rajansaini··on RoboCat – A Self-Improving Robotic Agent
A successor to OpenLLaMA could make this possible. Imagine being able to deploy your own LLM.
rajansaini··on The LLama Effect: Leak Sparked a Series of Open Source Alternatives to ChatGPT
Read the InstructGPT paper and see alpaca. You just need instruction fine-tuning.

Unlike what the other commenters are saying, RLHF, while powerful, isn't the only way to get an LLM to follow instructions.

rajansaini··on Show HN: Kuboble.com – Minimalistic sliding pieces puzzle game
Seconded! If you make it easy/fun to share I (personally) would totally do so :)
rajansaini··on Turning nuclear waste into diamond batteries
Could it be useful to use these to charge long term batteries to be used millennia from now? So that future generations living centuries from now can have easy power when the fossil fuels run out?
rajansaini··on Ask HN: Which book can attract anyone towards your field of study?
I am surprised that Algorithms to Live By has not been mentioned. (Disclaimer: I am still reading it.) That book is both accessible and practical for any layman. However, just enough hints at variations of the discussed algorithms are given that even a non-technical reader might be motivated to dive further into theoretical CS and read a paper or two.
rajansaini··on Fakelish – Fake English word generator
You should check out the VOLT paper, I think it would work well. It's a new technique for splitting up a vocabulary into subwords while minimizing entropy. These subwords could then be mixed and matched, maybe by a neural model, for better results.
rajansaini··on Ask HN: Looking for a book on algorithms and data structures
I'm only a student, but I personally really liked https://jeffe.cs.illinois.edu/teaching/algorithms/

This is better for more advanced topics, like dynamic programming (well, advanced for me, anyway). I started out taking over an hour to solve the first problem in the problem sets, but they build on each other slowly, so I was soon able to see solutions within minutes. It took me a weekend to go through chapters I was struggling with, and I did really well on my coding interview the next day.

rajansaini··on Life as a public school teacher in the San Francisco Bay Area in 2021
In my experience anyone can be conditioned to love anything, and inspiring a love for learning something is the only stable long-term solution.
rajansaini··on Conway's Game of Life on FPGA
I think pyrtl was designed to enable abstraction in hardware design; it emits VHDL. Would be curious to know if anyone else has used this tool.
rajansaini··on Do wide and deep networks learn the same things?
Those are very interesting empirical results. This lecture explains the deeper vs shallow tradeoff theoretically: https://www.youtube.com/watch?v=qpuLxXrHQB4. He's an amazing lecturer; wish I didn't need subtitles!

(If you're too lazy to watch, it turns out that there exist functions that a shallow network can never approximate)

rajansaini··on Launch HN: YSplit (YC W19) – Automatically split and pay any bill
> I wish we'd see an app that teaches financial literacy and responsibility

I agree with you 100%. I'm not sure how feasible it is to build a business around it, though, since monetization techniques are likely to turn people off or harm the product. Bogleheads is an awesome existing resource, in case anyone's interested

rajansaini··on Show HN: A 64-step drum sequencer I built using React and Redux
That's really sick, UI is really pretty! As an idea for a follow-up project, I wonder how difficult it would be to make it non-deterministic; i.e. play a different variation each measure.
rajansaini··on Launch HN: Porter (YC S20) – Open-source Heroku in your own cloud
Sick project! When's the IPO? :D
rajansaini··on Venus could have been habitable for billions of years (2019)
Hopefully someone can provide more info, but apparently there are some bacteria in geothermal vents near Baja California that seem to be able to handle venus-like conditions. No idea what the details are though
rajansaini··on A Model of the Cosmos in the Ancient Greek Antikythera Mechanism
Why is that out of curiosity?
rajansaini··on Scientists begin building highly accurate digital twin of our planet
Seconded!
rajansaini··on Email from Jeff Bezos to employees
Didn't Yann LeCun do important work on CNNs there as well?
rajansaini··on Bill and Melinda Gates: America’s Top Farmland Owner
I'm not at all familiar with this domain, but wouldn't this kind of farm be incredibly vulnerable to a foreign threat?
rajansaini··on Collaborative Thinking
I'd like to play the foil to enrich the discussion.

