sayonaraman··on Leaked grant proposal details high-risk coronavirus research
well how about establishing safety procedures, research guidelines and international regulation body governing dangerous GoF research so that such outbreak doesn't happen again.

I doubt Wuhan GoF researchers will be publishing their findings anytime soon, until then it's all speculation.

you mean figuring out what caused a global pandemic, deaths of millions of people and trillions dollars of economic damage is of no consequence?

sayonaraman··on Deep Learning's Diminishing Returns
> new approach discovery

a good example is discovery of attention mechanisms/transformers replacing more cumbersome and computationally expensive RNNs and LSTMs in NLP and more recently outperforming more expensive models in computer vision.

sayonaraman··on Deep Learning's Diminishing Returns
I'm wondering if there is a way to combine optimization of model weights in a neural net with a set of heuristics limiting the search space, as a sort of rules engine/decision tree integrated within ANN backprop training. Basically pruning irrelevant and redundant features early and focusing on more informative ones.
sayonaraman··on Deep learning meets vector-symbolic AI
this is awesome, thanks for the link! There seems to be mutual propagation from NLP to CV and from CV to NLP, i'm wondering if there is a visual counterpart for these "Random Encoders". The SOTA for image/text embeddings currently seems to be CLIP [1].

sayonaraman··on Deep learning meets vector-symbolic AI
you might also be interested in the recent work on "resonator networks" VSA architecture [1-4] by Olshausen lab at Berkeley (P. Kanerva who created the influential SDM model [5] is one of the lab members).

It's a continuation of Plate [6] and Kanerva work in the 90s and Olshausen' groundbreaking work on sparse coding [7] which inspired the popular autoencoders [8].

I find it especially promising they found this superposition based approach to be competitive with optimization so prevalent in modern neural nets. May be backprop will die one day and be replaced with something more energy efficient along these lines.

sayonaraman··on How people reason their way through echo chambers and what might guide them out
>If there were a way to objectively quantify a news outlet or newsperson’s track record with accuracy, that might be a start.

The problem with this sort of "fact checking" is that its keepers are biased as well. So you need a "fact check" on a "fact check" which might lead to stack overflow eventually. Unless you can objectively judge the accuracy yourself. And track record means nothing if say a reputable news outlet is purchased by a billionaire with a political agenda.

I think many people break through the walls of their echo chambers when they stumble upon some basic inconsistency and discover they are being lied to by seeing e.g. raw footage of an event vs. its media interpretation.

For many people however finding the truth is not interesting or important enough. I guess echo chambers are for those who deserve them.

sayonaraman··on Reasonable Doubt
I watched most of it, the coroner report and testimony alone should have been sufficient as reasonable doubt, not to mention police training materials and witness testimony which showed Chauvin did exactly as instructed per standard procedure, not to mention aggressive crowd including a former MMA fighter threatening the officers and diverting their attention during arrest, not to mention Floyd's prior history of high BP and heart problems, and earlier arrest where he ended up in hospital under the same circumstances, not to mention the lethal dose of fentanyl combined with meth in his system, not to mention prosecution not able to procure any evidence of Floyd dying from neck restraint besides speculation and emotional speeches.

Chauvin's lawyer did a decent job, but it was a travesty of justice with politicians demanding "the right verdict" or else cities will burn and aggressive mobs outside intimidating the jury, not to mention an actual BLM activist on the jury. It was a 'banana republic' style trial.

sayonaraman··on Home ownership is still mostly renting

sayonaraman··on Home ownership is still mostly renting
The “what else you could do with the money” argument is standard in finance/economics , in fact it’s the cornerstone of the famous Black-Scholes formula for pricing options which takes into account "risk-free" interest rate.
sayonaraman··on Reasonable Doubt
I've kind of lost my faith in the judicial system after they gave in to the mob and convicted Derek Chauvin, with plenty of reasonable doubt to set him free.

The legal system is as political, biased and arbitrary as any other part of our lives. There is no justice, only luck.

sayonaraman··on Ask HN: What're some great cities to live for $2k USD per month?
Definitely worth considering too. Bratislava is really close to Vienna, probably more West European in culture than others because of physical proximity and history.

I'd explore all these, may be do a few months stay in each city, that would be really cool experience you could tell stories about.

Btw if you go further east check out Chernivtsi, it’s a hidden gem in the East Carpathian mountains.

sayonaraman··on Ask HN: What're some great cities to live for $2k USD per month?
Bratislava

2-bd start at around 500 EUR/month utilities included, but can go higher if you choose a good location and bigger apartment. For 600 EUR you should be able to find a solid one, with luxurious ones in good location starting at 750 EUR/month.

Good internet speed, friendly people, european culture, quick flight or train ride to anywhere in Europe, pretty girls.

sayonaraman··on Facebook tried to make its platform a healthier place, but it got angrier
Exactly, you can probably add Washington Post, CNN and The New York Times to the list. If not for the continuous lies and “outrage engineering” by mainstream media BLM riots wouldn’t have happened and hundreds of small businesses wouldn't have been destroyed in 2020, not to mention all the innocent people injured and killed for fake political cause.

Facebook and other social media are definitely partly responsible for the outrage culture and divisiveness plaguing the country.

But I assume it’s a difficult problem for algorithms to detect political agenda, as it seems to pervade every aspect of news these days.

sayonaraman··on Soar Cognitive Architecture
there is a list of popular cognitive architectures (including Soar and more recent ones from the likes of Kanerva and Eliasmith): https://en.wikipedia.org/wiki/Cognitive_architecture#Notable...

Eliasmith created "Semantic Pointer Architecture" which is sort of a crossover between CS and CogSci https://en.wikipedia.org/wiki/Spaun_(Semantic_Pointer_Archit..., also see his book on "How to build a Brain"

I wish the current AI research would get unstuck from local minima of deep learning, there's been so much progress in cognitive sciences in the last few decades.
