Extremely fast evaluation of the extrinsic clustering measures: *various F1 measures (including F1-Score) for overlapping multi-resolution clusterings with unequal node base (and optional node base synchronization)* and standard NMI for non-overlapping clustering on a single resolution. | ||
`xmeasures` evaluates F1 and NMI for collections of hundreds thousands clusters withing a dozen seconds on an ordinary laptop using a single CPU core. The computational time is O(N) unlike O(N*C) of the existing state of the art implementations, where N is the number of nodes in the network and C is the number of clusters. | ||
`xmeasures` is one of the utilities designed for the [PyCaBeM](https://github.com/eXascaleInfolab/PyCABeM) clustering benchmark to evaluate clustering of large networks. | ||
A paper about the implemented F1 measures (F1p is much more discriminative than the standard F1-Score, NMI measures and their applicability is being written now and the reference will be specified before Summer, 2017. | ||
A paper about the implemented F1 measures (F1p is much more discriminative than the standard [Average F1-Score](https://cs.stanford.edu/people/jure/pubs/bigclam-wsdm13.pdf)), [NMI measures](www.jmlr.org/papers/volume11/vinh10a/vinh10a.pdf) and their applicability is being written now and the reference will be specified before Summer, 2017. | ||
> Standard NMI is implemented considering overlapping and multi-resolution clustering only to demonstrate non-applicability of the standard NMI for such cases, it yield unfair results. See [GenConvNMI](https://github.com/eXascaleInfolab/GenConvNMI) for the fair generalized NMI evaluation. | ||
