I'm working on a problem which at first sight is similar to classification. The classes are discrete numbers 0-5. The first thought was to use a cross-entropy cost function, but this strips the network from a knowledge that the output classes are related, it's a scale of intensity of a phenomenon on a picture and because of this, the error between 0 and 3 should be bigger than error between 0 and 2.

I thought about: adding one linear layer summing an output from previous layer having 5 binary neurons and using mean square error.

I'm looking for similar problems, papers, tutorials, cost functions. Any suggestions?

Instead of predicting the output like this for, lets say, 4:
[0 0 0 1 0]
I woluld try and encoding like this:
[1 1 1 1 0]

So the model would undestand that it is an increasing and somewhat correlated binary output.

+Mauricio Zuluaga The solution for an always turned on screen when using Xmonad, enjoy.
In Ubuntu it just works, in Xmonad it doesn't, turning the screen off. The inspiration for solution comes from: http://superuser.com/questions/590225/disable-screen-turn-off Checking xset tool in terminal shows smth: xset usa...

#GoogleInbox  is a pretty neat idea, but it lacks one feature which I find crucial: a distraction free compose mode

In an old Gmail I'm able to achieve this by opening a thread in a new tab end switching a browser to full screen mode.

I've sent a feedback, but I don't know if its heard. Just for comparison, Amazon in such case sent me an email with bug id and allow me to "subscribe" to updates on my issue, i.e. if/when they launch the fix/feature they are supposed to sent me an email.

+Tomasz Jurkiewicz feature request? ;-)

hmm ... indeed, no detachable compose window. I'll see if there is any bug about it tomorrow, and then I won't be able to talk about it I guess :-)

Thanks to +Mauricio Zuluaga for sharing:

Xmonad + Ubuntu 14.04 users having issues with Chrome and virtual desktops.

This fixed it for me:

xcompmgr -c &


See https://wiki.archlinux.org/index.php/xcompmgr

and this

https://code.google.com/p/chromium/issues/detail?id=370022
Xcompmgr is a simple composite manager capable of rendering drop shadows and, with the use of the transset utility, primitive window transparency. Designed solely as a proof-of-concept, Xcompmgr is a lightweight alternative to Compiz and similar composite managers.

Some people probably have this problem:
 - have Chrome with 20+ open tabs,
 - PC restart / crash, Chrome is killed unexpectedly
 - PC and Chrome restarted
 - Chrome asks, whether to reopen old tabs, say yes
 - all Google owned websites freeze, gmail/G+ work until Hangouts loads and then die
 - only pkill chrome solves an issue, just closing/opening doesn't work

They should be known as people who cracked Enigma before #WW2 even started.

5 weeks before the war, they transferred the knowledge to British and French agencies which were not able to decrypt Enigma.

Despite many of them being killed by Germans, they've never betrayed and Germans were not aware of Enigma being cracked.

I've read about it first time when was a teenager (12y old) in The Code Book (http://www.amazon.com/Code-Book-Science-Secrecy-Cryptography-ebook/dp/B004IK8PLE/ , I've read the polish edition called "Księga szyfrów"). It was very inspirational story for my future.
The Biuro Szyfrów ([ˈbʲurɔ ˈʂɨfruf] ( listen), Polish for "Cipher Bureau") was the interwar Polish General Staff's agency charged with both cryptography (the use of ciphers and codes) and cryptology (the study of ciphers and codes, particularly for the purpose of "breaking" them).

Hands up if you want more transparency in Brussels!

New deputies are taking their seats in the #EuropeanParliament today after an election that showed action is needed to restore public trust in EU institutions.

Join us in calling on MEPs to sign our anti-corruption pledge at anticorruptionpledge.eu. Share this or post it on your local MEP's wall.
