chychiu··on DAPO: An Open-source RL System from ByteDance Seed and Tsinghua AIR
Not sure why this is linked. The field has kind of moved on from DAPO
chychiu··on A $21B 'Kids in Chips' Startup Is Scooping Up Nvidia Talent

chychiu··on Co-evolution of self-replication and function in a digital primordial soup
Super cool work! What's next? Do you think with longer memory limits more interesting programs might emerge? Or is it substrate dependent?
chychiu··on Show HN: Claudoro, Pomodoro timer embedded in the Claude Code statusline
Your website is broken btw - Clicking into another article through related work goes to the same page
chychiu··on Simulating Cells Fighting to the Death
Pretty cool! Simulating artificial cells and observing their complex emergent dynamics has been an interest of mine On a similar vein, have you seen this before? https://github.com/chrxh/alien
chychiu··on There is no you in your brain – your identity is a "society of the mind"
If you mean this in a psychedelic context, my theory is the temporary dissolution of this “society” in recognising the “self” as “self”
chychiu··on EsoLang-Bench: Evaluating Genuine Reasoning in LLMs via Esoteric Languages
Considering that brainfuck only has 8 characters and models are scoring at 6.2% I don't think tokenization is the issue
chychiu··on Researchers develop a camera that can focus on different distances at once
I think the product was just too early for its time, and there is not much demand for it. For what it's worth, the founder (Ren Ng) went back to academia, and was highly instrumental in computer vision research, e.g. being the PI on the paper for NeRF: (https://dl.acm.org/doi/abs/10.1145/3503250)
chychiu··on MIT Study Finds AI Use Reprograms the Brain, Leading to Cognitive Decline
Was going to comment the same but you beat me to it!

On that note, reading the ChatGPT-esque summary in the linked article gave me more brain damage than any AI I've used so far

chychiu··on VC-backed company just killed my EU trademark for a small OSS project
I am sorry to hear that OP, I hope you fight the good fight and wish you all the best.

On a different note, a quick cursory glance of this company really makes me wonder who even gave them $160M? The company site is soulless and filled with corporate jargon, and the whole company smells of bloat and leadership team is a long list of people in bullshit jobs. Is this where VC money goes these days? I am dumbfounded by the degree of mismatch between capital and utility

chychiu··on EHRs: The hidden distraction in your doctor's office
I work in building software as medical device. Can confirm it’s still a quagmire
chychiu··on A.I. researchers are negotiating $250M pay packages
Actually that is decent data and reflective of current SOTA in terms of cost performance tradeoff
chychiu··on Experimental surgery performed by AI-driven surgical robot
I get your point, but wouldn't it be worse to have surgery for the rich and no surgery for the poors?
chychiu··on I don't think AGI is right around the corner
They are not intrinsically truth seekers, and any truth seeking behaviour is mostly tuned during the training process.

Unfortunately it also means it can be easily undone. E.g. just look at Grok in its current lobotomized version

chychiu··on Possibly a Serious Possibility
Doctor here

1. It’s generally difficult to quantify such risks in any meaningful manner

2. Provision of any number adds liability, and puts you in a damned-if-does, damned-if-it-doesn’t-work-out situation

3. The operating surgeon is not the best to quantify these risks - the surgeon owns the operation, and the anaesthesiologist owns the patient / theatre

4. Gamblers quantify risk because they make money from accurate assessment of risk. Doctors are in no way incentivised to do so

5. The returned chance of 1/3 probably had an error margin of +/-33% itself

chychiu··on The mysterious flow of fluid in the brain
Reading the core paper discussed in the article, along with all its context, will take ~hours. This article is a great 5-minute update on the latest research with a well written primer on the topic
chychiu··on One Logo, Three Companies
The Kanji for Mitsubishi is 三菱, which literally means “three rhombus”. It is possible that they were independently invented, but the hypothesis on family crest crossovers still feels more likely
chychiu··on The Investor Betting on People in Their 50s
From the deals that come my way, I see a lot more older founders with experience these days.

That said, I think the main reason why SV prefers younger founders is exactly because of their naivety + lack of understanding in their respective domains. E.g. It’s a lot easier for someone who has never worked in healthcare to try to disrupt healthcare, than someone who’s been institutionalised by the system they’re embedded in.

99% of these young founders won’t work out, but occasionally there will be one with a fresh idea that truly disrupts a system and gives the hypergrowth returns that VC guys want

chychiu··on Nvidia Blackwell GeForce RTX 50 Series Opens New World of AI Computer Graphics
Despite the flak Nvidia gets for VRAM sizes, 5090 seems to be a decent offer. Can’t say the same about the rest of the line.

FWIW, it appears the best homelab set up would still be 2-4x 3090 if you want VRAM for LLMs, but a single 5090 would likely be the best in class for prosumers on any less VRAM heavy tasks such as image / video generation or deep RL research

chychiu··on The barriers to AI engineering are crumbling fast
Precision = True Positive / (True Positive + False Positive) = 1 - False Positive Rate

On that note, I'm surprised the precision / recall for fin models are 80% / 50%

chychiu··on Complex systems emerge from simple rules
While the article is not particular in depth, it is mostly accurate and provides a mostly well intentioned introduction to the concept and how that could relate to emergent property of LLMs. I am curious why you think it was "utterly banal".

Additionally, abiogenesis is well accepted in academia as a prime example of emergence.

chychiu··on Ask HN: Who wants to be hired? (October 2023)
Just FYI the link to your resume is broken
chychiu··on Show HN: I made a landing page am I doing this right?
I'm by no means a UI expert, but 1. The email box / button needs to be much bigger. You probably want a more custom button style as well 2. Image loading speed is inconsistent; choice of image also. I will probably stick with a single image 3. Animation of the record is cool, but it should be triggered once only. There is no need for a big "X" button to reset it

I went through your blog post and I like your idea. Would love to see further iterations with the page and product

chychiu··on Show HN: Find the 10 highest and 10 lowest correlations to any stock
Great site! I've been playing around with it and seeing some interesting patterns.

One small typo: Highest -> Higest on the graphs

One recent theory suggests that the appendix acts as a safehouse for beneficial gut bacteria in the event that the gut microflora is wiped out:

chychiu··on Cathay Pacific faces crackdown as Hong Kong protests hit business
New to Hacker News - anyone know why the other thread about the Hong Kong protests (https://news.ycombinator.com/item?id=20673676) disappeared from the front page? It has >100 comments/upvotes and was posted 2 hours ago.
chychiu··on Hong Kong Airport shuts down as protesters take over
New to Hacker News - Is there a reason why this has disappeared from the front page within minutes? It was on the top of the front page as of 9:02pm AEST (4:02AM PDT).
chychiu··on The Billionaire Next Door (2007)
"His net worth isn’t something he says he ever thinks about. “I don’t waste time on it. Because at the end of the day, it’s a theoretical number that has no relevance. It’s not as if we have a bank account full with all that money and liquidity. I’m sorry, it’s not cash. It’s assets that are necessary so that people can do their jobs."

I wish more people can see it that way instead of touting the successes of billionaires just by virtue of their theoretical net worth

chychiu··on Haruki Murakami Introduces the Penguin Book of Japanese Short Stories
Have you read the rest of his works yet? The Wind-Up Bird Chronicle is a masterpiece in a similar tone to Hard-boiled Wonderland (but less cyberpunk)
