@sonney2khushell, I am just going through some warnings - could you please document /home/buildslave/deb3_-_modular_interfaces/build/src/shogun/multiclass/MulticlassStrategy.h:148: warning: argument 'sig_params' of command @param is not found in the argument list of shogun::CMulticlassStrategy::rescale_outputs(SGVector< float64_t > outputs, const SGVector< float64_t > As, const SGVector< float64_t > Bs)?08:25

foulwall_damn, finally got shogun compiled... I resized the swap to 8GB...12:54
@lisitsynfoulwall_: haha sorry that's due to heavy templating I guess12:55
foulwall_lisitsyn: haha, I'm wondering why the same thing works well on gentoo.12:57
@lisitsynfoulwall_: what's the compiler on gentoo?12:57
@lisitsyn4.7 I guess?12:57
foulwall_lisitsyn: I forgot.12:57
@lisitsynfoulwall_: I expect gentoo is newer so better compiler12:58
foulwall_lisitsyn: I haven't updated gentoo for about a year... I got tired of fixing the dependency... There must have some tricky thing in it....13:00
@lisitsynahh I see13:00
@lisitsynno idea then13:00
@lisitsyn:)13:00
foulwall_lisitsyn: anyway I can begin my data integration work. I'll ask sonney2k first...13:02

vgorbatiIs there anybody who can answer the questions about CKernel class?15:07
@lisitsynvgorbati: yes15:12
vgorbatilisitsyn: in this file https://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/kernel/LinearARDKernel.cpp in 'compute' method there are no 'free_feature_vector' calls, won't this lead to memory leaks, will it?15:13
@lisitsynvgorbati: IIRC free_feature_vector for DenseFeatures is just NOP15:14
@lisitsyndoes nothing at all15:14
@lisitsynbut actually it should be there15:15
vgorbatilisitsyn: so, 'get_feature_vector' for DenseFeatures just returns pointer to the corresponding column, without allocating extra memory?15:15
vgorbatilisitsyn: as I see, there is some code in free_feature_vector15:17
vgorbatilisitsyn: I got it, the overloaded version of get_feature_vector is called there - the one that returns SGVector, and SGVector should release the memory if needed15:22
vgorbatilisitsyn: btw, why don't other kernels that work in a similar manner use this overloaded function, that handles memory problems?15:26
-!- foulwall [~foulwall@li379-21.members.linode.com] has quit [Ping timeout: 245 seconds]15:29
@lisitsynvgorbati: which function?15:29
@lisitsynvgorbati: it's kind of legacy actually15:31
@lisitsynit was uglier before15:31
vgorbatilisitsyn: so, which version should be used: the one that returns SGVector, or the one that returns pointer to column?15:33
@lisitsynvgorbati: SGVector is ok15:33
vgorbatilisitsyn: ok. I have noticed, that some kernels follow a similar pattern: they get idx_a and idx_b vectors and then they compute the kernel value using this vectors. What if I add an intermediate class (inherited from CDotFeatures), that overrides 'compute' method:15:36
vgorbatilisitsyn: it will get this vectors, and then call some inner routine15:36
vgorbatilisitsyn: and this routine will be overriden in classes, inherited from this intermediate class15:36
@lisitsynvgorbati: sounds good15:36
vgorbatilisitsyn: the only question is how to name this intermediate class:)15:37
@lisitsynvgorbati: CDenseDotKernel maybe15:38
vgorbatilisitsyn: ok, will use that. Then I'll try this out, if you don't mind?15:38
@lisitsynI don't mind at all :)15:39

vgorbatilisitsyn: still there?16:33
@lisitsynvgorbati: yes16:33
vgorbatilisitsyn: some string kernels follow the same pattern as well - https://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/kernel/string/PolyMatchStringKernel.cpp#L63 ... Should I also try to subclass them from the intermediate class?16:34
@lisitsynvgorbati: if this reduces LoC - yes16:35
