Data Mining, Down Under

Earlier in the month local data miner Tim Manns presented at the Sydney Data Miners group.  Tim spoke on some work been doing at Optus around using mobile call patterns to establish social networks and using these networks to reduce customer churn.  Interestingly, there are also applications in many other areas, including data cleansing, for example, where one person has purchased two mobile phones and given one to their spouse or child.  Using this analysis we can try to determine which account is likely to be the actual account holder and infer the details (such as age) of the other customer.
