| uricamic | hi n4nd0 | 09:32 |
|---|---|---|
| -!- cronor [~cronor@g230120109.adsl.alicedsl.de] has quit [Quit: cronor] | 09:38 | |
| n4nd0 | uricamic: hey | 09:40 |
| uricamic | n4nd0: when do you think your changes in SO framework will be pulled to shogun? I want to write a simple example using the BMRM solver, but I think it will be better to do this after your new changes will be accepted | 09:42 |
| n4nd0 | uricamic: I am not completely sure, I did the pull request and sonney2k told me to make some changes, they were not very important though | 09:43 |
| n4nd0 | the problem is that currently my multiclass example doesn't work good | 09:44 |
| uricamic | n4nd0: any ideas what could be wrong? | 09:44 |
| n4nd0 | not many, just that there must be a bug somewhere | 09:45 |
| uricamic | in the solver? | 09:45 |
| n4nd0 | I guess so | 09:46 |
| n4nd0 | there is a thing that bugs me a bit | 09:46 |
| n4nd0 | right now I use the same data for training and testing | 09:46 |
| n4nd0 | just to make it easier | 09:46 |
| uricamic | ok | 09:47 |
| n4nd0 | and all the examples of one class are classified as another class | 09:47 |
| n4nd0 | but still, the values of the slacks after training for those examples are 0 | 09:47 |
| n4nd0 | I think that tells me that something is going wrong | 09:48 |
| uricamic | so the classes are swapped? | 09:48 |
| n4nd0 | not really | 09:48 |
| n4nd0 | it is that some of the classes used for training are never classified | 09:49 |
| uricamic | I see | 09:49 |
| n4nd0 | I going to compare now how the weight vectors learned in so and in one-vs-rest look like | 09:51 |
| n4nd0 | I expect that they should be somewhat similar | 09:51 |
| uricamic | yep | 09:54 |
| uricamic | and you are now working on multiclass example with how many classes? | 09:54 |
| n4nd0 | I change the number of classes as a parameter | 09:56 |
| n4nd0 | I am focusing more in three because for two classes looks generally ok | 09:56 |
| uricamic | so for 2 classes it works and the problem is only when the number of classes is >2 ? | 09:57 |
| n4nd0 | yes, apparently | 10:00 |
| uricamic | I see, that is somehow strange | 10:02 |
| uricamic | do you have the source codes for this pushed in your fork of shogun? | 10:03 |
| n4nd0 | yes | 10:03 |
| n4nd0 | let me give you the link | 10:04 |
| n4nd0 | https://github.com/iglesias/shogun/blob/so/src/shogun/so/PrimalMosekSOSVM.cpp | 10:04 |
| n4nd0 | there in train_machine | 10:04 |
| uricamic | thanks, I will look at it | 10:05 |
| n4nd0 | https://github.com/iglesias/shogun/blob/so/src/shogun/so/MulticlassModel.cpp | 10:05 |
| n4nd0 | and also in the mathematics/mosek methods used | 10:05 |

| n4nd0 | uricamic: hey, how is it going? | 14:57 |
| uricamic | n4nd0: hi | 14:57 |
| uricamic | I have looked on your code, but haven't found anything wrong | 14:58 |
| uricamic | but I haven't found the example putting things together | 14:58 |
| uricamic | have you commited it to your fork on github? | 14:59 |
| n4nd0 | no | 14:59 |
| n4nd0 | I am going to do that now | 14:59 |
| uricamic | ok | 15:00 |
| n4nd0 | uricamic: did you find something that looked weird or you didn't really get it=? | 15:00 |
| uricamic | in the MulticlassModel everything looked clear | 15:00 |
| uricamic | I will try to combine your up-to-date version of the SO framework and produce the example with the BMRM method and then to compare your solver with mine | 15:02 |
| n4nd0 | ok | 15:03 |
| n4nd0 | about the example | 15:03 |
| n4nd0 | if you would like to test it in your machine, note that you need mosek for that | 15:03 |
| n4nd0 | and to use mosek within shogun you'd have to change by hand some parameters in your .config | 15:04 |
| n4nd0 | but I don't think you really need to test it | 15:04 |
| uricamic | ok | 15:04 |
| n4nd0 | I mean, you have done enough taking a look to the core ;) | 15:04 |
| n4nd0 | code* | 15:04 |
| uricamic | but maybe then it will be easier to locate the source of the problem | 15:05 |
| n4nd0 | ok, as you like | 15:06 |
| n4nd0 | in any case, if you plan to run it, just tell me to describe you what parameters you need to change to make it run | 15:06 |
| uricamic | ok | 15:07 |
| uricamic | first I will have to get my solver working | 15:07 |
| n4nd0 | sure | 15:08 |
