My attempt at a digit recognizer for a www.kaggle.com competition.

First solution:
Create path around character and create two 'time-series' of x- and y-positions for each step. Compare the time series of each test digit with the time series of the training digits via dynamic time warping (DTW) methods.
~30% and very slow
Second solution:
Simple logistic regression approach based on identifying digit features.
