Chris Stucchio explains the mathematical impossibility of simultaneously satisfying multiple fairness criteria in algorithmic decision-making systems.

In analytical philosophy, armchair philosophers ask theoretical questions like "is it wrong to push one fat man onto train tracks in order to stop a trolley from smashing into 5 italian grandmothers?" As AI ethics has become a concern, these problems have suddenly become practical and quantitative. In this talk, I'll present some western liberal ethical principles that are important to algorithmic decision making. I'll provide a number of examples in lending, criminology and education which illustrate how it's impossible to simultaneously satisfy all these ethical principles. If time permits, I'll also discuss how these western principles are far from universal, and how most of the literature on the topic is relatively useless in non-western contexts (e.g., most literature focused on the US takes N=2, I don't even know how to count N in India). - Captured Live on Ustream at ustream.tv/crunch

What people say. Engineers recommend this talk for its rigorous, mathematical framing of the inherent trade-offs in algorithmic fairness.

I was interested in the slide deck and wanted to hear the author expand on some of his thoughts, found a video of his presentation if anyone else is interested. link to this video

On “Who Should Stop Unethical A.I.?”

…ake and eat it too, and it's not the fault of the model you use - the only difference with a human is that they can better hide the factors they use, lie about the influences (perhaps also lie to themselves) and rationalize/invent factors to justify their decision. For this topic, perhaps this talk "AI Ethics, Impossibility Theorems and Tradeoffs" link to this video or its slides link might be interesting for you, it has some flaws but is a decent exploration of the problem space.…

On “New York Regulator Probes UnitedHealth Algorithm for Racial Bias”

…always going to be 'unfair' towards some group of people. The only control we have is who that group of people will be. This is inherent and unavoidable. We need to accept this fact and keep it in consideration when designing such systems (or choosing not to design them in the first place). {procedural fairness, group fairness, utility}. Pick two. link to this video…

On “Why are we using black box models in AI when we don’t need to? (2019)”

…nflate actual bias with political incorrectness. Operational decision making, whether AI or human or statistical, faces an inherent trilemma: it's impossible to simultaneously treat everyone the same way, to have a useful model, and to have uniformly distributed 'bias'-free outcomes. At best a model can strive to achieve two of these factors. See: link to this video 1 link…
