For example, Bregman divergences are (essentially) all losses that &amp;quot;elicit&amp;quot; the mean of a distribution. If you have any monotone continuous function g(), then |g(x) - g(s)| actually also elicits the median, and these are essentially all that do.&lt;p&gt;Apologies for self-promotion, but you can read more at references on this page (disclaimer: I&amp;#x27;m one of the researchers who posted it): &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;sites.google.com&amp;#x2F;site&amp;#x2F;informationelicitation&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;sites.google.com&amp;#x2F;site&amp;#x2F;informationelicitation&amp;#x2F;&lt;/a&gt;&lt;p&gt;or tutorials on this subject at my blog: &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;bowaggoner.com&amp;#x2F;blog&amp;#x2F;series.html#convexity-elicitation&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;bowaggoner.com&amp;#x2F;blog&amp;#x2F;series.html#convexity-elicitation&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Modes, Medians and Means: A Unifying Perspective</title><url>http://www.johnmyleswhite.com/notebook/2013/03/22/modes-medians-and-means-an-unifying-perspective/</url></story>
