How do we select the best lambda for sparse PCA?

We can't compare cross-validated errors since there's no error to speak of. Do we look for cumulative variance explained? Is there a package that can help us pick the best lambda?

Humectants masterlist (products I have tried + subreddit recs!)

hellooo! hope your 2022 is going as smoothly as the skin you desire lmao. we'll get there someday! (or if you already have, congrats!) . anyway , this is a list of all the humectants that I have tried. some worked great, some were a waste of money and some were mediocre. I will be rating them for convenience and will also be mentioning the price .

what is a humectant ?

water-loving ingredients that draw moisture into the stratum corneum, the top layer of skin, whether through the environment or through the deeper layer of skin (the dermis) (net se hai πŸ€‘πŸ‘Œ)

the list is divided into cleansers, toners ,serums, gels , moisturizers , creams , essence , emulsions for face. making one for body related products might a bit difficult but ill see!

list of commonly used humectants in skincare :

  • hyaluronic acid (and types)
  • snail mucin
  • lactic acid
  • aloe vera
  • honey (propolis)
  • glycerin
  • propylene glycol (or propanediol)
  • butylene glycol
  • panthenol

skin info : F17

type : dry/combination (earlier was oily combination, so the list has a combo of products) , acne-prone, have pit scars and acne marks and scars ( *insert dark kermit meme*: scratch them pimples) blackheads and sebaceous filaments .

weather : dry winter ( Delhi 🀑) and humid summers.

here we gooo! (*cue mario music*)

cleansers

Simple Kind To Skin Refreshing Facial Wash

Mrp : Rs. 375 (bought at Rs. 319) for 150ml from nykka

humectant : panthenol, propylene glycol and pantolactone

for skin type : all! dry, sensitive, combo , acne prone and oily

texture and appearance : jelly-like , clear looking , smooth gel . lathers easily. unscented

used this when I damaged my barrier 🀑 takes off excess oil without stripping and leaves skin soft and hydrated . extremally gentle . no dry or stretchy feeling left after (signs of dehydration ) more suited for dry and sensitive skin but works on all types! little hard to wash off if used in large amount , so pea size is enough!

status : still in use.

rating : 5/5 and WRP

It's Skin Snail Blanc Brightening Cleansing Foam

Mrp: Rs. 490 for 100ml from nykka

humectant : snail mucin (21% as it claims)

for skin types : oily skin

texture and appearance : thick, white and creamy (get your head outta the gutter), kind of like a ponds cleanser. lathers into marshmallow fluff. citrus scented

hard no 🀑. extremely drying and stripping. wouldn't even recommend

The Origin of the Uyghurs of Central Asia: Where did their Indo-European ancestry come from?

The Uyghurs are an interesting people. They straddle two worlds. East and West. But who are they? And for how long have they existed where they are?

https://preview.redd.it/8f1206f4se281.jpg?width=478&format=pjpg&auto=webp&s=8dfca82b9637d89a45c968f98148c68b718f8d36

>The Uyghurs have traditionally inhabited a series of oases scattered across the Taklamakan Desert within the Tarim Basin. These oases have historically existed as independent states or were controlled by many civilizations including China, the Mongols, the Tibetans and various Turkic polities. The Uyghurs gradually started to become Islamized in the 10th century and most Uyghurs identified as Muslims by the 16th century. Islam has since played an important role in Uyghur culture and identity.
>
>An estimated 80% of Xinjiang's Uyghurs still live in the Tarim Basin.[29] The rest of Xinjiang's Uyghurs mostly live in Ürümqi, the capital city of Xinjiang UAR, which is located in the historical region of Dzungaria.

https://en.wikipedia.org/wiki/Uyghurs

Did they maybe derive from the Ancient North Eurasians who left their mummies in the Tarim basin?

Was it later steppe peoples or the Tocharians?

Its no doubt that Turkic ancestry is majorly significant in their ethnogenesis but DNA research has pointed to older, more western European ancestry deep in their history.

I stumbled upon some interesting papers. One of them has calculated the dates in which the admixture occurred.

Genetic Landscape of Eurasia and β€œAdmixture” in Uyghurs

Bioinformatics of reddit, could you recommend me something to cluster/classify brain scans images?

Good evening fellow bioinformatics bioinformaticians** / computer biologists!

I've been offered an opportunity to study brain scans in order to help differentiate some diseases/states for an research team. The problem its im mostly a bioestatician that deals with multivariate data, and i dont have much experience dealing with image analysis (Although i just have used python and Keras to make a classifier about cats and dogs :D, and im doing my research on what can i learn about the topic)

Do you have any suggestions so i can tackle this fantastic opportunity?

Also, does anyone know how can i translate row/column analyses/approaches like pca, hieralchical clustering and that, to matrixes? Because, as far as i understand, i could translate an image to a data.matrix that has values per pixel, but then i would be dealing with matrixes like entries instead of rows as entries... and i cant fathom how could apply the traditional analyses that i already use like a hieralchical clustering.

** Sorry, second language, i keep messing this word up :C. Sadly i cant edit the tittle now.

Dropped my best ever dad joke & no one was around to hear it

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies πŸ˜‚

These aren't dad jokes...

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.

I did it, I finally did it. After 4 years and 92 days I went from being a father, to a dad.

This morning, my 4 year old daughter.

Daughter: I'm hungry

Me: nerves building, smile widening

Me: Hi hungry, I'm dad.

She had no idea what was going on but I finally did it.

Thank you all for listening.
