深度学习模型的广泛使用,在更大程度上使人们意识到模型的决策是亟需解决的问题,复杂难以解释的黑盒模型阻碍了算法在实际场景中部署。LIME作为最流行的局部解释方法,生成的扰动数据却具有不稳定性,导致最终的解释产生偏差。针对上述问题,提出了一种基于主动学习和二次有理核的模型无关局部解释方法ActiveLIME,使得局部解释模型更加忠于原始分类器。ActiveLIME生成扰动数据后,通过主动学习的查询策略对扰动数据进行采样,筛选不确定性高的扰动集训练,使用迭代过程中准确度最高的局部模型对感兴趣实例生成解释。并且,针对容易陷入局部过拟合的高维稀疏样本,在模型损失函数中引入了二次有理核来减少过拟合。实验结果表明,所提出的ActiveLIME方法引比传统局部解释方法具有更高的局部保真度和解释质量。

MOF-based core-shell structures with high surface area, abundant active sites, and broad absorption bands are viable alternatives to traditional single-component photocatalysts. In this report, we describe the design and construction of delicate Ag nanowires@NH_(2)-UiO-66 with a core-shell structure for use as photocatalysts in imine synthesis under light. The optimized composites exhibited 80% imine production, which was higher than both MOF and Ag NWs. The significant improvement in photocatalytic activity under light may be attributed to the plasmonic effect of silver nanowires and their core-shell structure, which promotes the separation of electron-hole pairs. Moreover, the photocatalytic activity of the core-shell nanostructure may provide valuable insight into the design and construction of MOF-based composite photocatalysts for oxidative coupling of amines.