Our instincts force us to seek validation and approval from others as individuals. I wonder if the success of blogs, Twitter, and academic research stems from incentivizing people to maximize that self-centered sense of ownership. For example, being first author on a well-cited paper is a powerful motivation to produce better research, which in-turn benefits the community and strengthens the institution.

rajansaini··on Markets are efficient if and only if P=NP (2010)
I didn't read the full paper carefully, but does this mean P != NP? :)
rajansaini··on Why deep learning works even though it shouldn’t
Intuitively, it seems like voice signatures, body language (like walking habits), and height/weight would play a larger role in helping humans identify a masked person than exposed facial features.

Because the network behind Apple's facial recognition software cannot have access to this kind of data (well, maybe voice, but that doesn't seem secure), I'm not sure this is a fair comparison.

Would love to be refuted, however.

rajansaini··on Home Studio Setup Costs Compared – 1980s And Now
I think today's technology does stifle creativity as well, though. Music was meant to be spontaneous and improvised, which is very easy to do with older synths and acoustic instruments. Production in a modern DAW is anything but that, and it's way less tactile.
rajansaini··on Open Problems in Robotics
That's a very interesting perspective. There have been many articles complaining about the "hype" behind ML, but I too wonder if DNNs could assist with controls, especially when it comes to reacting to sensor data. After all, it's just matrix math.
rajansaini··on Young children would rather explore than get rewards
I want to respond to your point about violin-playing, because I think it will open up an interesting discussion. Anecdotally, I was always motivated to practice my instruments by the same exploratory drive discussed in the article. I was taught to ask, "what if I did XXX this way?", i.e., what happens to my sound if I play long tones, what techniques do I need to play piece Y, how do I use scale Z to improvise?

Growing up, I found that those who ran on pure extrinsic factors with all discipline and no enjoyment either stopped or were stunted by locally optimal decisions. On the other hand, those who went on to study in university and play professionally seemed to derive the same obsessive enjoyment from their craft as I would a video game.

Do you think these data points further prove your point about emotional maturity? Or is there something more universal, that true success requires a fierce passion?

rajansaini··on Ask HN: Idea Propagation through Social Networks?
Whoa thanks!! I'll definitely take a look! Have you happened to come across anything dealing with optimal initial conditions that was particularly noteworthy?
rajansaini··on Ask HN: Idea Propagation through Social Networks?
This is gold to me, thank you.

I apologize, what do you mean by proxies?

Do you have any recommendations for a less-abstracted view of history (focusing on individuals rather than their emergent structures)? Or branches of philosophy that are particularly illuminating in this context?

rajansaini··on Ask HN: Idea Propagation through Social Networks?
In case anyone's interested, mindcrime's comment lead me down a series of links, and I found this: https://www.cs.cornell.edu/home/kleinber/networks-book/

Seems to be exactly what I'm looking for! If anyone knows anything at all in this area, no matter how small, please share!

rajansaini··on Ask HN: Idea Propagation through Social Networks?
Oooh very interesting, thanks! From what I've skimmed, it's so surprising how well his ideas transfer over to the present era!

Edit: Did not read the second half of your comment, absolutely!!

rajansaini··on Google-backed groups criticize Apple's new warnings on user tracking
Does anyone more well-informed than I know if Apple's recent pivots spells a reduction in ad-based revenue for mobile developers?
rajansaini··on Night owls have more grey matter in their brains than early birds
Here is an interesting point for discussion that I hope others may chime in on. What is the difference between being a night owl and experiencing jet lag? With enough discipline, one can recover from jet lag in a matter of days. Why then do some people believe themselves condemned to be a night owl or early bird?
