Very pleased to say my paper "Making AI work for Investigative Journalism" is finally available. Here's my review of what's been done, why it's been hard to use AI for "finding patterns" in data, and suggestions for how to make progress.

When the objective function term to incorporate a concern into an optimizer is the negative of one already there for someone else's interest, then you have discovered that you need negotiation between parties.

I should clarify, this approach is explicit in the organization's mission. So I guess not merely "my view"https://www.partnershiponai.org/about/

My view is that
@PartnershipAI has to be more than "don't do that with AI." We have to say what is better, both to effectively mitigate harms and to create new possibilities. Not just criticism, but design.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

“Externality” is a great word for talking about a certain type of market problem, but I’m seeing it evolve into “any bad outcome.” It’s got a technical definition that’s probably worth defending. E.g. low driver wages is not an externality for Uber. It’s entirely internal.

Good news: the existence of arbitrage between regulatory regimes doesn't mean regulations are bad, because they compensate for externalities. Bad news: existing regulations do not seem to be addressing the externalities they were designed to fix. https://www.gsb.stanford.edu/faculty-research/working-papers/externalities-arbitrage …pic.twitter.com/0WEi5XI25u

YOU GUISE MAGNETISM IS JUST MOVING ELECTRIC CHARGE IN A RELATIVISTIC REFERENCE FRAME! I'm still excited about this. I guess because it's the first "unification" principle in physics where I can personally follow the math.

Asked my students what percentage of retail sales were handled by e-commerce (as opposed to brick-and-mortar). Their estimates ranged from 85% to 40%, with an average around 60%. The real number is 11%. Small wonder we are overestimating the effects of change in some areas.

Dear critics of capitalism: what's a good, smart reference that discusses the idea that some companies are so powerful and have so much effect on people's lives that they are effectively making public policy?

TIL magnetism can be understood by analyzing moving charges with special relativity. I studied physics and how did I not get this before? Shoulda taken that EM class after all, I guess. Magnets, how do they work? Now I know.https://www.youtube.com/watch?v=1TKSfAkWWN0 …

Whether they know it or not, people who advocate for causal evaluation in business and society are fundamentally re-thinking how power works. Statistics & research design are much easier to get right than the underlying questions about power.

So if I invest in an index fund and buy a short position on the included fossil fuel companies, that's financially equivalent to not investing in fossil fuels. But is it equivalent in the real economy?

Experimenting today with putting some of my savings into low-carbon index funds. Chose Vanguard's ESGV fund primarily because of low expenses. I expect reasonable returns but mostly this move forces me to think through the implications, mechanics, and effects of social investing.

I mean, if it's a good idea, someone has already thought of it. Part of being a mature researcher is understanding that. So I went looking and sure enough, Rolnick and co already had this. Now I'd like to evaluate real-world feasibility. https://arxiv.org/abs/1906.05433 pic.twitter.com/I0RWX5yez0

What's the largest database of per-product carbon footprints you know? Not an idle question. I want to know if you can build this into real product recommendation systems.
