Do note that the digit dataset(MNIST) you used to train the classifier consists of hand-written digits, while the dataset you used in testing consists of machine generated digits. It is like learning to read English by learning German, it might work to some extent but not much. You might be inte

Sure, here is example with 50 sample digits: http://nbviewer.ipython.org/gist/klonuo/b67789dc9fbea47633ac As mentioned I'll try later today to learn something from Andy's blog post and report back if I have anything. Cheers On Sat, May 24, 2014 at 9:22 AM, Ronnie Ghose wrote: > is it possible

is it possible for you to upload a subset of your digits? On Sat, May 24, 2014 at 2:52 AM, klo uo wrote: > Hi, > > thanks for your reply. > > 1. I tested about 100 samples with sklearn. In my example there was only > one sample because of readability and simplicity. > > In short: I read image w
