Question about #DecisionTheory and #Statistics — in elementary decision theory we usually call the basic possible ‘outcomes of nature’ ‘states of nature’. Eg ‘rain’ ‘no rain’ in deciding to take an umbrella. However in statistical decision theory (a la Wald’s formulation) we usually reserve the term ‘state of nature’ for a probability distribution over such outcomes 1/2

Just have been made aware that today is the 120th #birthday of Frank Ramsey: https://plato.stanford.edu/entries/ramsey/ #philosophy #decisiontheory

You have a problem: you currently pick thresholds for model-based actions using some arbitrary heuristic.

Your solution: pick the threshold that maximizes expected utility (e.g. revenue, profit, ROI, …) instead. That’s the definition of the rational decision, right?

Hmm, for some reason you now seem to have several more problems.

ETHICS. New book explores complicity, or being involved in the harmful wrong-doing of others, either through action (helping, allowing, or encouraging) or inaction (silence or not preventing). Two useful distinctions: “bounded ethicality,” or the limits to the information we have to behave ethically; and “bounded awareness,” our finite capacity to notice all that’s happening around us. From author of Better, Not Perfect (2020) about sense of realistic ethical standards.

"Functional Decision Theory: A New Theory of Instrumental Rationality" by Yudkowsky and Soares

:arxiv: https://arxiv.org/abs/1710.05060

A fascinating paper introducing a new decision theory which solves many problems found on Causal Decision Theory and Evidential Decision Theory.

The idea behind FDT is to fix one's decision process as the output of a fixed mathematical function which answer the question "Which output of this very function would yield the best outcome?"

Ahhh I'm doing it, I'm finally doing it! Here's my #introduction + first toot:

I'm an Assistant Professor and health economist at #UMass-Amherst. I apply #decisiontheory to #healthcare -- basically, I try to understand how physicians make decisions for patients and how these decisions can be improved.

I like canines, coffee, cooking, and cocktails. Also everything fantasy-related (books/movies/ video games).

OK, time for a proper #introduction

I am an #economist, with interests in (mostly dynamic) #gametheory and #decisiontheory. But I dabble in other things as well.

I am very interested in the interface between Economics and #CS, though I have yet to produce meaningful work there...

I use #tex for my writing; #lyx too sometimes. A few years ago I wrote the LaTeXtools plugin for the Sublime Text editor, with help from many contributors of course. Others are now carrying the torch!
