Thanks Timmy, If you could also include in the gist a minimal python script which reproduces the error from the included data, that would be very helpful. Jake Timmy Wilson wrote: > Thanks Jake > > here are the files -- https://gist.github.com/1453617 > > here's the code creating the input data

If you have a github account, you could create a gist: https://gist.github.com/ This results in a sort of temporary git repository you can push files to as with any git repository. If you push your data file and python code you use to process and plot it, I can take a look and see if I can figure

Is this essentially agent based modeling? Not exactly the same, but i think this paper touches on the essence of the method: " Their internal states are governed by finite state machines, but their external relationships are governed by a simulated physics that includes Brownian motion, viscosity

Hi All ! I plan on also working on scikit learn during this time, but from France. I'd like to implement the HAP, the hierarchical version of the affinity propagation during that time. On 8 December 2011 15:27, Mathieu Blondel wrote: > Hi everyone, > > I've edited the wiki with ideas for the two

I first ran into energy-based learning when studying neural nets. Recently i found a few promising papers/examples that focus on energy based graph embedding. I'm curious what the community thinks of this brand of learning? The guys @ Gephi published a nice overview of force/energy

Ok as nobody expressed hard concerns w.r.t. dropping support for python 2.5, I think we can make that decision official now and close this vote. So let's officially support python 2.6, scipy 0.7.2 and numpy 1.3.0 from now on. I will try to find the time to setup a jenkins build + tests reflecting
