基于专利分析概念模型的中国机器人技术发展预测

基于专利分析的概念模型,从技术发展方向、技术发展水平和技术发展潜力三个方面对中国机器人技术发展进行预测,以验证模型的应用性。预测结果表明：中国机器人整体技术处于成长期,但主要的子技术还存在明显差异：其中机械手子技术已位于成长期的中后期阶段,转向机构子技术则位于成长期的前期阶段,非电变量的控制或调节系统技术以及一般的控制或调节系统则刚进入成长期。因此,企业、高校以及科研院所应积极抓住机器人技术发展的大好时机,开展联合攻关,实现机器人关键技术的重大突破,促进产业转型与升级,提升先进制造业的产业技术竞争力。     

青海省东乘公麻金矿床Ⅵ号矿体原生晕特征及深部找矿预测

东乘公麻金矿床是青海省巴颜喀拉造山带北缘Au-Sb成矿带上新发现的中型金矿床,由于受“生态保护第一,尊重群众意愿”政策影响,勘查工作主要以深部勘查为主,本文选择该矿床有代表性的VI号矿体,研究其构造原生晕轴向分带序列。研究结果表明：VI号矿体原生晕分带序列为：（Au、Sb、As）→（Bi、Pb）→（Ag、Cu、Zn）;分带序列呈现“反分带”趋势,地球化学参数“反转”,前、尾晕共存,预测VI号矿体深部延伸较好或有隐伏矿体存在的可能性,圈定了成矿靶区,以期为矿山下一步探矿工作提供科学依据。     

Prediction of stress levels in the workplace using surrounding stress

Occupational stress has a significant adverse effect on workers’ well-being, productivity, and performance and is becoming a major concern for both individual companies and the overall economy. To reduce negative consequences, early detection of stress is a key factor. In response several stress prediction methods have been proposed, whose primary aim is to analyse physiological and behavioural data. However, evidence suggests that solutions based on physiological and behavioural data alone might be challenging when implemented in real-world settings. These solutions are sensitive to data problems arising from losses in signal quality or alterations in body responses, which are common in everyday activities. The contagious nature of stress and its sensitivity to the surroundings can be used to improve these methods. In this study, we sought to investigate automatic stress prediction using both surrounding stress data, which we define as close colleagues’ stress levels and the stress level history of the individuals. We introduce a real-life, unconstrained study conducted with 30 workers monitored over 8 weeks. Furthermore, we propose a method to investigate the effect of stress levels of close colleagues on the prediction of an individual’s stress levels. Our method is also validated on an external, independent dataset. Our results show that surrounding stress can be used to improve stress prediction in the workplace, where we achieve 80% of F-score in predicting individuals’ stress levels from the surrounding stress data in a multiclass stress classification.     

MTGCN: A multi-task approach for node classification and link prediction in graph data

Both node classification and link prediction are popular topics of supervised learning on the graph data, but previous works seldom integrate them together to capture their complementary information. In this paper, we propose a Multi-Task and Multi-Graph Convolutional Network (MTGCN) to jointly conduct node classification and link prediction in a unified framework. Specifically, MTGCN consists of multiple multi-task learning so that each multi-task learning learns the complementary information between node classification and link prediction. In particular, each multi-task learning uses different inputs to output representations of the graph data. Moreover, the parameters of one multi-task learning initialize the parameters of the other multi-task learning, so that the useful information in the former multi-task learning can be propagated to the other multi-task learning. As a result, the information is augmented to guarantee the quality of representations by exploring the complex constructure inherent in the graph data. Experimental results on six datasets show that our MTGCN outperforms the comparison methods in terms of both node classification and link prediction.
