| siddharth_ | hi sonney2k | 07:26 |
|---|---|---|
| @bettyboo | ho | 07:26 |
| @sonney2k | siddharth_, morning. | 07:27 |
| siddharth_ | well I asked the author of that Matlab toolbox | 07:27 |
| siddharth_ | and he said that its fine as long as you use this for open software | 07:27 |
| siddharth_ | sonney2k, so should I go for two proposals ... One for the Newton Primal SVM solver and other one for Dim Reduction? | 07:30 |
| * siddharth_ wondering how busy sonney2k must be :P | 07:35 | |

| Tanmoy | @sonney2k do we have to add some more classes to the preprocessing base class | 09:15 |
| Tanmoy | @sonney2k well not actually maybe to CPreProc but maybe to CSimplePreProc | 09:17 |
| @sonney2k | siddharth_, sorry was haiving breakfast... you had the idea about all these different dim reduction methods that you found in some matlab toolbox right? | 09:25 |
| @sonney2k | Tanmoy, totally up to you | 09:26 |
| @sonney2k | if you think you can define some preprocs that share a good subset of features (e.g. all use a kernel in some way and have the same kind of apply() function) then it makes totally sense | 09:27 |
| @sonney2k | siddharth_, just see your email. yes, makes perfectly sense. I tend to even say that the dim reduction techniques open up a new field inside shogun - so I would even consider this proposal to be stronger | 09:29 |
| -!- aifargonos [~aifargono@46.18.27.35] has joined #shogun | 09:30 | |
| Tanmoy | @sonney2k well the reason after scanning thru wat i felt is because the sparsity DS which u have defined is strong | 09:35 |
| Tanmoy | but got Sparse Regression i don't know how strong it could be | 09:35 |
| Tanmoy | so i have defined some of my own proc | 09:35 |
| Tanmoy | wld discuss with chris too and add it to the proposal | 09:36 |
| @sonney2k | Tanmoy, well one could of course write two preprocs one for sparse and one for dense features... not sure how much functionality they can exchange... | 09:36 |
| Tanmoy | @sonney2k at this stage dense would not really be a probs i think what you have is good enough | 09:39 |
| Tanmoy | i have talked to chris of doing some work after GSOC so shld be good enough | 09:39 |
| Tanmoy | to do it then | 09:40 |
| Tanmoy | ill also be in saarnucken so hope to ctch u guys thr | 09:40 |
| Tanmoy | btw im kinda dissapoointed tht the mentors for strcutrued learning are kinda absent | 09:40 |
| Tanmoy | is tht project going on or stopped ? | 09:41 |
| @sonney2k | Tanmoy, hmmhh both of them? | 09:42 |
| @sonney2k | I now that Nico is or has just returned form a conference in Vancouver | 09:42 |
| Tanmoy | well Jonas did reply | 09:42 |
| Tanmoy | nico not yet | 09:42 |
| Tanmoy | thrs even hardly any time to discuss | 09:42 |
| @sonney2k | well that explains it then? | 09:43 |
| Tanmoy | yeah but was a good proposal | 09:43 |
| Tanmoy | i mean u have kernel learning in shogun | 09:43 |
| @sonney2k | hmhhh, I will see Nico today in person so ask him now | 09:43 |
| Tanmoy | but structured learning in kernels and CRF's wld be very neat | 09:43 |
| @sonney2k | so he will then respond later in the day... | 09:44 |
| Tanmoy | :) gr8 sounds fair | 09:44 |
| Tanmoy | btw anything in SHOGUN right now for MAP estimation | 09:46 |
| Tanmoy | i mean any class defined for Prob distributions | 09:46 |
| siddharth_ | sonney2k, Well I will give 2 proposals and whichever you select will be fine by me :) | 09:47 |

| Ziyuan | "lib/common.h" includes a header file "lib/config.h" while there's no such a file. | 11:29 |
| aifargonos | it is generated automatically ... build first | 11:34 |
| aifargonos | or maybe I am wrong ?? | 11:36 |
| aifargonos | no ... class_list in base is generated automatically ... sorry for confusion .. | 11:37 |
| -!- hiteshk [~hitesh_na@117.211.88.150] has joined #shogun | 11:40 | |
| Ziyuan | wait... | 11:47 |
| @sonney2k | yes class_list.cpp is generated using class_list*template* and the script that does it is the class_list.cpp.py | 11:54 |
| @sonney2k | this is necessary for us to get a mapping class name -> class | 11:54 |
| @sonney2k | (for serialization) | 11:54 |
| aifargonos | btw, sonney2k: all this source files with *Serializable* in their name are used for serialization ... But what are other sources with *File* in their name used for ?? | 11:58 |
| aifargonos | like AsciiFile, HDF5File or even SimpleFile ?? | 11:58 |
| @sonney2k | aifargonos, just plain matrix / vector / string i/o, e.g. read a list of strings (for shogun's string features) or a matrix (for shoguns simplefeatures) | 11:58 |
| aifargonos | yeah .: I understood the code, but where are they used ?? Are they used inside shogun, or are they just for users ?? | 11:59 |
| @sonney2k | aifargonos, inside of shogun of course | 12:00 |
| @sonney2k | but shogun methods only use the interface class CFIle | 12:01 |
| aifargonos | Where in shogun can I find examples of their usage ?? | 12:03 |
| @sonney2k | e.g. in CSimpleFeatures, CStringFeatures, CSparseFeatures | 12:05 |

| @sonney2k | Ziyuan, I think the serial one is enough | 14:42 |
| @sonney2k | Ziyuan, snappy is just for some fast compression... | 14:42 |
| Tanmoy | @sonney2k gr8 and thnks | 14:45 |
| Tanmoy | also u think for GP a binary and multi class demo with Toy data is reasonable | 14:45 |
| Tanmoy | or data should be from bio informatics domain | 14:45 |

| Ziyuan | Toy code fails to run: I've run a build for libshogun (configure -> make -> make install) which generated libshogun.so and libshogun.a. And then I set up another tentative project in Eclipse, adding the include paths ("/.../src/libshogun") and libraries paths ("/.../src/libshogun/libshogun.so" and ".../libshogun.a"). But Eclipse complains that it cannot find the two libraries. So what steps do | 20:36 |
| Ziyuan | I need to have the code run normally? | 20:36 |
| Ziyuan | It must be easy... | 20:36 |
