| KMcQuisten | Where was it getting caught up? | 00:01 |
|---|---|---|
| blackburn | hmmm something strange here.. | 00:05 |
| blackburn | KMcQuisten: funny thing x2 factor comes from the code, but not two feature instances.. | 00:05 |
| KMcQuisten | Really? I wonder if it's pulling them from the initialized kernels | 00:06 |
| blackburn | yeah.. | 00:07 |
| KMcQuisten | I tired a CombinedFeature and CombinedKernel with StringChar features and WD kernels of 2 different orders and got the same sort of error as with the StringWordFeatures | 00:12 |
| KMcQuisten | SystemError: [ERROR] assertion char_vec && len>0 failed in file kernel/WeightedDegreeStringKernel.cpp line 522 | 00:12 |
| blackburn | different error | 00:13 |
| KMcQuisten | Yes, but still failing the check to see if the proper number of features are present | 00:13 |
| KMcQuisten | The same thing happens when I combine a WD kernel on StringChar features with a CommWOrdString kernel on StringWord features. | 00:15 |
| KMcQuisten | Like you, I hae stringChar+Real and StringWord + real working fine | 00:16 |
| blackburn | heh | 00:17 |
| KMcQuisten | Somethign about this doesn't like having multiple kinds of string features in a CombinedKernel | 00:17 |
| KMcQuisten | Very strange | 00:17 |
| blackburn | does it happen with real+real? | 00:17 |
| KMcQuisten | Let me check quicklty | 00:18 |
| blackburn | hmm it happens with real+string now | 00:20 |
| KMcQuisten | Real and Real worked for me | 00:21 |
| KMcQuisten | Real and StringWord work for me | 00:21 |
| KMcQuisten | Let me check Real and StringChar | 00:21 |
| KMcQuisten | Real and StringChar work for me with a WD kernel | 00:24 |
| KMcQuisten | ONly thing that fials for me is combining multibple string features | 00:24 |
| KMcQuisten | man my typing is crap today. | 00:25 |
| blackburn | heh | 00:25 |
| KMcQuisten | Need more sleep :) | 00:25 |
| blackburn | no problem | 00:25 |
| blackburn | okay but real + string fails now too | 00:25 |
| blackburn | real+real works | 00:27 |
| KMcQuisten | Not for me. Real + string still works for me | 00:28 |
| KMcQuisten | real + real works for me, too | 00:28 |
| KMcQuisten | I set it up real + string and string + real. Both work | 00:28 |
| blackburn | ok more or less it is clear now | 00:29 |
| blackburn | I'll dig into the code again | 00:29 |
| KMcQuisten | what's the verdict? | 00:29 |
| KMcQuisten | Allrighty | 00:29 |
| KMcQuisten | Ok, i'm going ot head out of here. When you have news feel free to let me know on the mailing list. | 00:33 |

| pluskid | blackburn: do you know how to clone a VowpalWabbitMachine? | 11:29 |
| blackburn | a=b.clone()? | 11:29 |
| pluskid | is there such a method? | 11:29 |
| blackburn | I don't think so | 11:29 |
| pluskid | hmm, too bad | 11:30 |
| pluskid | I want to have a copy of a VWMachine somewhere | 11:30 |
| blackburn | add a copy constructor :) | 11:30 |
| pluskid | seems I have to construct the copy manually | 11:30 |
| pluskid | to do that then I should have to understand the implementation of VW first | 11:30 |
| pluskid | btw: since shogun has a generic serialization component, I guess it should not be too difficult to build a generic clone component based on that | 11:31 |
| blackburn | virtual clone method? | 11:32 |
| pluskid | I'm not sure, but I guess it could be implemented in a similar way to serialization | 11:34 |
| -!- n4nd0 [~nando@s83-179-44-135.cust.tele2.se] has quit [Quit: leaving] | 11:34 | |
| pluskid | for example, a *very naive* way is to serialize it to some where and then de-serialize, we get a clone ... | 11:34 |
| blackburn | I don't mind actually if somebody do that :) | 11:36 |
| pluskid | :D | 11:37 |

| KMcQuisten | Hello all | 23:00 |
| blackburn | hey | 23:00 |
| KMcQuisten | Get my email? | 23:00 |
| blackburn | which one? | 23:00 |
| KMcQuisten | most recent. sent today | 23:01 |
| KMcQuisten | moments ago, inf act | 23:01 |
| blackburn | ah right I just sent an answer | 23:01 |
| blackburn | 10 mins ago I guess | 23:01 |
| KMcQuisten | well then let me look | 23:01 |
| blackburn | ok I suggested to turn off linadd at all | 23:01 |
| KMcQuisten | ok let me check | 23:02 |
| -!- heiko [~heiko@109.144.207.254] has joined #shogun | 23:05 | |
| blackburn | it can be that linadd is a little broken | 23:06 |
| KMcQuisten | Looks like tha'ts the case. It works with LINADD disables | 23:07 |
| KMcQuisten | d | 23:07 |
| wiking | blackburn: tomorrow | 23:10 |
| blackburn | cool | 23:12 |
| blackburn | KMcQuisten: cool too :) | 23:12 |
| KMcQuisten | Looks like we got this squared away for now. | 23:12 |
| KMcQuisten | Thanks for all your helop | 23:12 |
| blackburn | no problem! ok then I know something is broken in linadd here | 23:12 |
| KMcQuisten | Glad I could help root these out. | 23:13 |
| KMcQuisten | I think I may have found another one, though. | 23:14 |
| KMcQuisten | if I do mkl.get_kernel().get_subkernel_weights() to extract the weights after training, I get this: | 23:14 |
| KMcQuisten | Traceback (most recent call last): File "mkl_linadd_regression.py", line 76, in <module> mkl_binclass_modular (*parameter_list[0]) File "mkl_linadd_regression.py", line 71, in mkl_binclass_modular print mkl.get_kernel().get_subkernel_weights() | 23:16 |
| KMcQuisten | TypeError: Kernel_get_subkernel_weights expected 1 arguments, got 0 | 23:16 |
| blackburn | hmm | 23:17 |
| KMcQuisten | If I just use the method on a frech CombinedKernel, everything works fine, but if I pass a kernel to a machine and train it, I get that error when I try to extract the weights | 23:17 |
| blackburn | ahh I think I know | 23:17 |
| KMcQuisten | righto | 23:18 |
| blackburn | different types | 23:18 |
| KMcQuisten | Yes. when I extract the kernel, it's just type "Kernel", | 23:18 |
| blackburn | get_kernel() returns CKernel | 23:18 |
| blackburn | so rather use old pointer or cast it somehow | 23:18 |
| KMcQuisten | Then how should I get my subkernel weights after I train an MKL? | 23:18 |
| blackburn | let me check why CKernel has that method | 23:18 |
| blackburn | well you have combined kernel somewhere in code | 23:19 |
| blackburn | just call get_subkernel_weights on that | 23:19 |
| blackburn | it will be the same kernel still after train too | 23:19 |
| KMcQuisten | if I call the method from the variable I used to set up the combined kernel, it segfaults | 23:19 |
| blackburn | oh | 23:19 |
| blackburn | cool | 23:19 |
| blackburn | let me fix it then | 23:19 |
