| @iglesiasg | deerishi: is kernel pca a preprocessor? I thought it was a converter | 10:22 |
| @lisitsyn | iglesiasg: preprocessor still | 10:22 |
| @iglesiasg | aham I see | 10:23 |
| @iglesiasg | lisitsyn: isn't included in tapkee then? | 10:23 |
| -!- sonne|work [~sonnenbu@sams-office-nat.tomtomgroup.com] has quit [Quit: Leaving.] | 10:23 | |
| deerishi | i did preprocessor=KernelPCA(kernel) ,now m trying to plot the data | 10:23 |
| @lisitsyn | iglesiasg: it is -but currently it uses old code | 10:23 |
| -!- sonne|work [~sonnenbu@sams-office-nat.tomtomgroup.com] has joined #shogun | 10:23 | |
| @iglesiasg | lisitsyn: understood | 10:24 |
| deerishi | e.g. the input data is 2x302 , but m getting a data of 1x302 after kernelpca | 10:24 |
| @iglesiasg | deerishi: maybe you should transpose the data? no real idea, just wild guess | 10:25 |
| deerishi | willl just try that | 10:25 |
| @iglesiasg | deerishi: or wait, it sort of makes sense | 10:25 |
| @iglesiasg | deerishi: you have 302 points in 2D right? two points in R^302 sounds weird - too few points | 10:26 |
| deerishi | i have 2 not separable datasets ,i.e total of 302 points in 2d | 10:27 |
| deerishi | the data is 2 semicircular arcs | 10:29 |
| deerishi | in the same quadrants | 10:29 |
| @iglesiasg | deerishi: why are you talking about separable datasets? | 10:30 |
| -!- sonne|work [~sonnenbu@sams-office-nat.tomtomgroup.com] has quit [Remote host closed the connection] | 10:30 | |
| @lisitsyn | kpca has nothing to do with separability | 10:30 |
| -!- sonne|work [~sonnenbu@sams-office-nat.tomtomgroup.com] has joined #shogun | 10:32 | |
| deerishi | but one should be able to distinguish 2 sets os data,after kernel pca,rite? | 10:32 |
| @lisitsyn | ah yes | 10:32 |
| @iglesiasg | deerishi: one should be, but the method is not going to tell you about that | 10:32 |
| deerishi | k.I am trying to solve the bug about kernelpca test/check . | 10:33 |
| deerishi | i should be able to see after plotting that kernel pca works, | 10:34 |
| deerishi | the dimension of the data i am getting is just a single row,how can i plot that and see if the algorithim has worked or not? | 10:35 |
| @lisitsyn | well plot points on a line | 10:36 |
| @iglesiasg | if your intuition is correct, then you should see two parts of the line populated with points | 10:37 |

| sonne|work | HeikoS: any comments about the workshop announcement mail? | 11:10 |
| sonne|work | If not I will send it out this evening. | 11:10 |
| HeikoS | sonne|work: ah sorry, haven't looked yet, will do now | 11:10 |
| @lisitsyn | HeikoS: I am afraid you speak about PCA | 11:11 |
| @lisitsyn | not kPCA | 11:11 |
| @lisitsyn | HeikoS: there is no such thing like projection matrix in kpca | 11:12 |
| HeikoS | lisitsyn: what does the projection matrix give you then? | 11:12 |
| HeikoS | or transformation matrix | 11:13 |
| HeikoS | this is a matrix that the data is projected on | 11:13 |
| HeikoS | at least this is what the apply method does | 11:13 |
| HeikoS | not correct? | 11:13 |
| @lisitsyn | HeikoS: yes, already projected data | 11:13 |
| HeikoS | lisitsyn: so the get_transformation matrix method returns the projected data? | 11:14 |
| HeikoS | what does apply_to_features do? | 11:14 |
| HeikoS | if I look at the code this looks like a projection | 11:14 |
| @lisitsyn | let me check | 11:14 |
| @lisitsyn | HeikoS: ehmm | 11:15 |

