You Can Always Get What You Want, But Not What You Need (2016) [video]
- rmateus 9y agoMulticriteria value decision analysis theory and methods are able to provide the solution to model the need (utility). For instance, in reinforcement learning the payoff (goal) function is always a given without any depth consideration about its construction. It can be modeled by using the methods referred previously.
- xapata 9y agoI thought that theory told us multicriteria optimization is intractable?
- arbie 9y agoIf that's the same as multivariate opt, there are billion-dollar industries that rely on it every day.
- xapata 9y agoNo, unless I've mistaken the phrase, they're not the same. I'm thinking of the problem when competing criteria can't be satisfactorily combined as inputs to a function with a scalar output. This comes up in ethical paradoxes, for example.
- rmateus 9y agoMaking value trade-offs between competing criteria ultimately boils down to hard ethical choices (not exactly paradoxes)
- rmateus 9y agoMulticriteria optimization is distinct from multicriteria value decision analysis. The former does not model the value/utility of the criteria, while the latter does. If you do not model value/utility (what you need) then you cannot solve the underlying multicriteria problem.
- akshayB 9y agoCompanies make things that they can sell in a marketplace it is necessarily not what that place needs. For example social media companies just want to sell their social networks in any country with internet irrespective of that country have drinking water problem or humanitarian crisis.
- jimbokun 9y agoYes! The sentiment is something I (and I suspect many other engineers) feel, but not able to express it nearly so simply and elegantly. Before you sit down and start writing that code or creating that new algorithm, stop and think about what you really want to achieve.
- tw1010 9y agoGreat video. I think the book The Elephant in the Brain is required reading in this context: http://elephantinthebrain.com/ http://elephantinthebrain.com/
- truculation 9y agoFascinating. Instead of banning money or fixing prices (did they try that in Russia?) we retain free markets but now with a new layer of government intervention. Not intervention by social spending or regulation but by buying and selling according to the dictats of an AI. And the utility function of this AI is set according to what exactly? My guess is it would have to be according to our values, not to specific goals: https://www.youtube.com/watch?v=tZBViI8ZaU0 https://www.youtube.com/watch?v=tZBViI8ZaU0
- crdoconnor 9y agoThe Soviet Union always had money and banking. It was just less meaningful than it is in America.
- fossuser 9y agoThis is the goal alignment problem that MIRI, FHI, and some safety groups at Open AI are working on. It seems like a hard problem to get right (with bad consequences if not aligned super intelligence happens first).
- zokier 9y ago> but now with a new layer of government intervention As far as I can tell, the government is the least active actor in this area, so curious choice of picking it here.
- UncleEntity 9y ago> Not intervention by social spending or regulation but by buying and selling according to the dictats of an AI. Which would still run up against The Economic Calculation Problem which has constrained all central planning proposals and (probably) always will. Once they solve that then we can talk about an AI which can predict the outcomes of billions upon billions of individual decisions which are made by market actors to fulfill their wants and needs.

- debt 9y agoPeter Norvig’s book A modern approach to AI is pretty cool. I don’t know what they use now in 101 AI courses but I remember that book being very complete. I still believe though that hard AI will only ever be possible if we ever make serious breakthroughs in the material sciences.

- dikkechill 9y agoTo differentiate between needs and (economic) wants, I found the "fundamental human needs" framework quite useful: https://en.wikipedia.org/wiki/Fundamental_human_needs https://en.wikipedia.org/wiki/Fundamental_human_needs (as developed by Chilean Economist Manfred Max-Neef). Basically: Subsistence, Protection, Affection, Understanding, Participation, Leisure, Creation, Identity and Freedom.
