The results of experiments confirm that, for some decision problems, our proposition allows us to obtain a classifier with the same quality as a classifier obtained without cost limit but its exploitation is cheaper. 展开 关键词: decision tree cost-sensitive classifier cost limit ...
But the development cost for an aircraft is frequently many times the cost for a ship, in some cases one to two orders of magnitude greater (DDG 51 development cost $3B, F22 development cost $30B). This paper first examines and compares the top-line development costs for a broad range ...

ceranae infection did not differ significantly between colonies (F22,1 = 1.36, P = 0.256). Sexual transmission: insemination with parasite spores. No Nosema was detected in any of the tissue samples (spermatheca, ovary, gut) from any of the control queens that had been...
Causal modelling of semiconductor fabrication Semiconductor fabrication is the manufacturing process by which wafers of silicon are turned into integrated circuits. Reasoning about how wafers are affected by fabrication operations is an important aspect in getting computers to aid i... SJ Mohammed - 《...
Male migratory birds tend to be more faithful than females to previous breeding sites, suggesting sex differences in costs or benefits of dispersal. In Illinois, greater site fidelity by male yellow-headed blackbirds ( Xanthocephalus xanthocephalus ) was associated with reduced reproductive success th...
