Junior fag here. I feel like a complete brainlet for not knowing what an error function is. Explain it to me in terms i can understand

is basically a function that gives you how much losses you got or to put it simply how wrong your model is given data to be trained with

Its just a way of knowing how much your data is away from the actual value, or in other terms, how good your data is in terms of reputability

every living thing has an error inside of it that lets it function anywhere and become anything, it is the seed of the devil, and of god, that comes out over time to ensure the superiority of the species.

The Folk/Daniels research team has been working on a breakthrough discovery for multiple sclerosis. The Seattle based research group has found a link between the debilitating disease and unhealthy red blood cell production. They have discovered that iron deficiency and elevated oxygen saturation may be major contributing factors in the cause of the disease.

just use a solar panel and make a hydrogen bomb, once filled, explode. Could be a tv show. Die hydrogen but not hard bc bruce is old.

"How to draw" from Scott Robertson, who is an industrial designer / vehicle concept artist, should cover almost everything.
Make sure to follow the exercises.

Writing on public park grass fields? Anonymous 21/12/30(Thu)11:37 No. 17991 ID: 706068 [Reply]

What is the best way to write on a public park grass field? (I'm not thinking about proper lawns nor meadows for grazing.)

Methods that I won't even consider is plant-killer chemicals, burning or even cutting the grass. So what's left is planting flowers and/or fertilizing the field.

So what's the best seeds, fertilizer and deliver method?

I think people have done similar shit with moss. I have no idea how you would go about growing moss as they don't even have seeds.

And moss grows slowly and only on lichens. But maybe some kind of fertilizer and seed mix? I want the seeds to sprout so quick that birds doesn't have time to eat them.

So, I have a question regarding physics and mathematics. Between the two, which would give me more "smart sounding shit." I don't mean learning it to brag, I mean stuff like pure mathematics sounding totally abstract to normal people. I just want to be in a different world basically. Kind of like induced autism? Or like a constant high but without drugs. Pic unrelated

Physics on account of exotic entities like black holes. Astrophysics is known as an exotic hard science, as is Cosmology. They just sound cool on the lonesome there of. Nuclear Physics and Particle Physics and Chemical Physics and Subatomic Physics just sound cool also. Muons, gluons, quarks, and the like also sound good. I do not know why, probably because I know more about it, but I believe Physics has more pizzazz than mathematics.

Why not get into time travel? The good thing is the subject is an iceberg, on the surface it looks like a small subject but the majority is underneath.

Not only will you look autistic but everyone else will feel retarded. Double-win!

Theoretical mathematics is just people jerking off to fictional concepts that they made up on their own;
instead of trying to understand reality, they instead make classifications of abnormal phenomenons and then call it concept A and then just call it a day. Sure, it sounds smart but it's ultimately just retarded.

Physics is less so because there are actual practical elements in said field. But the theoretical mathematics syndrome is slowly creeping into the field so it's becoming another retarded field.

Which is why more people are more into engineering than just pure physics these days. Even though the latter was much more interesting.

Thanks to Harvard we are now allowed to talk about how certain people from India will fire you because you are not in their caste. Look at your company org chart and you will mostly see managers from india only seem to hire other people from india that are in their caste. There are some smart people from India but this racist behavior has to go. tps://www.nbcnews.com/news/asian-america/harvard-adds-caste-bias-protections-graduate-student-workers-rcna7279

Self-contradiction. It was about dalits.

You can be both smart and a castist.

Just as Cantor's theorem shows there is no set of all sets, there is also no set containing all truths.

Or to put it another way: it's a truth that all truths can't be collected up into a totality.

No wait, I might have misspoken my second part:
https://ncatlab.org/nlab/show/predicative+topos

That being said, I still stand by my point that I wouldn't want to work in any set theory without a set of functions between any two sets.

I don't buy this argument
consider a finite set {1,2}
then 1 is in {1} {1,2} and not in {2} {null}
and 2 is in {2} {1,2} and not in {1} {null}
The powersets are generated by the elements of the set.
This is like saying that there is no vector space basis of primes (2,0...)x1+(0,3,...)x2+(0,0,5,...)x3+... = v = (2,3,5,7,...)
