Arrival cost- use weighted avg of trade price?CFA协会上给出的关于arrival cost的公式就是用平均成...
你说的没错，weighted average rate和average rate在本题其实已经不好比较了，所以维度１失效，我们可...

Thus it is not necessary to incur the high cost of an exact search. Our indexing method is a statistical approach that works in two steps. It first performs non-supervised clustering using Tree-Structured Vector Quantization (TSVQ) to group similar objects together. To maximize 10 efficiency, ...
C (6) Weighted extreme learning machine (WELM) The main viewpoint of WELM is to assign penalties to dif- ferent classes, and it can be view as a cost sensitive version of ELM in handling the troublesome imbalanced data problem. In the WELM, the penalty factor C is added to the ELM ...
In Table 5, Table 6, Table 7, for each SLS solver, ‘min.’ and ‘max.’ denote the minimum and maximum weight of unsatisfied soft clauses among all 10 runs, respectively, while ‘avg.’ denotes the averaged weight of unsatisfied soft clauses over all 10 runs; ‘time’ denotes the ...
However, the average gap of all the tested A-instances between the Best OFV and the Avg OFV of both scenarios is under 0.01%. Among different instances of the first scenario, instance A-k5-n39 had the highest gap between the Avg OVF and the Best OFV with 0.18%. In the second ...

3.3.4. Other statistical values for the Evolutionary and Metaheuristic method The influence of benchmark topologies and hardware (only for evolutionary algorithm) on selected parameters (Dif. ref-min (%), Dif. ref-avg (%) and coefficient of variation) can be seen in Table 12, Table 13 and...
