multiple typedef for same type in c -


i have seen multiple typedef same type in c

typedef struct i_data {     uint32 size;     uint8 *data; } i_data, *i_data_ptr;   typedef i_data i_temp;  typedef i_data *i_temp_ptr;  typedef i_data i_search_temp;  typedef i_data *i_search_ptr;

is possible? how compiler distinguish typedef definition

yes, it's not problem. saying identical.. :)

i_data , i_temp , i_search_temp same thing, typedefs of i_data struct.

i_data_ptr , i_temp_ptr , i_search_ptr same thing, pointers typedef of i_data struct.

if same, in theory why compiler need tell them apart?

it's little person has name , nickname, might not same name it's still same person ;)

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 ...
