Did you try the scikit-learn's implementation of DBSCAN:

Thanks Chris. So I guess the question becomes how can I efficiently
cluster 1 million x,y coordinates.

Hey Guys
I am new to both python and more so to numpy. I am trying to cluster
close to a 900K points using DBSCAN algo. My input is a list of ~900k
tuples each having two points (x,y) coordinates. I am converting them
to numpy array and passing them to pdist method of
scipy.spatial.distance for ca

To elaborate on what Fred said, in Theano we try to offer the same
functions/methods as NumPy does with the same arguments and same b

Ah! I see what you mean, or so I think. So the first time a weave
based code runs, it builds, stores the c

you could write Blitz++ code, and call it from Cython. That may be a
bit klunky at this point,

Hi,
I'm looking for the entry point in Numpy doc for the percentile function.
I'm assuming it should sit in routines.statistics but do not see it :
http://docs.scipy.org/doc/numpy/reference/routines.statistics.html
Am I missing something ? If indeed the percentile entry should be added,

I don't know for the stability, but for the existence of this new parameter:
