| kaushalb09 | hi , could any one tell me where can i get the data to run the example | 00:46 |
|---|---|---|
| @lisitsyn | kaushalb09: git submodule --init update | 00:46 |
| kaushalb09 | thank you | 00:47 |

| kaushalb09 | lisitsyn: could u tell me what type of classification methods you are intending to implement in this gsoc 2013 | 01:00 |
| @iglesiasg | kaushalb09: have you taken a look to GSoC ideas list? | 01:00 |
| kaushalb09 | yeah | 01:01 |
| @iglesiasg | there you have it then ;) | 01:01 |
| @lisitsyn | there is enough info there ;) | 01:01 |

| kaushalb09 | how about implementing swarm optimization techniques | 01:16 |
| @iglesiasg | kaushalb09: like ant colony optimization stuff? | 01:16 |
| kaushalb09 | particle swarm optimization | 01:17 |
| @lisitsyn | kaushalb09: do you have any reference it may be good for that task? | 01:18 |
| @lisitsyn | such meta-heuristics are good for highly non-linear opt problems | 01:19 |
| kaushalb09 | I have personally used it in estimation of software cost | 01:21 |
| kaushalb09 | http://link.springer.com/chapter/10.1007/978-3-642-20573-6_47 | 01:23 |
| @iglesiasg | COCOMO model | 01:24 |
| @iglesiasg | that sounds funny :) | 01:24 |
| kaushalb09 | yeah to calculate the parameters of cocomo model | 01:24 |
| kaushalb09 | constructive cost model | 01:25 |
| kaushalb09 | can that be one of the idea for implementing in GSoC 2013 | 01:41 |
| @iglesiasg | kaushalb09: we would definitely need to describe it more in depth first | 01:44 |
| @iglesiasg | look for a mentor, etc | 01:44 |
| kaushalb09 | i am completely new to GSoC. how do i look for a mentor | 01:49 |
| kaushalb09 | do i need to describe how and what all features should PSO handle | 01:50 |
| @iglesiasg | kaushalb09: you can describe the idea in the mailing list too | 01:52 |
| @iglesiasg | people will give you feedback | 01:52 |

| deerishi | hi | 14:38 |
| deerishi | anyone der? | 14:38 |
| deerishi | i hv been trying 2 solve a bug on kernel pca,https://github.com/deerishi/KernelPCA-test-check/blob/master/KernelPCA.py | 14:39 |
| deerishi | but even if i set the target dimensions to a higher value, m still not getting good results | 14:39 |
| @iglesiasg | deerishi: hey | 14:45 |
| deerishi | hi | 14:46 |
| @iglesiasg | deerishi: why are you setting the target dimension to higher values? | 14:46 |
| deerishi | u told me to implement the sci kit kernel pca example. | 14:46 |
| @iglesiasg | what is the dimension of th einput data? | 14:46 |
| deerishi | input data is 2x100 | 14:46 |
| @iglesiasg | 100 points in 2D | 14:46 |
| deerishi | but if i dont increase the target dimension ,the apply to feature matrix returns a single dimension array,.yes 100 points in 2d | 14:47 |
| @iglesiasg | well | 14:47 |
| @iglesiasg | then, from my scarce knowledge in PCA, I guess that target dimension higher than two doesn't make sense | 14:48 |
| @iglesiasg | lisitsyn: am I wrong? | 14:48 |
| @iglesiasg | lisitsyn: probably yes :) | 14:48 |
| deerishi | yes i am setting it to 2 | 14:48 |
| @iglesiasg | deerishi: mmm ok - what did you mean with higher target dimensions then? :) | 14:48 |
| deerishi | like i said ,by default the target dimensions are being set to 1,which returns a single dimension array | 14:50 |
| @iglesiasg | ok | 14:52 |
| deerishi | the images i am getting are https://github.com/deerishi/KernelPCA-test-check/commit/670ce9dabe334efaac13458dc4648ebd86157799#commitcomment-3052472 | 14:53 |
| deerishi | can advice on where i might be going wrong.i want to solve this bug today | 14:53 |
| deerishi | ? | 14:54 |
| deerishi | ? | 14:59 |
| deerishi | ? | 14:59 |
| @iglesiasg | deerishi: you could compare step by step with other implementation to find out where it is wrong | 15:04 |

| saket | iglesiasg: hi | 15:17 |
| saket | I need to get distance between two SGVector<float> | 15:18 |
| saket | Is 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 #shogun | 15:23 | |
| @iglesiasg | saket: mmm I guess you need CDistance | 15:26 |
| @iglesiasg | check SGVector and Math or Mathematics just in case | 15:26 |
| saket | ohkay | 15:26 |
| saket | so basically each time i need to convert SGVector to CFeatures then init CDistance and then get the distance ... ? | 15:27 |
| @iglesiasg | saket: I don't know, I am not sure what you want to do | 15:28 |
| saket | I am creating a tree for which i need points to be stored in SGVec.. | 15:29 |
| saket | and then I also need distances between them for creating the tree | 15:29 |
| @iglesiasg | yes | 15:30 |
