kaushalb09hi , could any one tell me where can i get the data to run the example00:46
@lisitsynkaushalb09: git submodule --init update00:46
kaushalb09thank you00:47

kaushalb09lisitsyn: could u tell me what type of classification methods you are intending to implement in this gsoc 201301:00
@iglesiasgkaushalb09: have you taken a look to GSoC ideas list?01:00
kaushalb09yeah01:01
@iglesiasgthere you have it then ;)01:01
@lisitsynthere is enough info there ;)01:01

kaushalb09how about implementing swarm optimization techniques01:16
@iglesiasgkaushalb09: like ant colony optimization stuff?01:16
kaushalb09particle swarm optimization01:17
@lisitsynkaushalb09: do you have any reference it may be good for that task?01:18
@lisitsynsuch meta-heuristics are good for highly non-linear opt problems01:19
kaushalb09I have personally used it in estimation of software cost01:21

@iglesiasgCOCOMO model01:24
@iglesiasgthat sounds funny :)01:24
kaushalb09yeah to calculate the parameters of cocomo model01:24
kaushalb09constructive cost model01:25
kaushalb09can that be one of the idea for implementing in GSoC 201301:41
@iglesiasgkaushalb09: we would definitely need to describe it more in depth first01:44
@iglesiasglook for a mentor, etc01:44
kaushalb09i am completely new to GSoC. how do i look for a mentor01:49
kaushalb09do i need to describe how and what all features should PSO handle01:50
@iglesiasgkaushalb09: you can describe the idea in the mailing list too01:52
@iglesiasgpeople will give you feedback01:52

saket I have one techinical query too ...13:26
saketI need to find distance between a SGVector<float64_t> and an index in rhs of CDistance13:26
saketSo, is the only way to do this is by replacing the lhs of CDistance, right? or is there a better/cleaner/smart work around ?13:27

deerishihi14:38
deerishianyone der?14:38
deerishii hv been trying 2 solve a bug on kernel pca,https://github.com/deerishi/KernelPCA-test-check/blob/master/KernelPCA.py14:39
deerishibut even  if  i set the target dimensions to a higher value, m still not getting good results14:39
@iglesiasgdeerishi: hey14:45
deerishihi14:46
@iglesiasgdeerishi: why are you setting the target dimension to higher values?14:46
deerishiu told me to implement the sci kit kernel pca example.14:46
@iglesiasgwhat is the dimension of th einput data?14:46
deerishiinput data is 2x10014:46
@iglesiasg100 points in 2D14:46
deerishibut if i dont increase the target dimension ,the apply to feature matrix returns a single dimension array,.yes 100 points in 2d14:47
@iglesiasgwell14:47
@iglesiasgthen, from my scarce knowledge in PCA, I guess that target dimension higher than two doesn't make sense14:48
@iglesiasglisitsyn: am I wrong?14:48
@iglesiasglisitsyn: probably yes :)14:48
deerishiyes i am setting it to 214:48
@iglesiasgdeerishi: mmm ok - what did you mean with higher target dimensions then? :)14:48
deerishilike i said ,by default the target dimensions are being set to 1,which returns a single dimension array14:50
@iglesiasgok14:52
deerishithe images i am getting are https://github.com/deerishi/KernelPCA-test-check/commit/670ce9dabe334efaac13458dc4648ebd86157799#commitcomment-305247214:53
deerishican advice on where i might be going wrong.i want to solve this bug today14:53
deerishi?14:54
deerishi?14:59
deerishi?14:59
@iglesiasgdeerishi: you could compare step by step with other implementation to find out where it is wrong15:04

saketiglesiasg: hi15:17
saketI need to get distance between two SGVector<float>15:18
saketIs there a way to do it instead making a CDistance object each time ?15:18
-!- vgorbati [d4029f22@gateway/web/freenode/ip.212.2.159.34] has joined #shogun15:23
@iglesiasgsaket: mmm I guess you need CDistance15:26
@iglesiasgcheck SGVector and Math or Mathematics just in case15:26
saketohkay15:26
saketso basically each time i need to convert SGVector to CFeatures then init CDistance and then get the distance ... ?15:27
@iglesiasgsaket: I don't know, I am not sure what you want to do15:28
saketI am creating a tree for which i need points to be stored in SGVec..15:29
saketand then I also need distances between them for creating the tree15:29
