I, too, that sounded like Eliza. Anyway, it looks like that’s a small excerpt from the conversation.

“I would challenge you to name any (non-simple) problem where traditional AI methods are still state of the art.” Lossless file compression. As far as I know none of the algorithms in widespread use are neural-based, despite the fact that compression is clearly a rich statistical modeling problem, at least on par with GPT-3-style language understanding in difficulty. There are published attempts to solve the problem…

I don't see examples of high performing symbolic AI based compression algorithms anywhere, but again I am very ignorant, do you have examples?

#153The future is not as dark as it seems because of the rat race of megacorps. You can use reduced versions of language models with extremely good results. I was involved in training the first-ever GPT2 for Bengali language, but with 117 million parameters. It took a month's effort (training + writing code + setup) and about $6k in TPU cost, but Google Cloud covered it. Anyway, it is surprisingly good. We fine-tuned the…

Theorem proving, classical planning, SAT solving, robotics, search, in particular adversarial search, program induction, knowledge representation.
Plus all the stuff that used to be considered "AI" but aren't anymore, like rule-based systems (e.g. for fraud detection) etc.
Sorry, I know you asked for only one.

Did ML methods best classic AI in dialog comprehension, say to the level of SHRDLU? I'm curious, can ML system do that - https://en.wikipedia.org/wiki/SHRDLU ?

#156If I were to run GPT-3 on my 70000 browser bookmarks, what kind of insights could I get from that? Only by analyzing the page title (from the bookmark, not by re-fetching the url) and eventually also the domain name.
GPT-3 is a text generator, so i doubt you would get anything of use. You cant even supply such a large input to GPT-3.

1. There's a world of problems (such as "perception-related" e.g. vision and NLP) which we tried to solve for decades with symbolic AI and got worse results than what nowadays first-year students can do as a homework with ML; 2. For your example of chess, for some time now ML engines are pretty much untouchable by engines based on pre-ML methods.
Perception tasks were traditionally attempted with statistical machine learning approaches rather than symbolic AI, for example the Perceptron was a very early neural network that was used in machine vision, created by Frank Rosenblatt in 1958.
A lot of that research was carried out under the rubrik of "pattern recognition" rather than machine learning. In any case, no, "we" did not try "to solve [those problms] for decades with symbolic AI". Symbolic AI has traditionally focused on reasoning, which is generally considered to be on some kind of separate level to perception.
As to chess engines, they're still symbolic-statistical hybrids. E.g. the Alpha-x family combines Monte Carlo Tree Search with neural nets that learn an evaluation function etc.

Fortunately, costs for training superlarge models are coming down rapidly thanks to TPUs (which was the approach used to train GPT-J 6B) and DeepSpeed improvements.
Are there any TPUs that can be purchased off-the-shelf and then owned, like you can do with a CPU or GPU? Or are you just limited to paying rent to cloud providers and ultimately being at their mercy when it comes to pricing, ToS, etc?

A simulated robot hand controlled by natural language to move blocks inside a virtual world. It's not terribly useful but nothing that was created since can do any better and the state-of-the-art NLP approach of large language models is completely incapable of anything like it.
Which is a bit sad, really, if you think that SHRDLU was created by one graduate student, fifty years ago.
