How does word co-occurrence let two words from the same topic link together in LDA topic model?
Topic models and word co-occurrence methods
When using the Profile Tool plugin I get a graph that looks like the 2nd derivative of what I want. That is, it looks like the rate of change of the slope of the elevation profile. I just want the elevation profile! The data is present for good 1' contour lines. Why is the Profile Tool interpreting the data in such a bizarre way? What am I missing? And what are the Min and Max units? File upload with Javascript without user intervention Using single quote by curly braces in String.format in Dynamic SOQL I'm struggling to use String.format to replace a token with a value when the token is within single quotes:  Example:  String query = String.format('SELECT Id FROM Availability WHERE Person__c = \'{0}\'', personId);   String query is equal to:  SELECT Id FROM Availability WHERE Person__c = {0}   Rather than:  SELECT Id FROM Availability WHERE Person__c = '234567890' How come I can't give more than 500 rep? Why can't I give more than 500 reputation as a bounty at a time? The system won't let me choose an option more than 500.  Also, how were some users able to do so? On  the OP has given a single bounty worth 550 rep, but at the moment I have 844 rep and I can't give any more than 500 rep on a bounty.  Can you please tell us if this is a bug or not? Should edits with only minor code improvements be accepted. As an example, I'm reviewing an edit that changes all double quotes to single quotes and renames a variable in some javascript. With the exception of the variable rename (which is not entirely necessary), the edit is frivolous. Should I accept on the merits of a debatable variable name change? Keytool Signing Problem: Keystore was tampered with, or password was incorrect What do you call all the pieces of a song minus the lyrics I think there must be a good word for this, but can't think of what it might be.  Harmony and Melody are pieces of it, beat seems simplistic, Instrumentation seems too scientific and dull.  Any Ideas? How we can show every permutation is either even or odd,but not both......I can't arrive at a proof for this ..... Can anybody give me the proof...  Thanks in advance... There are a lot of software in Windows to merge PDF files but how can we do the same in Ubuntu? Why isn't sizeof for a struct equal to the sum of sizeof of each member? Is there a way to draw a sort of connection between subplots in TiKz/pgfplot, like in this ? I'm looking to achieve something like this:    But I would need to draw the "x 2000" line between the plots.

In this example  \documentclass{article} \usepackage[breaklinks]{hyperref} \begin{document} \url{http://www.emarketer.com/blog/index.php/quick-stat-smartphone-users-account-38-mobile-phone-users/} \end{document}   PdfLaTeX won't break the URL and create a too long line. However, if I replace \url with \href like this:  \documentclass{article} \usepackage{hyperref} \begin{document} \href{http://www.emarketer.com/blog/index.php/quick-stat-smartphone-users-account-38-mobile-phone-users/}{http://www.emarketer.com/blog/index.php/quick-stat-smartphone-users-account-38-mobile-phone-users/} \end{document}   I get the line broken, but the font of the link is not right any more of course (normal instead of texttt). Why doesn't URL break the line at dashes and what could I do to get a nicely typeset line-broken link? Stack Overflow interesting questions implementation According to the tooltip of the 'interesting' tab, interesting questions are     "questions that may be of interest to you based on your history and tag preferences"   Does Stack Overflow use a recommendation engine or just some sql sort/filter? How do I programmatically get the field type of a specific field? Can I sell starting gear in Adventurers League play? I'm starting a new AL game (as a player) and I have a question that's not addressed in the AL material.  According to Adventurers League Player's Guide (page 4)     When you create your D&amp;D Adventurers League character for the current season, take starting equipment as determined by your class and background. You cannot roll for your starting wealth.   Meaning I can't start with whatever I want. However, I am playing a ranged-focused fighter, so the second gear option is of no use to me:   (a) a martial weapon and a shield or (b) two  martial weapons   Can I choose any two martial weapons and sell them for half price to use for purchasing other gear before play? And is there a restriction on how much gold I can get?  For example, two hand crossbows (martial ranged weapons) can net me 75 gp when sold, or two greatswords nets me 50 gp when sold. Which is right: "In one of the computers" or "On one of the computers"? Changing the homepage Installed memory 4GB but only 1.93 GB is usable shows in system properties dialog? In my Intel Core i5 2.80 GHz CPU , DH55HC series Intel mother board machine installed with windows 7 64 bit  machine, when I right click my computer and see system properties I see that "Installed Memory(RAM): 4 GB(1.93 usable)".I have 2 x 2 GB DDR 3 RAM modules.  I have verified, * Two of RAM modules are working * Two of RAM slots in mother board are working   What are the cause(s) for this might be to look next ie: what settings in BIOS etc ? I shifted to Ubuntu 10.10 now I am facing problem to have C/C++ compiler. What are the possible ways so that I can use C/C++ compiler using all the libraries (like graphic, math, conio, stdlib, etc) as in Microsoft Windows creating executable file? What does the tilde before a function name mean in C#?
