#nmf — Public Fediverse posts

I added several figures (3-6 through 3-9) to Part 3 of my unmixing posts, to better illustrate the performance of consensus interpretation methods.

The third and last of the series on unmixing using NMF is now posted at

https://dblog.vitumbre.tech/dart/unmixing-using-nmf-part-3-assessing-accuracy-of-end-members/

Part 3 illustrates the variability of results that can occur when repeatedly unmixing the same data set, and presents approaches to addressing the resultant uncertainty.

Part 2 of this series on unmixing is now available:

https://dblog.vitumbre.tech/dart/unmixing-using-nmf-part-2-evaluating-the-number-of-end-members/

Part 2 addresses the challenge of deciding how many end members are in a data set, recommends algorithms for Python, Julia, and R, and illustrates how several factors affect that determination.

I just posted part 1 of a 3-part series on unmixing of data sets using non-negative matrix factorization.

https://dblog.vitumbre.tech/dart/unmixing-using-non-negative-matrix-factorization-nmf-part-1-introduction-and-implementation/

Part 1 contains implementations in Python, Julia, and R, and includes an assessment of the relative accuracy of these implementations.

Parts 2 and 3 will follow shortly, and will contain more detail on the identification of, and accurate characterization of, unmixing end members.

While going over the methods, I noticed they used #NMF where #PCA is mostly used. And while refreshing ;) my knowledge of the differences between the two, I stumbled upon a simple question/answer on #CrossValidated: https://stats.stackexchange.com/questions/502072/what-is-the-main-difference-between-pca-and-nmf-and-why-to-choose-one-rather-tha

This links to a book from #TrevorHastie, offered for free on his website: https://hastie.su.domains/publications.html

Another reason to finally have a look at "An Introduction to #Statistical Learning with Applications in R (second edition)" by James, Witten, et al.

I was confident Bullock was going to make that FG. Honestly, I didn’t cheer after the FG.. I was so relieved we won that I just let out a heavy exhale. 😮‍💨

The new Pupil Slicer album is pretty good https://album.link/i/1663102096 #metal #NowPlaying #nmf

Some great new releases this #NewMusicFriday!

• Panchiko released their first true full-length, “Failed At Math(s)”. https://panchiko.bandcamp.com/album/failed-at-math-s

• Glare released a remastered set of their first 2 EPs, titled “Into You / Void In Blue”. I’d never heard these before. It’s some excellent #shoegaze. https://glaretx.bandcamp.com/album/into-you-void-in-blue

• Clearbody announced a new EP titled “Bend Into a Blur” releasing in June, and dropped the first single. https://clearbody.bandcamp.com/album/bend-into-a-blur

• "Extreme-sensation-1" by eSs (a.k.a. Scuba) (https://scubaofficial.bandcamp.com/album/extreme-sensation-1)

Anything new on your radar on this #NewMusicFriday? #NMF

Not much for new music today 😞

- Mac DeMarco released his instrumental album "Five Easy Hot Dogs". Sadly, it's kinda boring. https://album.link/i/1661489563
- I was hopeful for A$AP Rocky's new single "Same Problems?", but… it's also kinda boring. https://song.link/i/1663367057

It's been a pretty dry month so far! I suppose that shouldn't be too surprising, people are just starting the year out. I know of at least 2 records out in February that I'm excited for though. 🤞

#nmf #NewMusicFriday #NowPlaying

Two new albums I’ve been looking forward to released today.

Hardy : the mockingbird & THE CROW

Maneskin: RUSH!
