  • Neural Network: Handling unavailable inputs (missing or incomplete data)

    - by Mike
    Hopefully the last NN question you'll get from me this weekend, but here goes :) Is there a way to handle an input that you "don't always know"... so it doesn't affect the weightings somehow? Soo... if I ask someone if they are male or female and they would not like to answer, is there a way to disregard this input? Perhaps by placing it squarely in the centre? (assuming 1,0 inputs at 0.5?) Thanks

  • Cache Auth Tokens (or Caching HTTP headers in General) - Best Practices

    - by viatropos
    I'm using the Ruby GData Library to access Google Docs and I recently got the GData::Client::CaptchaError because I was re-logging in with every request. Reading this post, it recommends not logging in with every request, but caching the authentication token. How do I go about doing that correctly? Google says it expires every 24 hours, and it doesn't seem like I should store it in the session, so what should I do? I'm using Ruby on Rails with all this. Thanks so much

    Hi, I'm using the Jquery plugin Address to achieve deep linking. The generated urls come out in the format www.example.com/#/tab/image, but what I need is www.example.com/#tab/image.

  • Stop execution of python script when parent Bash shell script is killed

    - by jrdioko
    I'm working on a Bash shell script that runs several Python scripts like so: cd ${SCRIPT_PATH} python -u ${SCRIPT_NAME} ${SCRIPT_ARGS} >> $JOBLOG 2>&1 At one point, I killed the shell script (using kill PID), but the Python script continued running, even after the script terminated. I thought these would die as soon as the main script died. What am I misunderstanding about Bash scripting, and what can I do to get the functionality I'm looking for? Thanks in advance!

  • sudo taking long time

    - by Sam
    On a Ubuntu 9 64bit Linux machine, sudo takes longer time to start. "sudo echo hi" takes 2-3 minutes. strace on sudo tells poll("/etc/pam.d/system-auth", POLLIN) timesout after 5 seconds and there are multiple calls(may be a loop) to same system call (which causes 2-3min delay). Any idea why sudo has to wait for /etc/pam.d/system-auth? Any tunable to make sudo to timeout faster? Thanks Samuel
