iphone - Whats the difference between saving content at document directory or temp folder? -


i want save multipel photos in application, application run in background. main difference between saving photos in doc dir or temp path.

and suggest me best way save photos

  1. document dir
  2. temp folder
  3. nsuserdefaults

thanks in advance

the main difference path: <sandbox>/documents or <sandbox>/tmp.

some more differences:

  1. the documents directory can accessed via itunes if app has file sharing enabled.

  2. the contents of tmp directory volatile, os free purge in order save space.

about nsuserdefaults: that's different, it's mechanism stores app-specific configuration data in property lists, can't imagine how and/or why use storing images.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
