متن کاملIeee Transactions on Pattern Analysis and Machine Intelligence
The role of moments in image normalization and invariant pattern recognition is addressed. The classical idea of the principal axes is analyzed and extended to a more general definition. The relationship between moment-based normalization, moment invariants, and circular harmonics is established. Invariance properties of moments, as opposed to their recognition properties, are identified using ...

متن کاملTime Graph Pattern Mining for Network Analysis and Information Retrieval
Graph pattern mining has played important roles in network analysis and information retrieval. However, temporal characteristics of networks have not been estimated sufficiently. We propose time graph pattern mining as a new concept of graph mining reflecting the temporal information of a network. We conduct two case studies of time graph pattern mining: extensively discussed topics on blog sit...
متن کاملElectronic Money Laundering Detection in Transactions of Payment Service Providers
Under the coverage of legitimate commerce, criminals money-launder their illicit incomes through the payment gateways provided by Payment Service Providers (PSP). In order to do money-laundering forensics in transactions of PSP companies, a new method was proposed by Hojati et al which is done through detecting deviations from class behavior based on peer group analysis (PGA) method. Our experi...

In the above correspondencel a maximum likelihood method is proposed for "estimating" class memberships and underlying statistical parameters, within the context of distribution mixtures. In the present comment it is pointed out that biases are incurred in parameter estimation, that the class memberships and parameters are conceptually different, and therefore that the so-called standard mixtur...
