Good memo. Could I translate it to Russian and put it on my site for my students (with reference, of course) ?

Commands need some escaping, since — is dispalyed as long dash and “” are tranlated to literary quotes.

Hi, an open-source implementation of various dtw algorithms is available for R at http://dtw.r-forge.r-project.org . It has an extensive manual and is callable from Python. Should work well for rapid experimentation.

Hello rick wei,

As you suggest, I have provided input data for td and delta in train function, but I am getting error of objects are not aligned. Here is output of that

File “/var/test/seminb.py”, line 156, in train
self.p_w_c[w,c] += td[w,d] * delta[d,c]
File “/usr/lib/python2.6/dist-packages/numpy/core/defmatrix.py”, line 290, in __mul__
return N.dot(self, asmatrix(other))
ValueError: objects are not aligned

I am running it on ubuntu linux system.

Please advise what should i do to successfully run train and other functions.

I think the book is a great idea. I tried to do something similar for the Lisbon Machine Learning Summer School (http://lxmls.it.pt/Schedule.html) It’s under the practical implementation exercises. The ideia was to have a simple and practical book full of examples for students to practice what they learn in the morning lectures.
I intend to continue developing it for this year summer school, so maybe we could collaborate on it.
