feedback and corrections are welcome. I would love to know if I've made any mistakes. Finally, here are the results: 6.5 in flour tortilla - 1.0 10 in flour tortilla - 0.6 12 in flour tortilla - 0.3 taco shell - 0.6 taco shell bowl - 0.1 tostado shell - 0.2 mexican pizza shell - 0.1 flatbread shell - 0.2 seasoned beef scoops 2.0 chicken scoops 0.4 steak scoops 0.4 chunky beans (rs) red scoops 1.0 chunky beans (gs) green scoops 0.3 seasoned rice yellow scoops 0.4 lettuce (fngr) fingers 3.7 lettuce (oz) ounces 0.4 diced tomatoes fingers 3.1 diced onions fingers 0.2 cheddar cheese (fngr) fingers 2.2 three cheese blend (fngr) fingers 0.3 three cheese blend (oz) ounces 0.2 nacho cheese sauce pumps 0.6 pepper jack sauce z 0.2 avocado ranch z 0.2 lava sauce z 0.3 red sauce pumps 0.4 sour cream (clk) clicks 1.4 sour cream (dlp) dollops 0.3 guacamole (dlp) dollops 0.2 red strips fingers 0.2 fiesta salsa purple scoops 0.1 nacho chips - 0.2 eggs scoops 0.1 I have no idea how to actually prepare this. I guess you just grill it.
