知识技能对薪酬影响作用视为一种多变量影响下高维元素集合的效用建模问题.深度神经网络为解决复杂问题提供了新的机遇,但针对知识导向的细粒度薪酬预测问题,仍缺乏能够对复杂变量影响下的集合效用进行准确、可解释建模的神经网络结构.为此,提出一种基于边际贡献的增量式集合效用网络(marginal contribution-based incremental set utility network,MCISUN)来拟合元素加入时的效用增量,从而灵活且可解释地建模集合效用.区别于以往基于池化层的排列不变性建模算法,MCISUN构建顺序敏感的中间结果,利用集合的排列不变性实现数据增强,有效提升模型数据效率及泛化性.最后,大规模真实薪酬数据上的实验结果表明所提模型在基于技能的薪酬预测任务上比最先进的(state-of-the-art,SOTA)模型效果提升超过30%.同时,定性实验证明模型能够为技能设置合理的贡献值且发现技能间的关联.

The aim of this paper was to address the effect of laser shock processing (LSP) on the microstructure of ultrafine-grained commercially pure aluminium which was produced through severe cold rolling and annealing. The microstructure characteristics of ultrafine-grained commercially pure aluminium were experimentally investigated by TEM during ultra-high strain rate loading. The results show that microstructure was obviously refined due to ultra-high plastic strain induced by a single pass LSP impacts. The grain sizes decrease from 0.6 μm after severe cold rolling and annealing to 0.3 μm at the center of the laser shock wave after a single pass LSP. There is a distinct increase in the dislocation density at the edge of the laser shock wave. These experiments have guide meaning to the practical engineering applications of LSP technique.
