| foulwall_ | damn, finally got shogun compiled... I resized the swap to 8GB... | 12:54 |
| @lisitsyn | foulwall_: haha sorry that's due to heavy templating I guess | 12:55 |
| foulwall_ | lisitsyn: haha, I'm wondering why the same thing works well on gentoo. | 12:57 |
| @lisitsyn | foulwall_: what's the compiler on gentoo? | 12:57 |
| @lisitsyn | 4.7 I guess? | 12:57 |
| foulwall_ | lisitsyn: I forgot. | 12:57 |
| @lisitsyn | foulwall_: I expect gentoo is newer so better compiler | 12:58 |
| 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 |
| @lisitsyn | ahh I see | 13:00 |
| @lisitsyn | no idea then | 13:00 |
| @lisitsyn | :) | 13:00 |
| foulwall_ | lisitsyn: anyway I can begin my data integration work. I'll ask sonney2k first... | 13:02 |

| vgorbati | Is there anybody who can answer the questions about CKernel class? | 15:07 |
| @lisitsyn | vgorbati: yes | 15:12 |
| vgorbati | lisitsyn: 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 |
| @lisitsyn | vgorbati: IIRC free_feature_vector for DenseFeatures is just NOP | 15:14 |
| @lisitsyn | does nothing at all | 15:14 |
| @lisitsyn | but actually it should be there | 15:15 |
| vgorbati | lisitsyn: so, 'get_feature_vector' for DenseFeatures just returns pointer to the corresponding column, without allocating extra memory? | 15:15 |
| vgorbati | lisitsyn: as I see, there is some code in free_feature_vector | 15:17 |
| vgorbati | lisitsyn: 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 needed | 15:22 |
| vgorbati | lisitsyn: 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 | |
| @lisitsyn | vgorbati: which function? | 15:29 |
| @lisitsyn | vgorbati: it's kind of legacy actually | 15:31 |
| @lisitsyn | it was uglier before | 15:31 |
| vgorbati | lisitsyn: so, which version should be used: the one that returns SGVector, or the one that returns pointer to column? | 15:33 |
| @lisitsyn | vgorbati: SGVector is ok | 15:33 |
| vgorbati | lisitsyn: 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 |
| vgorbati | lisitsyn: it will get this vectors, and then call some inner routine | 15:36 |
| vgorbati | lisitsyn: and this routine will be overriden in classes, inherited from this intermediate class | 15:36 |
| @lisitsyn | vgorbati: sounds good | 15:36 |
| vgorbati | lisitsyn: the only question is how to name this intermediate class:) | 15:37 |
| @lisitsyn | vgorbati: CDenseDotKernel maybe | 15:38 |
| vgorbati | lisitsyn: ok, will use that. Then I'll try this out, if you don't mind? | 15:38 |
| @lisitsyn | I don't mind at all :) | 15:39 |

| @lisitsyn | vgorbati: yes | 16:33 |
| vgorbati | lisitsyn: 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 |
