Yeah, they have a program that allows you to exchange your labor for capital.

It seems extremely unlikely to me that it wouldn't. I conjecture that no such word exists in any widely used human language. This would be a word who's meaning is not contained in the span of meanings of all other words in the language.

Can you think of one in english (or your native language)? You won't find it in any dictionary, since all those words have descriptions in terms of other words.

Having the model produce realistic interpolations through areas of the latent space that had no associated training data is surely something that people will be trying to make happen.

How does owning a property increase it's supply? I'm not an economist, but I think you have got to build houses to make more of them.

They certainly don't make that easier. But if the system supports a mutable link, you can have documents that always link to their own latest version.

IPFS does this by storing (mutable link, contentID) pairs in the DHT, which can be updated if you know the private key for the mutable link.

letlambda··on AlphaGo Zero: Learning from scratch
The hardware is certainly good enough to assist a person with a disability living in a ranch house with typical household tasks. As demonstrated by human in the loop operation.

letlambda··on AlphaGo Zero: Learning from scratch
The policy network is a function from board states to a scoring of moves. The policy network with the greedy heuristic, ie pick the highest rated move with no explicit look ahead method, plays at a high amateur level.

This was... unexpectedly good.

It effectively reduces the branching factor of Go from the number of moves available, to the number of moves actually worth considering.

>AI writing software will just get me another flavour of the wrong software. AI working out what people want the software to do would be useful.

Maybe we can deliver that wrong software in 100ms instead of 100 days.

>5) Intuitive leaps. e.g. Rubics cube.

I'm not sure what a Rubics cube has to do with intuition. But solving a Rubics cube is so firmly within the realm of doable that no one is going to call it AI anymore.

letlambda··on The Forgotten Mystery of Inertia
Walk around to the opposite side of the gyro wheel. If the acceleration is due to the rotation of the gyroscope, it still points out radially. If it was due to a mass out beyond the rim, you're falling on your head.

>There's nothing forcing companies to tell you what compound is harmful, where it is.

This is changing. But you still have the problem of over reporting. There are provisions to verify that your use of the material is safe, but it's so much easier, and so much less risky, to just slap the label on.

letlambda··on Dangers of CSV Injection
If you open a .csv file in excel and save it, you may find that it has converted any long numbers into scientific notation for you, and saved that as text. It will also get rid of any leading zeros for you.

letlambda··on Coding the History of Deep Learning
>Am I missing something fundamental here? Yeah, these aren't magic formula, they are just examples.

>In the first example, the method compute_error_for_line_given_points is called with values 1, 2, [[3,6],[6,9],[12,18]]. Where did those values come from?

It's an example. The first two arguments define a line y = 2x + 1, the pairs are (x,y) points being used to compute the error.

"To play with this, let’s assume that the error function is Error=x^5−2x^3−2"

This is just an example of a function used as exposition to talk about derivatives.

It isn't even an error function though. An error function has to be a function of at least two variables.

A new designated felon would be required to sell highly automated vehicles, the Cyber Security Officer.

You'll sign some documents certifying everything is fine, but of course, everything won't be fine. When your cars get hacked you'll go to jail for defrauding the government and/or manslaughter. I bet it pays real good though.

letlambda··on Demon-Haunted World
>instead, it tries to trick the reviewers, attempting to determine if it’s landed on a Car and Driver test-lot, and then switching into a high-pollution, high-fuel-efficiency mode.

This has actually been the case for some time. The car magazine wouldn't just go borrow a car, they would get one directly from the manufacturer. And the manufacturer would send a ringer, a vehicle with an EPA test-exemption that doesn't have to comply with any emissions regulations.

I suppose the era of Youtube car review channels is bringing that method to a close though.

letlambda··on A Bigger Mathematical Picture for Computer Graphics [video]
That may be largely due to massive amount of work put into the old way. Even if GA is just fundamentally a better idea for doing graphics, it doesn't have decades of software and hardware development to back it up.

Imagine selling this: I've got a new idea, with a mere re-education campaign for our developers, major graphics engine overhaul, and... convincing NVIDIA or AMD to implement some GA specific optimizations in hardware. We can have a much more mathematically satisfying code base!

letlambda··on Where will artificial general intelligence come from?
Consider every action that can be taken at this moment. For each possible action, consider every possible future (out to infinity) weighted by it's likelihood.

There are exclamation marks because some of these terms present minor practical problems. The whole, all possibilities out to the end of forever part of it, is easier said than done.

letlambda··on Where will artificial general intelligence come from?
http://www.alife.org/

Artificial Life is a field with very fuzzy boundaries. Roughly, computer systems that look like biological or ecological systems.

From an AL perspective, life evolves to function in it's ecology. The problem is not building an AGI, it's building an ecology in which AGI will emerge.

Oh... and hopefully, also one in which ruthlessly destroying other intelligent agents isn't a good survival strategy.
