| @knrrrd | ;) | 10:56 |
| @bettyboo | hihi | 10:56 |
| @sonney2k | bettyboo, are you always smiling? | 10:58 |
| @bettyboo | sonney2k: but you are interested in shogun? | 10:58 |
| @sonney2k | bettyboo, yes of course - now I understand the reason why you are smiling. | 10:59 |
| @bettyboo | sonney2k: input set of strings, output n-dimensional representation | 10:59 |
| @sonney2k | bettyboo, You are talkng about kPCA or KFA right? | 10:59 |
| @bettyboo | sonney2k: shogun: Implement snappy compression support (http://code.google.com/p/snappy/). | 10:59 |
| Tanmoy | @sonney2k some of the preprocessing methods for example norm won't it be better to use GSL's code | 11:24 |
| Tanmoy | especially BLAS | 11:24 |

| @sonney2k | Tanmoy, I am not sure I understand: Did you mean we should use blas whenever possible? | 12:30 |
| @sonney2k | because - that is what we are trying | 12:35 |
| @sonney2k | (though the preproc code is probably among the oldest parts of shogun and not yet utilizing all of that) | 12:36 |
| Tanmoy | @sonney2k yes thts wat i mean | 12:42 |
| Tanmoy | for example why would this be required http://www.shogun-toolbox.org/doc/classshogun_1_1CNormOne.html | 12:43 |
| Tanmoy | http://www.gnu.org/softhttp://www.gnu.org/software/gsl/manual/html_node/Level-1-GSL-BLAS-Interface.html | 12:43 |
| Tanmoy | when already implemented as a norm in BLAS | 12:43 |
| Tanmoy | @sonney2k however for the missing algorithms part i think the desgn issues needs to be a bit better sorted out | 12:44 |
| @sonney2k | Tanmoy, well one is a preprocessor that you can attach to features and one is just the method to compute the norm of a vector | 12:44 |
| Tanmoy | but i belive the work is to find norm right ? | 12:45 |
| @sonney2k | no, it is that when you have a set of vectors to ensure that they all have norm one. | 12:46 |
| @sonney2k | so divide each vector by its norm | 12:46 |
| @sonney2k | it is actually using blas already... | 12:47 |
| Tanmoy | yup | 12:47 |
| Tanmoy | the link i sent was for norm | 12:47 |
| Tanmoy | maybe i shld have said divide by norm :) | 12:48 |

| mank | @sonney2k, Hi. I had sent you an email regarding GSoC Project ( i/o in .hdf5 format ) | 13:00 |
| @sonney2k | mank, I recall answering :) | 13:00 |
| mank | yeah, I wanted to discuss more about it. | 13:01 |
| @knrrrd | woah, truecrypt really improved in terms of GUI and usability | 13:01 |
| @knrrrd | generating a encrypted harddisk is really easy now | 13:01 |
| @knrrrd | and its cross-platform (in contrast to linux and osx specific drivers) | 13:02 |
| mank | @sonney2k, Is it a good time to discuss ? | 13:08 |
| @sonney2k | mank, if it does not take too long - ask! | 13:09 |
| mank | Ok, couple of quick questions. | 13:09 |
| mank | 1. Are we going to use HDF5 Api's for i/o ? | 13:10 |
| blackburn | sonney2k: I have implemented a fast nearest neighbor classification (in case of k=1) in CKNN class. what should I do after cleaning and commenting to get it commited? | 13:10 |
| mank | 2. where should i start from ? | 13:11 |
| -!- siddharth__ [~siddharth@117.211.88.150] has joined #shogun | 13:11 | |
| @sonney2k | mank, hdf5 api's are already used for i/o look at CHDF5File and the CSerializableHDF5File classes | 13:12 |
| @sonney2k | mank, look at the CFile API | 13:13 |
| @sonney2k | blackburn, submit a patch to the mailing list (attach what git format-patch produces ) | 13:14 |
| blackburn | sonney2k: okay, thank you | 13:14 |
| mank | @sonney2k: Thank you. I am really interested in working on this. I will have a look at this and maybe discuss more after going through these resources. | 13:16 |
| @sonney2k | mank, it would really make sense to do the octave / and older matlab binary formats too... for that look also at the source of octave (it's linked to at the gsoc page) | 13:17 |
| mank | ok. I will have a look at that too. | 13:17 |
| mank | @sonney2k, Thanks for your time! | 13:18 |

| siddharth__ | sonney2k, hi | 16:16 |
| @bettyboo | siddharth__, hey | 16:16 |
| siddharth__ | hey | 16:16 |
| @bettyboo | ho | 16:16 |
| siddharth__ | Dimensionality reduction methods like LLE,ISOMAP not implemented in Shogun right? | 16:17 |
| blackburn | I will send a proposal about it | 16:17 |
| siddharth__ | you working on this? | 16:17 |
| blackburn | not working, want to | 16:18 |
| siddharth__ | so can two people do and divide the work? | 16:18 |
| blackburn | I don't know, even don't know any chances to get into this program :) | 16:19 |
| @bettyboo | funny ;> | 16:19 |
| siddharth__ | :P | 16:19 |
| @bettyboo | lol ;D | 16:19 |
| blackburn | btw, there is a kernel pca not implemented | 16:20 |
| siddharth__ | actually there are many Dimensionality Reduction methods yet to be implemented | 16:20 |
| blackburn | or implemented.. I forgot | 16:20 |
| blackburn | I'll try to send a proposal about LLE, SNE, ISOMAP and MDS | 16:20 |
| siddharth__ | well lets see...I am also interested in this | 16:22 |
| siddharth__ | what about boosting algorithms? | 16:22 |
| blackburn | what is the question? :) | 16:23 |
| @bettyboo | :> | 16:23 |
| siddharth__ | I mean they are also not implemented right? | 16:23 |
| blackburn | I don't pretty sure, but there is an classifier/boosting | 16:24 |
| siddharth__ | yeah that i went through | 16:25 |
| siddharth__ | most of them implemented | 16:25 |
| blackburn | I thought you already chose idea to work with | 16:27 |
| siddharth__ | yeah I am interested in implementing primal SVM solver...though if this finishes quickly,I want to do work on Dim Red | 16:29 |
| blackburn | ah, I see | 16:30 |
| @knrrrd | there is also the kfa task. | 16:30 |
| @knrrrd | if you are interested. | 16:30 |
| siddharth__ | ok I will look into that | 16:31 |
| @knrrrd | lle, sne and isomap would also be interesting, as they all require a knn backend | 16:32 |
| -!- serialhex is now known as gsoc_serialhex | 16:32 | |
| @knrrrd | where mds can be build ontop of pca easily | 16:32 |
| blackburn | isomap is very similar to mds too | 16:33 |
| @knrrrd | blackburn: yes? how that? | 16:34 |
| @knrrrd | ah. yes, isomap employs mds is the last step | 16:35 |
| @knrrrd | i recall | 16:35 |
| blackburn | knrrrd: it is like mds, but with graph distance | 16:35 |
| blackburn | yeap | 16:35 |