| HeikoS | lisitsyn: haha :) | 11:16 |
| HeikoS | good that we started investigating :) | 11:16 |
| @lisitsyn | HeikoS: well may be I misunderstand something | 11:16 |
| @lisitsyn | but kpca is not a linear method | 11:17 |
| @lisitsyn | in my head | 11:17 |
| HeikoS | it is in the feature space right? | 11:17 |
| @lisitsyn | HeikoS: top eigenvectors of centered kernel matrix | 11:17 |
| HeikoS | yes | 11:17 |
| @lisitsyn | that is the projection | 11:17 |
| @lisitsyn | not a projection matrix to be multiplied | 11:17 |
| HeikoS | so the projection is | 11:20 |
| @lisitsyn | HeikoS: ah it seems everything is ok here | 11:21 |
| HeikoS | lisitsyn: so whats the difference between apply and get_transform? | 11:22 |
| @lisitsyn | but my understanding of kpca was not complete | 11:22 |

| @iglesiasg | hey randomname | 14:42 |
| randomname | Is there any class similar to SGVector for priority_queue or heap ? | 14:42 |
| randomname | I mean something similar to SGHeap | 14:42 |
| @iglesiasg | randomname: IIRC there is some fibonacci head somewhere | 14:42 |
| @iglesiasg | fibonacci heap, not head hehe | 14:43 |
| @lisitsyn | I removed that as it was not needed | 14:43 |
| @lisitsyn | randomname: what for? | 14:43 |
| @iglesiasg | randomname: anyway, if you just need to use it in your cpp (not in header) feel free to use STL | 14:43 |
| randomname | we can use STL ? | 14:44 |
| randomname | thats great :) | 14:44 |

| @iglesiasg | randomname: but only in implementation files please, not headers | 14:44 |
| deerishi | have posted the kernelpca test.check | 14:44 |
| randomname | lisitsyn: I need for a patch on Ball Tree for KNN | 14:44 |
| deerishi | can anyone see the result and get back to me | 14:44 |
| deerishi | i have also posted the plots of the results | 14:45 |
| @iglesiasg | deerishi: the second plot is the density of the points after kpca I guess | 14:45 |
| @iglesiasg | deerishi: or? | 14:45 |
| deerishi | yes | 14:45 |
| @iglesiasg | so no actual coordinates right? | 14:45 |
| @iglesiasg | I think it looks fine | 14:46 |
| @iglesiasg | I wonder why one of them is in 50 and the other in 200 though, since the original are of radii 50 and 100 | 14:46 |
| @iglesiasg | but I guess it is fine | 14:46 |
| deerishi | i just took the vector returned after apply_to _feature_matrices and plotted it | 14:46 |
| @lisitsyn | randomname: yes, use stl priority heap in .cpp | 14:46 |
| randomname | I have another question: I should be making another class BallTreeNodeData.h or just a simple struct def in the code will do ? | 14:47 |
| randomname | lisitsyn: thanks :) | 14:47 |
| deerishi | @iglesiasg ,so did i do as per required in the task? | 14:47 |
| deerishi | ? | 14:47 |
| @lisitsyn | randomname: that's ok to have struct here I believe | 14:48 |
| randomname | lisitsyn: thanks :) that helped ... I was on my way to make separate class files for Ball Tree Node :) | 14:49 |
| @iglesiasg | deerishi: do you think the second plot with the results makes sense? | 14:49 |
| randomname | but now I can do it with just a struct :) | 14:49 |

| deerishi | any suggestions on how to improve | 14:53 |
| @iglesiasg | deerishi: you can draw inspiration from http://scikit-learn.org/dev/auto_examples/decomposition/plot_kernel_pca.html | 14:53 |
| @lisitsyn | it actually makes sense to make an homomorphous mapping here 2d->2d | 14:54 |
| @lisitsyn | as it is implicitly \inf d -> 2d | 14:54 |
| @lisitsyn | in case of gaussian kernel | 14:55 |
| @iglesiasg | what is homomorphous in this context? | 14:55 |
| @iglesiasg | simply that it doesn't reduce dim? | 14:55 |
| @lisitsyn | iglesiasg: X -> X | 14:55 |
| @iglesiasg | ok | 14:55 |
| @lisitsyn | doesn't change the space | 14:55 |
| @lisitsyn | iglesiasg: as we are actually mapping rkhs of X -> X | 14:56 |
| @lisitsyn | I think that's ok | 14:56 |
| @iglesiasg | rkhs? | 14:56 |

| @iglesiasg | :) | 15:03 |

| HeikoS | does it fail on the buildbot? | 16:55 |
| HeikoS | no idea | 16:55 |
| wiking | mmm lemme check | 16:55 |

