@2b93618c We have male cardinals, in particular, get aggressive in the spring and throw themselves against windows. I too thought my dog had secret skills for bird catching ... until I went out first in the morning and there are birds on the deck from window strikes.
Today's reading:
Optimal Whitening and Decorrelation.
Agnan Kessy, Alex Lewin, and Korbinian Strimmer.
tl;dr: Covers ‘whitening’, linear transforms that convert random vectors to another random vector, where the new random vector has covariance equal to the identity matrix. ZCA whitening is used in paper ‘CamP: Camera Preconditioning for Neural Radiance Fields’, Park et al. 2023.

@0609a068 Have you seen the #lichenSubscribe hashtag?
1 -- it took me a LONG time to get the joke
and
2 -- I feel like your photos fit with that hashtag.
Two nurses were here to administer my medication* and one nurse says, "I need some Wite-out™️" and the other nurse says, "oh, I have some here". And she had 3 wite-out pens. Amazing, I haven't used that stuff in 20 years (or more), but it seems to be part of the toolkit in nursing.
*through a home health service instead of the hospital. This has been awesome.
@c4e61add 👀 I have been obsessed with preconditioning for a couple years, I'll have a look at your thesis!
(There's a sketch of a paper there.)
Good info or what is At the top of mind for me,I'm considering a blog post.
I've been reading about preconditioning for a while, and recently, whitening (related, sphering, these names ??!).
There seems to be general confusion about these terms. Also --standardization and normalization. Sort of a mess.
@d081ac8d
I've had this for 13 years and just now felt I could do this w/o getting overwhelmed.
Also, my specialist is a research guy, which has really helped to get a sense of the known, unknown, 🤷♀️ topics.
