andyxor··on Facebook Dangerous Individuals and Organizations List (Reproduced Snapshot)
You’re right I always mix them up, corrected
andyxor··on Facebook Dangerous Individuals and Organizations List (Reproduced Snapshot)
And how about the indigenous Inca & Maya people, nobody wants to see their human sacrifice culture celebrated on Facebook (Mel Gibson exposed the ugly truth in Apocalypto)

And the Spanish Inquisition, Bluebeard, Ivan The Terrible, Robespierre, Lenin, Beelzebub and Donald J. Trump?

The ban list is way too short.

andyxor··on Group effort to study the mathematical sciences for “saving the planet.”
Some believe humans should strive to become multi-planetary species, e.g. to avoid a possible extinction event.
andyxor··on Group effort to study the mathematical sciences for “saving the planet.”
Arguably, time is better spent studying nuclear engineering.

That's the only thing that can save the planet (besides enabling space exploration and colonization of Moon and Mars)

andyxor··on Ask HN: As a professional, does it worth it to learn the math behind NN?
there is not much math, don't let the academic papers razzle dazzle you, they make things look complicated to get their grants

in practice, as long as you've studied basic calculus and understand how to find a minimum of a function via derivative you're good, there is your "gradient descent" in a nutshell: https://www.mathsisfun.com/calculus/maxima-minima.html

everything else is plug-and-play from existing libraries

you can ask any "data scientist" or "ML engineer" what they do all day, it's a whole lot of copy paste, and tweaking the data and parameters through trial and error until it fits

Edit: Ok , it would also help to understand dimensionality reduction via PCA/SVD at least once, it's available in any linear algebra book: https://en.wikipedia.org/wiki/Singular_value_decomposition , https://en.wikipedia.org/wiki/Principal_component_analysis that's probably the best and most "scientific" part of ML

andyxor··on Neuroscientists roll out first comprehensive atlas of brain cells
If you want to understand how the brain works this is a good intro with some realistic neuronal network models ( spoiler: these have nothing to do with “artificial neural nets” as we know them) https://www.amazon.com/Brain-Computations-Edmund-T-Rolls/dp/...
andyxor··on Modern Crocodiles Are Evolving at a Rapid Rate
Soon they will start a popular startup incubator and change VC investing as we know it
andyxor··on Ask HN: How do you memorize things you read?
Ben Franklin did something similar, he copied books by hand I think
andyxor··on Megatron-Turing NLG 530B, the World’s Largest Generative Language Model
https://www.amazon.com/Brain-Computations-Edmund-T-Rolls/dp/...
andyxor··on Ask HN: A US programmer makes 3 times that of a EU programmer. Why?
we are just worth more
andyxor··on Peter Norvig Joins Stanford HAI
Big fan of your spellchecker
andyxor··on Reflecting on Four Years at Databricks
Databricks IPO is upcoming, with valuation of ~40B.

But I predict it will be sold to either Microsoft, Amazon or Salesforce within a year or so, may be sooner.

andyxor··on Megatron-Turing NLG 530B, the World’s Largest Generative Language Model
That’s correct understanding as of 1943 when the “artificial neural network“ model your professor is teaching was developed.

There is a whole lot of new knowledge on how live neurons and networks of neurons work that had been collected in the last 75 years in the neuroscience domain but it’s mostly ignored by computer scientists.

andyxor··on China blocks Wikimedia from entering World Intellectual Property Organization
I mean, most of Republicans on wikipedia are vilified as "far-right conspiracy theorists" and all shades of evil, with links to fake news as source of information (Washington Post for example)

one can argue, that if MSM spreads disinfo what can you expect from wikipedians, but the problem is their "power editors" and admins are a small clique with very particular political bias, it's just another echo chamber

andyxor··on China blocks Wikimedia from entering World Intellectual Property Organization
well pick any American politician right of center and check their wikipedia page.
andyxor··on China blocks Wikimedia from entering World Intellectual Property Organization
not a fan of China government but in this case I tend to believe them, I've seen Wikipedia volunteers spread actual disinformation in a concerted effort especially on politically charged topics.
andyxor··on Ask HN: What are we doing wrong?
because people should not be judged by the color of their skin but by the content of their character.

many still believe in that dream.

andyxor··on Ask HN: What are we doing wrong?
trying to silence people who think different.

corrective course: start by removing the "flag" button

andyxor··on [dead]
not encouraging delusions of mentally ill is not about “opposing their existence”, these people need help.

“Gender Dysphoria” is still considered a psychiatric disorder and (arguably) should be treated as such.

I think Chappelle’ jokes oppose the “celebration” of mental illness that somehow became the new normal recently, that one is not allowed to speak against.

andyxor··on Tesla Moved Its HQ to Texas Following Explicit Offer from CA Assemblywoman

andyxor··on Tesla’s headquarters will move to Austin
makes sense, especially after $137M court order over restroom graffiti
andyxor··on Hierarchical Navigable Small Worlds
thanks so much for writing this, unlike LSH there are very few articles on HNSW for some reason, while it's one of the most efficient (and relatively simple) nearest neighbors search methods out there. There is a precursor paper by HNSW author which explains the rationale and has interesting links to network science and neuroscience: https://arxiv.org/abs/1507.06529

I personally think both LSH and HNSW should be added to standard CS curriculum because of generality and so many immediate practical applications.

andyxor··on How to train large deep learning models as a startup
it's more like try different off-the-shelf models on some sample of data until the performance is somewhat acceptable

Unless you're Google, who even trains models from scratch these days, at most you do some fine-tuning

andyxor··on Facebook banned me for life because I help people use it less
as long as social media company stays in the news it's alive and kicking, no one talks about dying companies.

Time to buy more FB stock.

andyxor··on Americans' Trust in Media Dips to Second Lowest on Record
well, what do you expect if they lie about almost everything.

The "Fake news" phenomenon is very real.

andyxor··on California is shutting down its last nuclear plant
Nuclear is the only hope we have to fight climate change
andyxor··on Facebook is nearing a reputational point of no return
Facebook is awesome, what are they talking about
andyxor··on MIT Abandons Its Mission. and Me
It feels like mass delusion, where otherwise rational, educated, smart people really believe in this woke nonsense in an almost religious manner and would attack you , even physically, if you're to speak against it.

I hate to bring up Godwin's law yet again but i think that's what some people felt in Germany when it was descending to Nazi madness with mobs marching outside.
