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。

Excess wind power produced in wind-intensive areas is normally delivered to remote load centers via long-distance transmission lines. This paper presents a comparison between long-distance transmission, which has gained popularity, and local energy consumption, in which a fraction of the generated wind power can be locally consumed by energy-intensive industries. First, the challenges and solutions to the long-distance transmission and local consumption of wind power are presented. Then, the two approaches to the utilization of wind power are compared in terms of system security, reliability, cost, and capability to utilize wind energy. Finally, the economic feasibility and technical feasibility of the local consumption of wind power are demonstrated by a large and isolated industrial power system, or supermicrogrid, in China. The coal-fired generators together with the short-term interruptible electrolytic aluminum load in the supermicrogrid are able to compensate for the intermittency of wind power. In the long term, the transfer of high-energy-consumption industries to wind-rich areas and their local consumption of the available wind power are beneficial.

Billet optimization can greatly improve the forming quality of the transitional region in the isothermal local loading forming (ILLF) of large-scale Ti-alloy rib-web components. However, the final quality of the transitional region may be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billet, fluctuation of the stroke length, and friction factor. Thus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to address the uncontrollable factors in transitional region of the ILLF. Given that the die underfilling and folding defect are two key factors that influence the forming quality of the transitional region, minimizing the mean and standard deviation of the die underfilling rate and avoiding folding defect were defined as the objective function and constraint condition in robust optimization. Then, the cross array design was constructed, a dual-RSM model was established for the mean and standard deviation of the die underfilling rate by considering the size parameters of the billet and uncontrollable factors. Subsequently, an optimum solution was derived to achieve the robust optimization of the billet. A case study on robust optimization was conducted. Good results were attained for improving the die filling and avoiding folding defect, suggesting that the robust optimization of the billet in the transitional region of the ILLF was efficient and reliable.
