I interpreted this comic completely differently than what is written in the explanation (though I can agree that the explanation as written is plausible).  When I first read the comic, I assumed Megan and Cueball were hesitant to have guests come over because they would have to clean up after the guests left.  Presumably their house would be spotlessly neat and tidy after more than a year of no visitors, and having someone visit would spoil that.  Speaking personally, it will be great to have guests staying with me again, but there is a twinge of regret that the much simpler and easy pace of pandemic life is over now that I’m vaccinated.[[Special:Contributions/172.70.110.170|172.70.110.170]] 04:21, 22 June 2021 (UTC)&lt;br /&gt;
:I can see what you mean, but if you also read the title text is it clear that it is their house that is not clean enough for guest. I can totally relate. We always get the house tidy when we invite guest over, and apart from very close family, which do not need this tidiness, we have not had any visitors for over a year... It is thus for sure the problem that the house is a mess, and they have got used to live in this since no one came around to look at it. But now, if they wish to have friends over, they have to make a big effort to not be embarrassed. And having gotten used to not seeing people the effort may bot be worth it (obviously). --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:53, 22 June 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Regarding the title text, the explanation reads, &amp;quot;. . . and assumes that this is an assignment of one state from the other that is commutative (i.e. reversible) from the simplistic idea of readiness arising from status.&amp;quot; Can someone translate this for me, please? I've only completed two years of college English, so it baffles me! [[Special:Contributions/162.158.74.117|162.158.74.117]] 11:12, 22 June 2021 (UTC)&lt;br /&gt;
:Not sure it's the right word, but a function &amp;quot;A =&amp;gt; B&amp;quot; (read that as 'leads to', 'produces', 'implies', etc) need not imply &amp;quot;B =&amp;gt; A&amp;quot; (commutative functions, such as matrix multiplication, also give different results depending upon the order attempted).&lt;br /&gt;
:In reality, &amp;quot;House Readiness &amp;lt;= Vaccination Status + Pre-Pandemic Standards&amp;quot; (reversing the cause/effect sides) so &amp;quot;Vaccination Status =&amp;gt; House Readiness&amp;quot; is already wrong, without even considering how the accepted nature of Vaccinatedness is not going to change between rooms (unless your house crosses a state boundary/whatever, with different enforcements?&lt;br /&gt;
:I'd have explained it differently from the start. Maybe the typical programming confusion between equality and assignment operators, and why it's good practice to habitually produce intended boolean outputs from &amp;quot;CONST equ VAR&amp;quot; (however the code dialect demands) rather than the other way round, for the compiler to catch accidental assignments/non-comparisons, that you may have mis-typed, from the off - but that could be even more confusing for readers. ;) [[Special:Contributions/141.101.99.177|141.101.99.177]] 12:13, 22 June 2021 (UTC)&lt;br /&gt;

&amp;quot;2020-21 pandemic of the SARS-CoV-2 virus&amp;quot;. I like the optimism that the pandemic will be over in 2021. 😁&lt;br /&gt;

&lt;div&gt;the source of title text maybe is Szeliski, ''Computer Vision: Algorithms and Applications'' (2010), p. 10. --[[User:Valepert|valepert]] ([[User talk:Valepert|talk]]) 06:59, 24 September 2014 (UTC)&lt;br /&gt;

[http://www.wired.com/2012/06/google-x-neural-network/ Google’s Artificial Brain Learns to Find Cat Videos] might be useful as a description of the problem [[Special:Contributions/108.162.250.219|108.162.250.219]] 08:34, 24 September 2014 (UTC)&lt;br /&gt;

Isn't there an xkcd where the estimate of 5 years of work is equivalent to &amp;quot;might take forever?&amp;quot; [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 13:16, 24 September 2014 (UTC)&lt;br /&gt;
:I'm pretty sure you're refering to 678. [[Special:Contributions/173.245.52.132|173.245.52.132]] 15:00, 25 September 2014 (UTC)&lt;br /&gt;

The link in the description is to a document by {{w|Seymour Papert}} and the [http://books.google.com/books/about/The_Summer_Vision_Project.html?id=qOh7NwAACAAJ book] on the project is also by Papert.  Is there any contemporary evidence that it was actually Minsky who assigned the project?  I think he just got interested in it later. 14:17, 24 September 2014 (UTC)&lt;br /&gt;

Is it possible that Randall's selection of bird rather than another naturally occurring object is a subtle reference to the Birdsnap app (http://engineering.columbia.edu/it-crow-or-raven-new-birdsnap-app-will-tell-you-0) which has solved some of the aspects of this problem?

Hopefully I can add that this also seems to make reference to the U.S. Forest Service intention to make everyone have a permit to take pics, etc., in national parks.  https://www.yahoo.com/travel/dont-take-that-picture-the-u-s-forest-service-might-98484656432.html {{unsigned ip|108.162.216.21}}&lt;br /&gt;

Post the picture to an online forum, say it's a bird, if it's not everyone will correct you as per http://xkcd.com/386/, so scrape forum and if there's a lot of attention it's not a bird, if there isn't much attention it probably is a bird.

A dev team at Flickr took this comic as a challenge, and set up a PoC at http://parkorbird.flickr.com/ (that seems to work fairly well). --[[Special:Contributions/108.162.210.135|108.162.210.135]] 20:08, 20 October 2014 (UTC)&lt;br /&gt;

A 'picture of a bird' from a CS perspective is a reverse engineering problem.  The picture is a 2 dimensional rendering of a 3-dimensional world and a 'bird' is a 3-dimensional object.  It takes years for the mind of a newborn human to be able to recognize a majority of objects based on their 'first look' at a stereoscopic (two-eyes) image presented by their visual cortex.  The software equivalency of this would be to create a 3 dimensional representation of objects and create a linear-algebra algorithm that can define the statistical probability that any given shape is within a certain degree of exclusion a matrix representation of the target shape (area) of the 3 dimensional object (bird) based on distance (using spacial reconstruction).  It's not impossible, it's just really really hard.  - nerd answer {{unsigned ip|173.245.54.166}}&lt;br /&gt;
:To be honest I don't think it is impossible to replicate any function of human intelligence and mental capacity on a computer system. It just requires sufficient processing ability, appropriate hardware, and of course, an understanding of how humans do it in the first place. -Pennpenn [[Special:Contributions/108.162.250.162|108.162.250.162]] 03:29, 17 September 2015 (UTC)&lt;br /&gt;
