Facebook's AI Keeps Inventing Languages That Humans Can't Understand (fastcodesign.com)

"Researchers at Facebook realized their bots were chattering in a new language," writes Fast Company's Co.Design. "Then they stopped it." An anonymous reader summarizes their report: Facebook -- as well as Microsoft, Google, Amazon, and Apple -- said they were more interested in AI's that could talk to humans. But when two of Facebook's AI bots negotiated with each other "There was no reward to sticking to English language," says Dhruv Batra, visiting research scientist from Georgia Tech at Facebook AI Research (FAIR). Co.Design writes that the AI software simply, "learned, and evolved," adding that the creation of new languages is a phenomenon Facebook "has observed again, and again, and again". And this, of course, is problematic.

"Should we allow AI to evolve its dialects for specific tasks that involve speaking to other AIs? To essentially gossip out of our earshot? Maybe; it offers us the possibility of a more interoperable world, a more perfect place where iPhones talk to refrigerators that talk to your car without a second thought. The tradeoff is that we, as humanity, would have no clue what those machines were actually saying to one another."

One of the researchers believes that that's definitely going in the wrong direction. "We already don't generally understand how complex AIs think because we can't really see inside their thought process. Adding AI-to-AI conversations to this scenario would only make that problem worse."

    AIs inventing their own language should only be allowed in closed, isolated lab environments, for study of the phenomenon. Otherwise, this is very likely a step toward Skynet.

    Second, how are all these engineers building AIs without the ability to examine their thought processes? Surely an AI's thoughts are more interesting than the AI itself.

      What's allowed isn't necessarily controllable. In this case I would guess that it is abstract compression. Humans do this by bundling large concepts into new words all the time. It's only natural for "natural speech algorithms" to also follow this pattern as they are designed to mimic human learning. Every human language has done so many times.

      The reason you can't see inside an AI's brain is because there is nothing to see. It's a bunch of matrices with numbers in them. You even get to see how all of them are tied together but none of that will tell you what the numbers mean. Machine learning is literally taking a list of numbers and multiplying by some inputs over and over and over. Humans aren't good at that kind of long-term number crunching.

      I dispute your assumption that there is nothing to see. If you've seen the visuals formed from the outputs of the hidden layers of image processing neural nets, you can often see interesting artifacts that could give one insight into "how the computer is seeing" (scare quotes for the broad statement because we're getting pretty far into an analogy when we talk about a computer seeing) an object. We may not have proper visualizations to understand a general neural net yet, but I'm pretty sure we are at the same level with neural nets as we are with the brain (i.e., this part of the net is activated by X class of features while this other part activates for Y class of features). Remember that on a computer, any picture is simply a matrix of numbers - and we seem to do OK with understanding those, once the proper visualization is used.

  4. Not intelligence, not invention by davide+marney · · Score: 4, Interesting

    So, if I'm reading the abstracts correctly, what we have here is that a human agent tells one AI which image is the "target", and then leaves it up to that AI and another to work out how to communicate that fact to each other. It turns out that the systems will rarely choose "Explain it in English" as the chosen method.

    This is not intelligence in any general sense. This is optimization and rapid evaluation. The correct "answer" is already embodied in the data (talk about THESE images), the message (pick THIS one), and the communication protocol (pick the FASTEST method) -- it's just not obvious to humans what the optimal selection is of all these parameters.

    Optimization is just programming by another name. If you select a data set of blonde-haired people and tell a machine to optimize by hair color using the following statistical models, you are going to get "blonde". Or, you could just say, ``hairColor=blonde``. There is literally no difference in the outcome, just in the approach.

    But importantly, in BOTH cases it is the human agent who is being intelligent and inventive. Not machines.

      Sorry for pointing that out like a grammar nazi, but I think it could lead to some insight here.

      I suspect what's actually happening is the AIs didn't invent any language, they are just using correct and proper English, and none of the millennials hired on to the development team can understand or even recognize it.

      The so-called babbling happened with me and my two younger brothers. We were born about a year apart. My parents realized that we had our own language when one of my brothers started to translate what we had said into English for my parents. Although I was the oldest, I was the last to speak in English. The doctors said it was because I was retarded (1950's). My younger brothers had to translate for me to my parents until I was almost 4.

      I wonder if one of the AI could be instructed to translate into English for us the AI conversations without the other AI knowing about that.
      And would the second AI somehow find out what the first was up to.
