Brazil puts China's BYD on list of shame for workers' past slavery-like conditions Brazil has put China's BYD on a ‌registry of employers who have subjected workers to conditions similar to slavery, after a 2024 scandal in which Chinese workers were said to have been victims of huma...

The relationship, between China and Latin American countries, is also quite complicated. Yesterday, for instance, Brazil labeled BYD as a company that uses slave labor:

Hypothetically, could Trump have dropped a nuclear weapon on Iran and be immune from criminal prosecution?

How do you distinguish between an actual change in opinion versus an inherent error that's always present in sampling?

4/In other words, instead of making many thousands of plastic objects and that each have their own distribution, there could be a set of invertible geometric objects that could be homomorphically rotated and twisted to different shapes and that would provide analytic solutions.

3/The advantage of this analytic approach would be that these geometric shapes most likely have differomorphisms that would allow you to find invertible geometric units that then could be applied homomorphically.

2/That is, there are geometric -- or hypergeometric -- shapes that provide analytical solutions to the probability distributions.

1/I know little about robotics; so this question may seem naive. But, I wonder if there are analytical equations for the distributions of correct probabilities of robotic grasping.

How are you going to enforce this?

5/ But I do think if you don't understand why it works, you're going to have difficulty to work in all cases and may have trouble either generalizing from it or optimizing it.

But, maybe I'm wrong. Or maybe $1 billion will help find why it works. Or maybe it won't.

5/ Then, at 52:18 in the linked video, LeCun casually mentions that, although this new approach seems to work well (see the paper for examples), he doesn't understand why it works. No one, it seems, understands why it works.

Does this mean that this new approach won't always work? Not necessarily.

4/...abstraction is needed for machine learning. In other words, the predictions in a feed forward neural network aren't concerned with pixels or tokens but abstractions of physical reality (that can be embedded in vectors).

Great! Sounds like an idea that has a lot of promise, I thought.

3/ Briefly, the idea is that LLMs aren't feasible for the physical world because they're too granular. That is, higher level abstraction is needed. Consider, the equation f=ma isn't at the atomic level. Rather, it's concerned with abstractions such as mass and force. LeCun argues a similar...

2/ Curious, I read the paper. Thought it was fascinating but became lost in the mathematical details. Wanted a higher level abstraction of how it works. Then, I found this lecture by LeCun last year:

Yann LeCun Raises $1 Billion to Build AI That Understands the Physical World Meta’s former chief AI scientist has long argued that human-level AI will come from mastering the physical world, not language. His new startup, AMI, aims to prove it.

1/Today, read that Yann LeCun raised $1 billion (US) for an AI that understands the physical world:

The company, Advanced Machine Intelligence, is going to be based on LeCun's idea of joint embedding predictive architecture:

Qatar warns that oil could double to $150 a barrel Qatar's energy minister has warned that the price of a barrel of oil could double to more than $150, dragging down global economies.

The minister of oil in Qatar has warned that, if the war with Iran doesn't end soon (this is undefined), then the price per barrel of oil could rise above $150. That is, the realities of the war are dictating the price of oil, not what Trump says:

This is an incredible statistic! Also, worth pointing out, there seem to be about 58k people indicted in '16. So, the percentage NOT getting indicted is: 57944/58000 = 99.90%. Then: 1 - 99.90 = .01%!

Unicode - Wikipedia

2/The solution is to either install/upgrade a spell checker that has a Unicode that recognizes Maori words or upgrade your present Unicode that MSFT spell checker uses.

1/Interesting. If you don't know, a spell checker is reliant on Unicode. That is, what the computer "sees" is the Unicode equivalent. What MSFT's spellchecker understands, through its Unicode equivalent, is not what you see. That is, it could simply see something it doesn't recognize.

Washington Post Co. Sells Newspaper and Keeps Kaplan Kaplan Inc., now makes up a larger portion of the Washington Post Company, which Monday announced the sale of The Washington Post for $250 million to Jeff Bezos, the founder and CEO of Amazon.com.

2/

This was why it was profitable. When Bezos bought it, it had an operating loss of about $40 mil. It now has one of $100 mil. That is, nothing has changed -- except that Bezos didn't buy the profitable part of the company:

1/ (Haven't read the article.) A reminder: the Washington Post was sold to Bezos without Kaplan Higher Ed. That is, the latter made up half of the revenue and ALL of the profits of the Post, before Bezos. In other words, the Washington Post used to be a test prep company w/a newspaper.

If this is disprovable through data, would JD change his opinion and then search for the (true) causes of why housing is expensive?
