wuweihey i would like to discuss about CFeatures12:34
wuweisee https://gist.github.com/vinx13/65d9912cdb90c05e28fe85b095b7340f#refactor-non-const-methods-of-features12:34
wuweithe problem is, get_feature_vector cannot be const right now12:35
wuweibecause it may compute on the fly and then cache it12:35

@wikingwuwei, hello14:31
@wikingstill here?14:31
@wikingsorry i was out till now14:31
@wikingyeah14:31
@wikingbuuut14:31
@wikingwe can make it cache14:31
@wikingi mean const14:31
@wikingand you make the cache mutable14:31
@wikingit's a bit ugly14:31
wuweihi wiling14:31
wuweihi wiking14:32
wuweiyeah, we can make it mutable14:33
wuweicache is not thread safe, not sure whether it's a problem14:33
wuweiactually there is data race, when we access features concurrently14:44
wuweifor example, in parallel xvalidation14:44
@wikingwuwei, ahahh yeah14:45
@wikingi know :)14:45
@wikingxval is totally not threadsafe14:45
@wikingwhich is of course a major problem14:45
-!- Jinquan [dd0628c2@gateway/web/freenode/ip.221.6.40.194] has joined #shogun14:46
@wikingbut again that is easily solvable by some locks :P14:47
@wikingwe have an abstraction over locks14:48
@wikingbut actually you could just use std::mutex14:48
@wiking:P14:48
wuweiyeah, great!14:48
wuweiwe can use locks in cache14:49
@wikingindeed14:51
@wikingCLock is an easy way to just add locks to the whole thing14:51
