鉴于元学习在众多领域取得的巨大成就,本文针对数据回归问题提出了融合度量学习和神经网络(NN)的局部二次嵌入学习(LQEL)算法。首先,通过优化输入输出空间里样本间度量的全局一致性来改进马氏度量(Mahalanobis metric)学习算法;同时,通过引入松弛约束进一步证明了改进的度量学习问题等价于一个凸规划问题。然后,基于局部二次插值假设原理,引入了两个轻量级的神经网络,其一用于学习局部二次模型中的系数矩阵,另一个则用于对从不同局部近邻获得的预测结果进行权重分配。最后,将两个子模型嵌入统一的回归框架中,并通过随机梯度下降(SGD)算法学习模型参数。所提出的算法优势在于可充分利用目标标签中隐含的信息找到更可靠的参考样本。并且,使用LQEL算法对变量进行差分建模,避免了因传感器漂移或不可测量变量导致的模型退化问题。多个基准数据集和两个实际工业应用数据集的计算结果表明,所提出的方法优于几种典型的回归方法。

Kernel texture (grain hardness) is a fundamental and determining factor related to wheat ( spp.) milling, baking and flour utilization. There are three kernel texture classes in wheat: soft and hard hexaploid ( ), and very hard durum ( subsp. ). The genetic basis for these three classes lies with the Puroindoline genes. Phenotypically, the easiest means of quantifying kernel texture is with the Single Kernel Characterization System (SKCS), although other means are valid and can provide fundamental material properties. Typical SKCS values for soft wheat would be around 25 and for durum wheat≥80. Soft kernel durum wheat was created via homeologous recombination using the mutation, which facilitated the transfer of ca. 28 Mbp of 5DS that replaced ca. 21 Mbp of 5BS. The 5DS translocation contained a complete and intact locus and both puroindoline genes. Expression of the puroindoline genes in durum grain resulted in kernel texture and flour milling characteristics nearly identical to that of soft wheat, with high yields of break and straight-grade flours, which had small particle size and low starch damage. Dough water absorption was markedly reduced compared to durum flour and semolina. Dough was essentially unchanged and reflected the inherent gluten properties of the durum background. Pasta quality was essentially equal-to-or-better than pasta made from semolina. Agronomically, soft durum germplasm showed good potential with moderate grain yield and resistance to a number of fungal pathogens and insects. Future breeding efforts will no doubt further improve the quality and competitiveness of soft durum cultivars.

关键性能指标(KPI)的软测量在复杂工业过程决策中起着至关重要的作用。许多研究人员已经使用先进的机器学习(ML)或深度学习(DL)模型开发出了数据驱动的软传感器。其中,特征选择是一个关键的问题,因为一个原始的工业数据集通常是高维的,并不是所有的特征都有利于软传感器的建立。一种完善的特征选择方法不应该依赖于超参数和后续的ML或DL模型。换言之,这种特征选择方法应该能够自动地选择一个特征子集进行软传感器建模,选择的每个特征对工业KPI 都有独特的因果影响。因此,本研究提出了一种受因果模型启发的自动特征选择方法,用于工业KPI 的软测量。首先,受后非线性因果模型的启发,本研究将数据驱动的软传感器与信息论相结合,以量化原始工业数据集中每个特征和KPI之间的因果效应。然后,提出了一种新的特征选择方法,即自动选择具有非零因果效应的特征来构造特征子集。最后,利用所构造的子集,通过AdaBoost 集成策略开发KPI 的软传感器。两个实际工业应用中的实验证实了该方法的有效性。在未来,该方法也可以应用于其他工业过程,以帮助开发更先进的数据驱动的软传感器。