| HeikoS | weird | 16:59 |
| wiking | in /SubGradientSVM_30_1en05_16_05_False.m | 16:59 |
| HeikoS | maybe some library not available? | 16:59 |
| wiking | everything else works fine | 16:59 |
| wiking | only this one fails | 16:59 |
| wiking | e.g. SubGradientSVM_30_1en05_1_05_False.m | 17:00 |
| wiking | aaaah | 17:00 |
| wiking | why might SubGradientSVM_30_1en05_1_05_False.m be skipped? | 17:00 |
| wiking | because of some library missing? | 17:00 |
| HeikoS | no I mean sometimes we have fallback code | 17:00 |
| HeikoS | when a library is not available | 17:01 |
| HeikoS | which might be less accurate | 17:01 |
| wiking | according to diff -uN ./data/testsuite/classifier/SubGradientSVM_30_1en05_16_05_False.m ./data/testsuite/classifier/SubGradientSVM_30_1en05_1_05_False.m | 17:02 |
| wiking | the only difference is the number of threads | 17:02 |
| HeikoS | mmh | 17:02 |
| HeikoS | that doesnt sound good ;) | 17:02 |
| wiking | anyhow it skips SubGradientSVM_30_1en05_1_05_False.m and SubGradientSVM_30_1en05_16_05_False.m fails with that error | 17:05 |
| wiking | if anybody has any idea what's going on please let me know, i.e. knows what package might be missing etc : | 17:06 |
| wiking | :) | 17:06 |
| HeikoS | wiking: sonney2k might know | 17:08 |
| gsomix | HeikoS, hey, have a minute? just little question. as you know lisitsyn came up new syntax for modelselection. | 17:15 |
| gsomix | like ModelSelectionParameter("kernel").as(ValuesSet).from([gaussian_kernel, linear_kernel, chi2_kernel]); | 17:15 |
| HeikoS | gsomix: sure | 17:15 |
| HeikoS | I think its documented in the issue | 17:15 |
| gsomix | how do you think is it good to store ModelselectionParameter in SGObjects? | 17:16 |
| gsomix | for syntax like yet_another_machine.paramete('kernel').as(...)... | 17:16 |
| HeikoS | gsomix: I dont understand | 17:17 |
| HeikoS | the model selection parameters are already stored in the SGObject | 17:17 |
| HeikoS | but we need to construct the parameter tree from this syntax | 17:18 |
| HeikoS | curently, those trees are created by hand | 17:18 |
| HeikoS | see python modelselection examples | 17:18 |
| HeikoS | this should be easier | 17:18 |
| gsomix | HeikoS, err. I mean to store parameters tree in SGObject. | 17:19 |
| gsomix | for automagically constructing without new local variables in code | 17:19 |
| HeikoS | I see | 17:20 |
| HeikoS | so I would just make this syntax return a parameter tree | 17:20 |
| HeikoS | and those can then be appended to each other | 17:20 |
| HeikoS | and the modelselection class takes parameter trees as inputs | 17:20 |

| Asix3 | Greetings! I'm interested in working for Shogun through GSOC. I have a little background in both machine learning and C++, but not much else -- including git and working on large scale projects. I'm looking at Large Scale Learning & Dimension reduction using hashing. | 22:44 |
| @lisitsyn | Asix3: hey | 22:44 |
| Asix3 | @lisitsyn: Hi! I didn't expect a response so quickly. I'm basically wondering if I'd be a good candidate given my background. I've nearly worked through stanfords free machine learning course, now available on coursera -- found it challenging, but also interesting and completely doable. Aside from that I've taken a few courses in C++, two were introductory and one was on algorithms and data structures | 22:47 |
| @lisitsyn | Asix3: I'd suggest start learning the project structure and try to improve anything (you may find some issues at github) | 22:47 |
| Asix3 | @lisitsyn: Will do! Thank you! | 22:47 |
| @lisitsyn | Asix3: we are searching for motivated and interested students :) | 22:48 |
| @lisitsyn | so background matters but not that much | 22:48 |
| Asix3 | I'm definitely both... Thanks again. You will be seeing more of me on this channel as I try to set up shogun and submit work on one of your entry tasks | 22:49 |
| @lisitsyn | Asix3: would be nice! | 22:50 |
