This paper introduces gain-cost classi cation matrix for targeting customer groups. A real life application was realized on a customer database of CCF Bank containing more than 400,000 instances. Results shows that scoring is almost insensitive to di¤erent cost-gain hypothesis; on the other hand, the optimal targeted group size and the expected global bene t rely to cost-gain hypothesis. Keywor...
I frequently nd economists who express a view of the system that is very far from mine. For example, many young economists and economics students say that they expect to get no bene ts at all from Social Security. This expectation does not seem sensible to me. If there is no legislation changing Social Security, trust fund assets and payroll tax revenue (and revenue from the taxation of bene...
In distributed query processing the conventional approach to reduce the amount of data transmission is to rst apply a sequence of semijoins as reducers and then ship the resultant relations to the nal site to carry out the join operations Recently it has been shown that the approach of applying a combination of joins and semijoins as reducers can lead to substantially larger reduction on data t...
The most natural, compositional, way of modeling real-time systems uses a dense domain for time. The satissability of timing constraints that are capable of expressing punctuality in this model, however, is known to be undecidable. We introduce a temporal language that can constrain the time diierence between events only with nite, yet arbitrary, precision and show the resulting logic to be EXP...
The economics of managing disease transmission at the wildlife–livestock interface have received heightened attention as agricultural and natural resource agencies struggle to tackle growing risks to animal health. In the scal landscape of increased scrutiny and shrinking budgets, resource managers seek to maximize the bene ts and minimize the costs of disease mitigation efforts. To address thi...
The 1988 paper, \The Limited Performance Bene ts of Migrating Active Processes for Load Sharing," by Eager, Lazowska and Zahorjan concludes that migrating active processes for load balancing o ers little additional performance bene t beyond that obtained using only remote execution (placement). This result is based on analysis and simulation of a system model that is intended to overestimate th...
