reader5000··on 2023 ACM Turing Prize awarded to Avi Wigderson
I think his argument assumes the existence of pseudorandom generators which map a small amount of "true" random bits to a large amount of bits that look random to any polytime observer. The "derandomization" is that we just have to check all possible states of the seed bits which hopefully will be logarithmic in the size of the problem so you can do exhaustive checking.
reader5000··on Persistent interaction patterns across social media platforms and over time
Mainstream corporate media is at least an order of magnitude more toxic than anything on the internet.
reader5000··on Ask HN: Why can't image generation models spell?
My intuition would be that both text and fingers are high frequency parts of the image and most image patches across most images don't have that amount of frequency. Text and fingers are relatively rare in images compared to e.g. clouds and textures on surfaces. Because of the rareness and difficulty of text image patches the models just don't dedicate that many parameters to it.

This could be entirely wrong however.

It would be interesting what would happen on a dataset with nothing but text.

reader5000··on ArXiv Papers as Audiobooks
Visual reading of dense papers also leads to failing to understand concepts or distractions.
reader5000··on Porn Sites Need Age-Verification Systems in Texas, Court Rules
Theres all sorts of statistics about the increasing amount of men that are virgins into their 20s and beyond, declining marriage rates, declining birth rates, "inceldom" etc. etc.

Its certainly plausible that at least for some subset of people becoming porn addicts when they enter puberty is disrupting their ability to form relationships as an adult.

Having said that its not really clear censorship is the answer. Probably over time phenotypes overly sensitive to porn addiction will just go extinct.

reader5000··on Google to pause Gemini image generation of people after issues
How is "stereotype" different from "statistical reality"? How does Google get to decide that its training dataset -"the entire internet" - does not fit the statistical distribution over phenotypic features that its own racist ideological commitments require?
reader5000··on Linear Algebra Done Right – 4th Edition
I think in the modern era a very good piece of advice, particularly for those of us without gorilla-like stamina to comb through a math text, is to go on your favorite video website and watch through multiple videos on the topic.
reader5000··on So far, AI is a money pit that isn't paying off
I'm not sure why they don't charge per usage.
reader5000··on A New Mode of Cancer Treatment
> I think one missing step is to fuse training and inference regime into one, just as in animals

It's not clear it is one. Sleep is training (replay from hippocampus). Wake is inference.

reader5000··on Regular use of Vitamin D supplement is associated with fewer melanoma cases
People who avoid the sun are less likely to care about health overall and therefore less likely to take vitD supplements?
reader5000··on What we know about LLMs
I think 8 months is a little short for the utility of a new tech to be fully realized and utilized. I'm pretty sure there were still horses on the roads long after 8 months after the Model T first went on sale.
reader5000··on OpenAI starts testing ChatGPT premium
The ai censorship is of the modern "social justice" form, which does not find roots in "waspy Protestants".
reader5000··on How songwriters felt watching the new Beatles documentary
I've somewhat had this phenomenon, with the added observation that if I listen to the recording multiple times it will "click" and will sound good again. Then I wonder if it actually sounds good or what.

reader5000··on GPT-3 and Scaling Trends
Recurrent neural nets is the general term for nets with memory as you describe. Indeed LSTMs, a type of recurrent net, used to be state of the art on language tasks until the GPT transformer models. I'm sure somebody somewhere is working to make a transformer with recurrency. The neural turing machine mentioned in another comment is such an example but it seems to have been abandoned.

The main problem with recurrent models is its hard to train them with backprop. For example the GPT-3 can handle sequences up to ~2000 tokens? I'm not sure what the largest sequence LSTMs could be trained on but it was probably less.

reader5000··on Why do companies with unbounded resources still have terrible moderation?
Reading this made me realize that the internet needs to be decentralized as soon as possible.
reader5000··on YouTube shuts down music companies’ use of manual copyright claims
It's a gray area because "hate speech" isn't a valid concept. 1A already excepts for inciting violence but that's not what radicalized censorship-extremists mean when they use the term. They specifically mean anything that is not canon to their current worldview.
reader5000··on YouTube shuts down music companies’ use of manual copyright claims
Does anybody have a definition of "hate speech" other than "points of view that I disagree with"? And if your definition is going to be something like "encouraging harm against groups of people" can you then point me to a single quote from a "hate speech" site demonstrating this?
reader5000··on Study finds Reddit’s ban of its most toxic subreddits worked (2017)
Free speech improves the human condition. Therefore, by your own argument, the authorities have the moral obligation to forcibly censor your own anti-free speech comments.
reader5000··on Study finds Reddit’s ban of its most toxic subreddits worked (2017)
Inasmuch as different parts of society disagree on how to "improve" it, one part does not have the right to censor the other.
reader5000··on Study finds Reddit’s ban of its most toxic subreddits worked (2017)
Burning a book is physical violence. Banning a sub is physical violence. In censorship you are forcibly destroying a communication between two nonviolent third parties.

> evidence indicated that rationality and clear arguments weren't winning

On what grounds do you base your own sense of "rationality and clear argument" as superior to that of the apparent majority of people that you refer to as "the cesspool"?

Whoever is in power determines what is "ethical society" or what makes society "better". Censorship is a form of physically violent oppression and is never justifiable.

Do what exactly?
reader5000··on Dynamic Programming for Technical Interviews
Yeah I thought the recursion+memo wasn't actually "dp" until I looked it up. Recursion without the memo is not DP however since you hit exp running time/memory and the whole point of DP is to avoid this.
reader5000··on Dynamic Programming for Technical Interviews
In "Algorithms" [Dasgupta, Papamdimitriou, Vazirani] they state that the memoization (e.g. querying a hash table) can have significant overhead leading to a large constant factor in the big O analysis. On the other hand, the bottom up approach using a table solves all the possible subproblems including ones that are not needed and ones that the recursive approach would avoid. So from a big O perspective the recursive top-down and the table bottom-up approaches are the same but there can be significant constant factor differences.
reader5000··on Dynamic Programming for Technical Interviews
Recursion with memoization can still take exponential time whereas a DP solution is usually going to be quadratic or better.

Ok but this isn't censorship related.
reader5000··on Amazon Pulls Books That Promote Unscientific Autism ‘Cures’
Thats fine but I get to decide if I want to buy a book about drinking bleach to cure autism, Amazon doesn't decide it for me.

They could not refuse business based on race in the US.
