Artificial Immune Systems are a new class of algorithms inspired by how the immune system recognizes, attacks and remembers intruders. This is a fascinating idea, but to be accepted for mainstream data mining applications, extensive benchmarking is needed to demonstrate the reliability and accuracy of these algorithms. In our research we focus on the AIRS(More)
We describe a model for estimating the customer lifetime value (CLV) of customers in an e-commerce environment. The model is explained and experiments are performed on real-life data from a large Dutch Internet retailer. Our method results in CLV estimates that have similar accuracy to estimates generated by the commonly used model, while keeping the(More)
This paper outlines the approach developed together with the Radio Network Strategy & Design Department of a large telecom operator in order to forecast the Air-Interface load in their 3G network, which is used for planning network upgrades and budgeting purposes. It is based on large scale intelligent data analysis and modeling at the level of thousands of(More)
