Looking at the team seems to be all ex-openai employees and one of the cofounders worked on building gpt3. Will be exciting to see what they are working on and if it will be similar work to openai but more commercialized.

I wonder why they left Open AI? Maybe they didn't like Microsoft's influence, or they felt that Open AI wasn't really open, or that it didn't have enough focus on safety?

Or they just didn't like their boss that much?

This looks quite promising!

I agree! Love the public benefit aspect of Anthropic.

I can't find any mention of who currently comprises the core research team. It mentions Dario Amodei as CEO, and their listed prior work suggests some others from OpenAI may be tagging along. However, the success of this group is going to be highly dependent on the caliber of the research team, and I was hoping to see at least a few prominent researchers listed. I believe OpenAI launched with four or five notable researchers as well as close ties to academia via the AI group at Berkeley. Does anyone have further info on the research team?

Chris Olah posted that he is involved.

Seems you can see some of them on their company linkedin page : https://www.linkedin.com/company/anthropicresearch/about/

ansk3• 5 years ago

LinkedIn authwall, we meet again. Could someone list the researchers (if there are any, and assuming there are only a few). Frankly, it's not a great sign that the Anthropic site isn't touting the research team itself and LinkedIn sleuthing is even necessary.

Looks like an interesting project. The thing is, I don't think ideal qualities like "reliable, interpretable, and steerable" can really be simply added "on top of" existing deep learning systems and methods.

Much is made of GPT-3's ability to sometimes do logic or even arithmetic. But that ability is unreliable and even more spread through the whole giant model. Extracting a particular piece of specifically logical reasoning from the model is hard problem. You can do it - N-times the cost of the model. And in general, you can add extras to the basic functionality of deep neural nets (few-shot, generational, etc) but with a cost of, again, N-times the base (plus decreased reliability). But the "full" qualities mentioned initially would many-many extras-equivalent to one-shot and need to have them happen on the fly. (And one-shot is fairly easy seeming. Take a system that recognizes images by label ("red", "vehicle", etc). Show it thing X - it uses the categories thing X activates to decide whether other things are similar to thing X. Simple but there's still lots of tuning to do here).

Just to emphasize, I think they'll need something extra in the basic approach.

Go check out the entire project of captum for pytorch. I assure you that gradient based explanations can be simply added to existing deep learning systems...

joe_the_user3• 5 years ago

All sorts of explanation scheme can and have be added to existing processes. They just tend to fail to be what an ordinary human would take as an explanation.

Note - I never argued that "extras" (including formal "explanations") can't be added to deep learning system. My point is you absolutely can add some steps at generally high cost. The argument is those sequence of small steps won't get you to the ideal of broad flexibility that the OP landing page outlines.

Excited for this! While OpenAI has generated plenty of overhyped results (imo as an AI researcher), their focus on large scale empirical research is pretty different from most of the field and had yielded some great discoveries. And with this being started by many of the safety and policy people from OpenAI, I am pretty optimistic for it.

Their paper "Concrete problems in AI safety"[1] is interesting. Could be more concrete. They're run into the "common sense" problem, which I sometimes define, for robots, as "getting through the next 30 seconds without screwing up". They're trying to address it by playing with the weighting in goal functions for machine learning.

They write "Yet intuitively it seems like it should often be possible to predict which actions are dangerous and explore in a way that avoids them, even when we don’t have that much information about the environment." For humans, yes. None of the tweaks on machine learning they suggest do that, though. If your constraints are in the objective function, the objective function needs to contain the model of "don't do that". Which means you've just moved the common sense problem to the objective function.

Important problem to work on, even though nobody has made much progress on it in decades.

So they're on safety, explainability, steerability and so-forth. It seems like you could call these "holistic" properties and they have always been hard to add to add to a system - indeed, it seems like in a conventionally constructed system they tend to have to be engineered-in from the start.

The success of deep learning might be something of a curse - it's go enough success that creating a safe system seems to automatically be modifying a neural net to be safe despite it not having the "engineered from the start" quality.

The success of deep learning might be something of a curse

Possibly. In AI, someone has a good idea, there's great enthusiasm, people in the field predict Strong AI Real Soon Now, the good idea hits a ceiling, and then people are stuck for a while. AI has been through four cycles of that. The ceiling of the current cycle may be in sight.

The next big problem is, as they say, "safety", or "common sense". Nobody really has a handle on how to do that yet. Checking proposed explorations against a simulation of some kind works if you can simulate the world well enough. Outside that niche, it's hard.

Collecting vast amounts of data to predict what can go wrong without an underlying model runs into combinatorial limits. More things can go wrong than you are likely to be able to observe.

Good that there are people thinking about this.

Is it appropriate to ask an on-topic but naive question?

It seems as a layman that safer and more legible AI would come from putting neural networks inside of a more 'old-fashioned AI' framework - layers of control loops, decision trees etc based on the output of the black box AI. So at least if your robot crashes or whatever, the computer vision output is in some legible intermediate form and the motion is tractable to traditional analysis.

This can't be an original thought, it must already be done to a large extent. But I get the impression that the way things are going is to get the trained model to 'drive' the output, for whatever the application is. Can someone with current industry knowledge comment?
