Just musing bit: I wonder about the power of narrative.
I do not mean the narrative style of TV shows like CSI and NCIS where they can "enhance" a single pixel into a recognisable face or number plate - rather the narrative of a sequence of transactions. Can a sequence tell a story that leads to comprehension - or at least to reduced false positives?
We know that Bayesian SPAM filters need to keep track of the new stories arriving in our email in-boxes as the SPAM and fraud "pitches" evolve over time - seems to me we should be able to do something similar with transactions - we just need to find a narrative (or some other less than perfect understanding) in any given sequence.
Sequence can be essential. Ever see a picture on a camera and not be able to place it or decode it ... then if you look at the pictures before it and after it. Then sometimes this is the context you need? Yep - just like that!
