Dear Luca and others,
Logarithm of probability bit-costing can be used for cluster
validation, decision tree/graph error rates and all sorts of validations
and measurements of error.
For more information, see section 6 of
Y. Agusta and D. L. Dowe (2003b). Unsupervised Learning of Correlated
Multivariate Gaussian Mixture Models using MML, (to appear) In Proc.
16th Australian Joint Conference on Artificial Intelligence (AI'03),
Perth, Australia, 3-5 Dec. 2003
(downloadable from
http://www.csse.monash.edu.au/~dld/Publications/2003/Agusta+Dowe2003b.ref )
and possibly also section 5.1 and table 3 of
P. J. Tan and D. L. Dowe (2003). MML Inference of Decision Graphs
with Multi-Way Joins and Dynamic Attributes, (to appear) In Proc.
