I am interested in running Newman\'s modularity cluste开发者_如何学Cring algorithm on a large graph. If you can point me to a library (or R package, etc) that implements it I would be most grateful.
How can I do K-means clustering of time series data? I understand how this works when the input data is a set of points, but I don\'t know how to cluster a time series with 1XM, where M is the data le
In or开发者_如何转开发der to perform a simple clustering algorithm on results that I get from Lucene, I have to calculate Cosine similarity between 2 documents in Lucene, I also need to be able to mak
Problem Statement: I have the following problem: There are more than a billion points in 3D space. The goal is to find the top N points which has largest number of neighbors within given distance R.
I have hit a real problem. I need to do some Kmeans clustering for5 million vectors, each containing about 32 cols.
I have an ordered list of weighted items, weight of each is less-or-equal than N. I need to convert it into a list of clusters.

I\'m playing a little bit with image similarity. In fact i\'m playing with image retrieval system. Ideally i wanna to create some kind of image index that I can query to get similar images.
Assuming I have a list of shifts for an event (in the format start date/time, end date/time) - is there some sort of algorith开发者_如何学Gom I could use to create a generalized summary of the schedul
