| K0stIa1 | HI, all! I'm using shogun in python. My shogun.Distribution doesn't have Gaussian, GMM... can anyone give my advice why is it so ? | 16:52 |

| n4nd0 | blackburn: hey! how are you doing? | 20:10 |
| blackburn | n4nd0: hey pretty fine | 20:13 |
| blackburn | what about you? | 20:13 |
| n4nd0 | blackburn: I am fine too | 20:13 |
| n4nd0 | blackburn: I start to feel happy with the hmsvm :) | 20:13 |
| blackburn | heh | 20:13 |
| blackburn | did you test it already? | 20:14 |
| n4nd0 | I am getting the same results for small examples | 20:14 |
| n4nd0 | up to 10 training examples right now | 20:14 |
| n4nd0 | and after lot of errors fixed, the results are the same | 20:14 |
| n4nd0 | blackburn: I want to try now with larger datasets | 20:14 |
| n4nd0 | it could be really good if I could use the .mat files that can be generated with the hmsvm toolbox | 20:15 |
| blackburn | n4nd0: btw I have bad understanding what can be HM outputted? | 20:15 |
| blackburn | n4nd0: what are you using for tests? | 20:15 |
| n4nd0 | blackburn: what do you mean with HM outputted? | 20:15 |
| n4nd0 | blackburn: just manually generated toy data | 20:16 |
| blackburn | for example if I have images | 20:16 |
| blackburn | what can be HMs? | 20:16 |
| n4nd0 | mmm do you mean what problem can be modelled with an hmm? | 20:16 |
| blackburn | in case of bioinf stuff it goes to 4 state model like ACTG | 20:16 |
| n4nd0 | problems* | 20:16 |
| blackburn | yeah | 20:16 |
| blackburn | but what are other examples? | 20:16 |
| n4nd0 | I haven't used HMMs in computer vision | 20:17 |
| n4nd0 | so I cannot tell you about what it could be in an image | 20:17 |
| n4nd0 | I have googled it right now | 20:18 |
| n4nd0 | it seems that it is used in gesture recognition | 20:18 |
| n4nd0 | my guess: | 20:18 |
| n4nd0 | the hidden states are the gestures themselves | 20:18 |
| n4nd0 | the observation may be features extracted from images | 20:19 |
| blackburn | hmm that sounds interesting :) | 20:19 |
| n4nd0 | blackburn: anyway, do you know if I can load from python *any* .mat file? | 20:19 |
| blackburn | n4nd0: sure you can | 20:19 |
| blackburn | scipy.io.loadmat | 20:19 |
| n4nd0 | when I tried to load the ones generated by the hmsvm toolbox | 20:20 |
| n4nd0 | I got some errors, but I was probably doing somethiing wrong | 20:20 |
| blackburn | errors like? | 20:20 |
| n4nd0 | mmm let me check | 20:20 |
| n4nd0 | it was a couple of weeks ago when I tried this | 20:20 |
| n4nd0 | I don't even have that code more | 20:21 |
| n4nd0 | it was something very simple, 5-10 lines loading a module and trying to load the .mat file | 20:21 |
| n4nd0 | importing a module, better | 20:21 |
| blackburn | I use .mat loading in my tester scripts and it works nice | 20:22 |
| n4nd0 | is any of those in the repo? | 20:22 |
| n4nd0 | using this from tools.load import LoadMatrix it didn't work out well | 20:22 |
| blackburn | n4nd0: use scipy.io.loadmat | 20:25 |
| blackburn | n4nd0: it returns dictionary matlab_name -> value | 20:28 |
| n4nd0 | blackburn: nice! | 20:29 |
| n4nd0 | I could get it to work | 20:29 |
| n4nd0 | thank you very much :) | 20:29 |
| n4nd0 | ok, I am going to take a break now to have dinner and see the games | 20:30 |
| n4nd0 | see you later! | 20:30 |
| blackburn | n4nd0: :) see you | 20:30 |
