How to Train Single-Object Recognition?

I was thinking of doing a little project that involves recognizing simple two-dimensional objects using some kind of machine learning. I think it's better that I have each network devoted to recognizing only one type of object. So here are my two…

which (machine learning) method to recognize an unsteady moving 3D structure in multivariate time series?

Let's assume I have local measurements of the temperature, wind speed, air pressure, humidity and so on, in the form of time series, and thats all I know from the world. From time to time, a tornado goes over my probe. Because a tornado is not just…

Word classification in Pybrain: Different number of sequences in input vectors

I'm trying to implement a simple single digit classifier using PyBrain. I have training data of many recorded examples of the digits zero to nine, and have written a script to extract MFCCs for each example. To keep things simple (for now) I'm only…

Trouble with the scope of variables in a class?

So I'm in the process of making a class in Python that creates a network (with pybrain) using solely the numeric input it's given {just a little process to get my feet wet in Pybrain's API}. My problem is, I'm rather unfamiliar with how scopes work…

Matching Binary operators in Tuples to Dictionary Items

So, I'm working on a Pybrain-type project and I'm stuck on part of it. So far the program takes in a tuple and assigns a variable to it using 'one of them fancy vars()['string'] statements. Specifically, it takes in a tuple of numbers and assigns…
