Performance is measured by the mean (Avg.) and standard deviation (Std.) of optimal solutions, with Avg assessing global and local search capabilities, and Std evaluating robustness. The IEEE CEC2017 functions are selected for testing CCHSMA, with additional statistical comparisons using Friedman's...
To the RFR, we add the debt spread associated with the debt rating on the company’s long-term debt. The resulting pre-tax cost of debt is then multiplied by (1 – marginal tax rate). If a company fails to generate a return on invested capital (ROIC) greater than its WACC, it is ...
This strategy has been proven effective in previous studies such as LW-ELM [30] and BLW-ELM [31], which belongs to cost-sensitive methods. In this subsection, a novel label imbalance weighting strategy is proposed to improve the attention of BLS to minority class samples, which is introduced...
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 ...

Unfortunately, this method is not suitable for large-scale social network graphs for its huge computational cost. Thus, we will no longer consider it. 4.1. Local Extend Algorithm The intuitive algorithm is essentially the enumeration of graphs starting from 𝑞q, resulting in massive invalid ...
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...
First, we retain transverse skip-scale connections used in BiFPN for the same-level feature reuse while avoiding adding much cost. Second, to enhance semantic interactions between features of different resolutions, two types of longitudinal skip-scale connections are added in the bi-directional ...
