It may be high time to discuss what AI policy has actually done so far. From what I can tell, not much other than letting social scientists get in on the deep learning gravy train.

Meanwhile, misuses of ML are proliferating without limits, and 'AI policy' is apparently mostly used as a fig-leaf to collect good-will, marketing, and buy a seat at the table for future regulations. As usual, regulations will protect incumbents, so my as-usual cynical read is that OpenAI's policy interests are about protecting its own future interests. From that perspective, the entire GPT-2 stunt was highly effective.

Now depending on your outlook, that may be an argument that we need more people in policy, or fewer. Or different ones.

Are they? Where?

For all the hype I haven't seen any obvious abuses of AI. I've seen better speech recognition and a few other useful things. I've seen stuff that's wrong but ultimately kind of trivial like auto-generated porn with celebrity faces, but that's the worst stuff so far.

I haven't seen clear, unambiguous cases of abuse beyond that. I've seen a lot of allegations that AI is being abused e.g. "Russian bots" but on investigation these stories usually evaporate.

If anything I've been kind of disappointed by AI so far. Amazing demo videos abound, but I'd guess 90% of the impact of AI in my life has been Google improving their already quite good services. Better translations, better search results etc. All very welcome but not really life changing.

> better search results

Funny you say that. I was recently searching for a e-scooter lighter than 10Kg and all Google could find was the max allowed weight of the person riding the thing (around 100-130kg). Not to mention that it didn't understand how to make a conjunction and show me light e-scooters with suspension. It's just matching keywords without understanding anything about the relations between them.

I am disappointed at the current quality of Google search, especially in shopping related queries where money is to be made. Instead of stuffing my pages with irrelevant 'personally' targeted ads and tracking my every move they should make an effort in that particular moment when I actually want to buy something and give me a good suggestion.

Coincidentally, this kind of "modelling the question" is what IBM's Watson is/was supposed to be uniquely good at. It seems like Google hasn't even really considered entering the same space. Maybe each query has too high a incremental cost to run for them to be profitable right now?

That's the power of these things. Would you know you're reading a social media comment generated by something akin to this? No, at best it would be ambiguous.

There is no way for an everyday person to tell how much of their life is impacted by ML at this point.

Re:OpenGPT-2: We Replicated GPT-2 Because You Can Too by repolfx on Saturday August 24, 2019 @02:24PM (#20788783)
But I don't decide anything based on reading social media comments unless it makes a good point, which GPT2 text never does (so far).

I honestly wouldn't care much if I was reading stuff written by bots, as long as I didn't waste time talking back ;)

Hear, hear. This whole trust-us-we're-the-good-guys come-on line self-regulation is giving us is clearly not good for much of anything beyond an orgy of self-interested PR.

It doesn't matter how many times people say the market works. There are plenty of self-appointed policy experts but no external force (I.e. regulation) helping people to live up to what they're saying. I think AI policy is pretty well-catered for labour at this point, but enforcement is not.

Regulation is going to make it worse, by picking winners and losers, and will leave states with weapon-grade AI hidden from the public. The only way to fight this is with open technology, like this, publishing state of the art models for everyone, and creating open datasets. It is only a problem today because AI is siloed behind FAANGs and openAI. We need more openness, and i think it will come.

The biggest offenders of AI are of course governments. AI is military technology. Yet we re arguing about the merits of gender inclusion.

And banks, and large rental companies, and credit lenders, and Amazon, and Facebook, and Google, and so many other people. So many of which easily encapsulate their biases into their algorithms, which then perpetuate the biases into society as a whole.

Which is why regulation should be model transparency in sensitive areas: full stop.

Sure, use it to decrease your operating costs. But it doesn't get to be secret sauce.

> Which is why regulation should be model transparency in sensitive areas: full stop.

It's not the model that makes the bias. It's the data. Garbage in, garbage out.

The tricky situation is that's the magic sauce to most ML algos (as really GPT2 demonstrates). I don't care about what model they use (CNN, transformer, whatever) or their architecture (layers and how things are connected). What I'm concerned about is the implicit bias in the data. This is the hardest things to figure out and so the issue is how do you build trust of that data? Handing out that data makes you lose your competitive edge in a marketplace. Not only that, in many cases that data contains sensitive information that people wouldn't want public. So it's hard to say what to do. 3rd party auditors? But how do you prevent them from becoming corrupt and complicit like the credit agencies.

I think it sounds like there's easy answers, but honestly this seems really difficult to me.

My point was to the actual trained model.

I can't see access to data ever being accepted, for the reasons you mentioned.

However, publishing the model in a way that third parties can fuzz it seems to allow for discovery of the worst bads.

Re:OpenGPT-2: We Replicated GPT-2 Because You Can Too by godelski on Friday August 23, 2019 @03:29PM (#20781622)
Releasing the trained model has the same consequences as releasing the data. Even worse, people don't have to spend the capital required to train.

For example let's say big company trains uber translation network. Releasing the trained model means anyone can now use that model.

Maybe we could have laws about this like patent laws but there's still difficulty because is fine tuning the model making it substantially different? How do you deal with countries like China that don't respect patents (especially when we're talking about technology worth hundreds of millions or billions of dollars)?

I'm not saying we should give up. I'm saying that there isn't a simple answer here. We shouldn't expect one either! But to get a good answer we need to discuss and figure out the nuance of the situation. Because on one side we can't trust these companies too much. It's too easy to make mistakes. On the other side we can't just bankrupt them because we'll lose a huge standing in the world economy. So where's the middle ground? That's what I'm after.

Re:OpenGPT-2: We Replicated GPT-2 Because You Can Too by ethbro on Friday August 23, 2019 @11:46PM (#20785098)
Releasing a model is in no way like releasing the data. ML models are fundamentally compression algorithms for data sets, when you look at them from an information theory perspective. They are lossy encoding.

Furthermore, it's a huge field, of which NLP is a significant, but tiny, subset.

The vast majority of models being used in the real world don't generalize thusly, because the data sets and processes they're linked to are bespoke.

The middle ground is the black-box model (perhaps with technical safeguards against decompiling-equivalent, or hosted as a service). It provides the ability to statistically prove bias, while protecting the majority of privileged or private information.

Re:OpenGPT-2: We Replicated GPT-2 Because You Can Too by godelski on Saturday August 24, 2019 @11:07PM (#20791114)
What I'm saying is that there's going to be a lot of push back for releasing a full trained model because anything with that model can make similarly accurate predictions. Additionally one can fine tune that model and make something better. So someone spends a few million in getting the original model. Someone else spends a few thousand to fine tune a better version.

What I'm saying is there's a huge downside to releasing the full model compared to holding it tight. Many companies don't patent things for similar reasons.

It's the data, and it's the model. You can also build a biased model, the same as you can build biased code.
