| kislay | pickle27, yo! | 03:31 |
| pickle27 | kislay: whats up? | 03:32 |
| kislay | pickle27, http://pastebin.com/Uz2CJi3X | 03:32 |
| kislay | pickle27, A small eg. of DenseSGMatrixFactory. | 03:32 |
| pickle27 | kislay: looks good | 03:33 |
| pickle27 | can you have a default on the dense factory too plz | 03:34 |
| kislay | yes sure | 03:34 |
| kislay | But we need CDenseFeatures<float64_t> a lot. | 03:34 |
| kislay | pickle27, So, I think we must convert all of them to <float64_t> | 03:35 |
| pickle27 | kislay: actually this is a good point | 03:36 |
| pickle27 | this is something we need to think about | 03:36 |
| pickle27 | do we want to incorporate switching the type with the conversions | 03:37 |
| pickle27 | or do we always do 1 to 1 types and then you can change the shogun type after if you need | 03:37 |
| kislay | I think we should maintain the way the Matrix was originally presented to us. | 03:38 |
| pickle27 | okay lets go with that then | 03:38 |
| pickle27 | you'll need to extend the current implementation to include getting the type from the input and choosing the appropriate type for the output | 03:38 |
| kislay | But again, I don't know how to do it. Templates right? | 03:39 |
| pickle27 | I don't think you'll need templates | 03:39 |
| pickle27 | you can ask a cvMat what its type is | 03:39 |
| pickle27 | and then lookup what the corresponding shogun type is from a constant | 03:39 |
| pickle27 | then pass that result into the SGMatrix constructor that you are going to return | 03:40 |
| pickle27 | make sense? | 03:40 |
| kislay | yeah. | 03:40 |
| kislay | very appropriate it seems to me. Btw the other method you suggested is good too. | 03:41 |
| kislay | what's your views? | 03:41 |
| pickle27 | I like simple so I agree we should return a matrix of the same type as was given to us | 03:41 |
| pickle27 | is that what you meant> | 03:42 |
| kislay | that is right. The other method where we do 1 to 1 types..i.e always generate uint8_t but at the last moment convert it into the required type. | 03:43 |
| pickle27 | lets just go 1 to 1 | 03:44 |
| kislay | err.. the one which you explained to me. that one, right? | 03:44 |
| pickle27 | yeah! | 03:45 |
| kislay | yup. | 03:45 |
| pickle27 | getting the type of the input and then setting the output type to match | 03:45 |
| pickle27 | you'll need a constant that maps cv types to shogun types | 03:46 |
| kislay | yeah. It looks elegant. | 03:46 |
| pickle27 | check out std::map | 03:46 |
| pickle27 | should do the trick | 03:46 |
| kislay | great! thanks | 03:46 |

| kislay | hey lisitsyn | 17:43 |
| lisitsyn | kislay: hey | 17:43 |
| @besser82 | lisitsyn, ho! | 17:44 |
| lisitsyn | besser82: hey | 17:44 |
| @besser82 | lisitsyn, how is it? | 17:44 |
| @besser82 | lisitsyn, any news on the data?!? | 17:44 |
| lisitsyn | besser82: sorry it was very intense | 17:44 |
| @besser82 | lisitsyn, np ;) | 17:44 |
| kislay | I need some help in Cpp. could you look this http://pastebin.com/qj3BqLTs. | 17:44 |
| lisitsyn | I was ill and now trying to catch up with my thesis | 17:44 |
| @besser82 | lisitsyn, allrighty! ;) | 17:44 |
| lisitsyn | have like a few more days to get it polished | 17:44 |
| @besser82 | lisitsyn, like me with results on the data :-P | 17:45 |
| lisitsyn | besser82: it would be next thing ;) | 17:45 |
| @besser82 | lisitsyn, don't hurry | 17:45 |
| lisitsyn | kislay: alright - what is it? | 17:45 |
| @besser82 | lisitsyn, the clustering stuff is nearly ready2go ;) | 17:45 |
| lisitsyn | besser82: cool | 17:45 |
| @besser82 | lisitsyn, next would be deep sentiment stuff =) | 17:46 |
| kislay | lisitsyn, converting opencv matrix into SGMatrix. | 17:46 |
| lisitsyn | kislay: yeah that's pretty clear ;) I mean the question | 17:46 |
| kislay | lisitsyn, I am not getting how to get those mapped values into arguments of SGMatrix< > templates!! | 17:47 |
| kislay | lisitsyn, the String I have shown there is obviously wrong. Just to print the output I did tha | 17:48 |
| kislay | lisitsyn, what should be the map<int, *type*> | 17:49 |
| lisitsyn | what is this map intended for? | 17:49 |
| kislay | to invoke the correct SGMatrix constructor... i.e according to the type of the opencv matrix. | 17:49 |
| lisitsyn | I guess you need templated getMatrix function | 17:50 |
| lisitsyn | like template <typename T> SGMatrix<T> getMatrix(Mat); | 17:50 |
| lisitsyn | I see no other way as Mat has erased its type | 17:50 |
| kislay | ah! | 17:50 |
| kislay | lisitsyn, okay. I will hack a bit. thanks. | 17:52 |
| lisitsyn | kislay: it would be possible if we could make SGMatrix like 'polymorphic' | 17:58 |
| lisitsyn | but it is somewhat called value type | 17:58 |
| lisitsyn | you just have its value and its efficient type is the same | 17:58 |
| lisitsyn | so actually SGMatrix<int> and SGMatrix<float> are totally different classes with nothing in common | 17:58 |
| kislay | lisitsyn, so you suggest this as viable too, right? | 18:00 |
| lisitsyn | kislay: you'd have to put a type in any case | 18:00 |
| lisitsyn | so it would be | 18:00 |
| lisitsyn | getMatrix<float>(Mat) | 18:00 |
| lisitsyn | or whatever type it is | 18:00 |
| lisitsyn | I don't think it is possible to obtain the type of Mat's element | 18:01 |
| lisitsyn | you can only try to convert it and check whether this conversion is ok | 18:01 |
| kislay | lisitsyn, ok | 18:02 |

| yorkerlin | Hi Can anyone tell whether my guess about this construct SGVector(T * v,index_t len,bool ref_counting = true) is correct or not? My guess is the SGVector will RE-USE the memory space in v and will AUTOMATICALLY clean-up (DELETE) the memory space if we use SGVector instance instead of SGVector pointer. | 23:38 |
| thoralf|home | yorkerlin: You should check the implementation. | 23:39 |
| thoralf|home | yorkerlin: Tell me what you think (after reading the code) and I'll tell you if it was true. | 23:39 |
| thoralf|home | :) | 23:39 |
| yorkerlin | ic | 23:39 |
| yorkerlin | I check the implementation. It seems my guess is correct. | 23:47 |
| thoralf|home | yorkerlin: Seems it's just copying the provided pointer... and it gets freed. | 23:50 |
| thoralf|home | yorkerlin: You know that you don't need to do "new SGVector(v, len, true)" but just "new SGVector(v, len)"? | 23:51 |
| thoralf|home | ref_count=true is passed as default parameter | 23:51 |
| yorkerlin | Yes | 23:52 |
| yorkerlin | Thanks for your quick reply | 23:52 |
