摘要： Open information extraction (Open IE), as one of the essential applications in the area of Natural Language Processing (NLP), has gained great attention in recent years. As a critical technology for building Knowledge Bases (KBs), it converts unstructured natural language sentences into structured representations, usually expressed in the form of triples. Most conventional open information extraction approaches leverage a series of manual pre-defined extraction patterns or learn patterns from labeled training examples, which requires a large number of human resources. Additionally, many Natural Language Processing tools are involved, which leads to error accumulation and propagation. With the rapid development of neural networks, neural-based models can minimize the error propagation problem, but it also faces the problem of data-hungry in supervised learning. Especially, they leverage existing Open IE tools to generate training data, and it causes data quality issues. In this paper, we employ a distant supervision learning approach to improve the Open IE task. We conduct extensive experiments by employing two popular sequence-to-sequence models (RNN and Transformer) and a large benchmark data set to demonstrate the performance of our approach.

摘要： Network slicing (NS) management devotes to providing various services to meet distinct requirements over the same physical communication infrastructure and allocating resources on demands. Considering a dense cellular network scenario that contains several NS over multiple base stations (BSs), it remains challenging to design a proper real-time inter-slice resource management strategy, so as to cope with frequent BS handover and satisfy the fluctuations of distinct service requirements. In this paper, we propose to formulate this challenge as a multi-agent reinforcement learning (MARL) problem in which each BS represents an agent. Then, we leverage graph attention network (GAT) to strengthen the temporal and spatial cooperation between agents. Furthermore, we incorporate GAT into deep reinforcement learning (DRL) and correspondingly design an intelligent real-time inter-slice resource management strategy. More specially, we testify the universal effectiveness of GAT for advancing DRL in the multi-agent system, by applying GAT on the top of both the value-based method deep Q-network (DQN) and a combination of policy-based and value-based method advantage actor-critic (A2C). Finally, we verify the superiority of the GAT-based MARL algorithms through extensive simulations.

摘要： This article is concerned with a new generalized actor-critic learning (GACL) optimal control method. It aims at the optimal energy control and management for smart home systems, which is expected to minimize the consumption cost for home users. In the present GACL optimal control method, it is the first time that three iteration processes, which are global iteration, local iteration, and interior iteration, respectively, are established to obtain the optimal energy control law. The main contribution of the developed method is to establish a common iteration structure for both value and policy iterations in adaptive dynamic programming based on a control law sequence in each iteration for periodic time-varying systems, instead of a single control law, and simultaneously accelerates the convergence rate. The monotonicity, convergence, and optimality of the iterative value function for the GACL optimal control method are proven. Finally, numerical results and comparisons are displayed to show the superiority of the developed method.

摘要： Objective The purpose of this study was to explore how academic womxn experience their partnerships during quarantine and to determine the impact of those relational dynamics on scholarly productivity. Background Past literature indicates traumatic events and extended quarantine is associated with negative mental health outcomes. While primary partnerships serve as one protective factor, extended quarantine with one's partner introduces novel stress to a relationship, which may have unintended outcomes, including those that affect productivity. Method An online survey was provided to academic womxn invested in scholarship. Responses from participants who identified as in a relationship (n = 67) were coded using thematic analysis through a feminist lens. Findings Participants highlighted three major themes across their responses: time and space, communication, and needs. These findings reflected stressors typical within couple relationships but highlighted important considerations for partners of academic womxn in support of their scholarly activity during quarantine. Conclusion Though the flexibility available during the pandemic for academic womxn provided time and space for some to nurture their relationship as well as focus on scholar activity, this was not consistent across partners. Implications Findings show the mixed experiences of partners and confirm the importance of communication, especially about time and space and professional needs. Recommendations can be extrapolated to other processional and career partnerships.
