现有的方法将通过张量奇异值分解(t-SVD)正则化的低秩表示应用到多视图子空间聚类中,取得了令人印象深刻的聚类性能.然而,它们都具有以下两个共同的缺点:(1)他们专注于探索样本之间的关系以构建表征,然后将其堆叠为张量,其计算复杂度至少为O(n2logn);(2)他们总是直接在整合的表征上运行标准的谱聚类算法,而忽略了不同表征对最终聚类结果的先验知识.为了解决这些问题,本文提出了一种新颖的张量学习诱导的多视图谱聚类(TLIMSC)方法,其中同时探索了空间聚类结构和互补信息.具体来说,该方法将关联样本和簇关系的多视图谱嵌入表示堆叠成张量,计算复杂度最终变为O(n logn).然后,将学习到的带有不同自适应置信度的表征与最终的一致聚类结果联系起来.在五个数据集上的广泛实验证明了TLIMSC所具有的有效性和高效性.

宜商环境评价体系中新增了“劳动力”作为新的评价指标,对“劳动力”指标的考量离不开我国劳动法律制度的完善和落实。以《劳动法》《劳动合同法》为代表的劳动法律制度并非如一些学者和媒体所宣称的那样只有负面作用。虽然有些法律条文侧重于保护劳动者的合法权益,但整体上我国劳动法是保护劳动者利益同时也保护资方利益的制度,是在综合考量劳资双方利益的基础上对劳动者权益的侧重保护,并非所谓的对劳动者权益的单方面保护。从长远看,劳动法甚至是更多地保护了资方利益的法律,对优化宜商环境、保护生产要素、构建和谐稳定的劳动关系等都有明显的效益。

In the ongoing evolutionary process, biological systems have displayed a fundamental and remarkable property of robustness, i.e., the property allows the system to maintain its functions despite external and internal perturbations. Redundancy and degeneracy are thought to be the underlying structural mechanisms of biological robustness. Inspired by this, we explored the proximate cause of the immunity of the synthetic evolved digital circuits to ESD interference and discussed the biological characteristics behind the evolutionary circuits. First, we proposed an evolutionary method for intrinsic immune circuit design. The circuits＇ immunity was evaluated using the functional fault models based on probability distributions. Then, several benchmark circuits, including ADDER, MAJORITY, and C17, were evolved for high intrinsic immunity. Finally, using the quantitative definitions based on information theory, we measured the topological characteristics of redundancy and degeneracy in the evolved circuits and compar.d their contributions to the immunity. The results show that redundant elements are neces- sary for the ESD immune circuit design, whereas degeneracy is the key to making use of the redundancy robustly and efficiently.

为快速获取单分蘖水稻植株的形态结构和表型参数,该研究提出了一种基于目标检测和关键点检测模型相结合的骨架提取和表型参数获取方法。该方法基于目标检测模型生成穗、茎秆、叶片的边界框和类别,将所得数据分别输入到关键点检测模型检测各部位关键点,按照语义信息依次连接关键点形成植株骨架,依据关键点坐标计算穗长度、茎秆长度、叶片长度、叶片-茎秆夹角4种表型参数。首先,构建单分蘖水稻的关键点检测和目标检测数据集;其次,训练Faster R-CNN、YOLOv3、YOLOv5s、YOLOv5m目标检测模型,经过对比,YOLOv5m的检测效果最好,平均精度均值(mean average precision,mAP)达到91.17%;然后,应用人体姿态估计的级联金字塔网络(cascaded pyramid network,CPN)提取植株骨架,并引入注意力机制CBAM(convolutional block attention module)进行改进,与沙漏网络(hourglass networks,HN)、堆叠沙漏网络模型(stacked hourglass networks,SHN)和CPN模型相比,CBAM-CPN模型的预测准确率分别提高了9.68、8.83和1.06个百分点,达到94.75%,4种表型参数的均方根误差分别为1.06 cm、0.81 cm、1.25 cm和2.94°。最后,结合YOLOv5m和CBAM-CPN进行预测,4种表型参数的均方根误差分别为1.48、1.05、1.74cm和2.39°,与SHN模型相比,误差分别减小1.65 cm、3.43 cm、2.65 cm和4.75°,生成的骨架基本能够拟合单分蘖水稻植株的形态结构。所提方法可以提高单分蘖水稻植株的关键点检测准确率,更准确地获取植株骨架和表型参数,有助于加快水稻的育种和改良。
