n4nd0blackburn: hey! how are you doing?20:10
blackburnn4nd0: hey pretty fine20:13
blackburnwhat about you?20:13
n4nd0blackburn: I am fine too20:13
n4nd0blackburn: I start to feel happy with the hmsvm :)20:13
blackburnheh20:13
blackburndid you test it already?20:14
n4nd0I am getting the same results for small examples20:14
n4nd0up to 10 training examples right now20:14
n4nd0and after lot of errors fixed, the results are the same20:14
n4nd0blackburn: I want to try now with larger datasets20:14
n4nd0it could be really good if I could use the .mat files that can be generated with the hmsvm toolbox20:15
blackburnn4nd0: btw I have bad understanding what can be HM outputted?20:15
blackburnn4nd0: what are you using for tests?20:15
n4nd0blackburn: what do you mean with HM outputted?20:15
n4nd0blackburn: just manually generated toy data20:16
blackburnfor example if I have images20:16
blackburnwhat can be HMs?20:16
n4nd0mmm do you mean what problem can be modelled with an hmm?20:16
blackburnin case of bioinf stuff it goes to 4 state model like ACTG20:16
n4nd0problems*20:16
blackburnyeah20:16
blackburnbut what are other examples?20:16
n4nd0I haven't used HMMs in computer vision20:17
n4nd0so I cannot tell you about what it could be in an image20:17
n4nd0I have googled it right now20:18
n4nd0it seems that it is used in gesture recognition20:18
n4nd0my guess:20:18
n4nd0the hidden states are the gestures themselves20:18
n4nd0the observation may be features extracted from images20:19
blackburnhmm that sounds interesting :)20:19
n4nd0blackburn: anyway, do you know if I can load from python *any* .mat file?20:19
blackburnn4nd0: sure you can20:19
blackburnscipy.io.loadmat20:19
n4nd0when I tried to load the ones generated by the hmsvm toolbox20:20
n4nd0I got some errors, but I was probably doing somethiing wrong20:20
blackburnerrors like?20:20
n4nd0mmm let me check20:20
n4nd0it was a couple of weeks ago when I tried this20:20
n4nd0I don't even have that code more20:21
n4nd0it was something very simple, 5-10 lines loading a module and trying to load the .mat file20:21
n4nd0importing a module, better20:21
blackburnI use .mat loading in my tester scripts and it works nice20:22
n4nd0is any of those in the repo?20:22
n4nd0using this from tools.load import LoadMatrix it didn't work out well20:22
blackburnn4nd0: use scipy.io.loadmat20:25
blackburnn4nd0: it returns dictionary matlab_name -> value20:28
n4nd0blackburn: nice!20:29
n4nd0I could get it to work20:29
n4nd0thank you very much :)20:29
n4nd0ok, I am going to take a break now to have dinner and see the games20:30
n4nd0see you later!20:30
blackburnn4nd0: :) see you20:30
