These were the results. I think it's interesting to see that most of the variance (55.6%) is explained by the first principal component. How would you interpret these 2 principal components?
#pca

A lot of papers talk about tuning #autoencoder bottlenecks. Is there some autoencoder-like technique that share's #PCA's property of putting the most relevant information in the first element, second most in the second, etc?

Neat!

"This post is my first attempt to develop an analogy that connects least squares methods, like regression or PCA, to physical intuition about springs or elastics."

I'm told I should make an #Introduction and that hashtags are back in style, but I don't know what I'll be posting about here so no promises on anything 🙂 Mostly here to keep up with friends.

I enjoy #Reading, #IndieGames, #GuildWars2, and so much more I don't always have time for. I'm a #Christian member of a #PCA church trying her best as an #Introvert to stay involved. Also am an #Enneagram9 so I try to keep things chill, though I make no apologies for any #Puns that cross your feed 😉

How does Chuck Norris know how many Principal Components to use?

By using the elbow method. Quickly followed by a sharp uppercut method.
