Development of neural network model based on attention mechanism applied to the prediction of ship damaged stability 基于注意机制的神经网络模型在船舶损伤稳定性预测中的应用
Haoqing Li, Xiaohao Huang, C. Pan, Chunlei Yang, Jinbao Wang
As a key indicator in ship design, many major incidents of ship sinking are related to the ship's damaged stability. The process of calculating the damaged stability becomes more and more complex and time-consuming on account of more and more stringent specification standards. A two-stage design step is used in this article to realize the calculation of ship’s damaged stability under various watertight bulkhead fast. Firstly, a multi-layer feed-forward neural network model was designed for the predictive regression of a ship's damaged stability using the location of the watertight bulkhead as a variable. Secondly, the relationship between each watertight bulkhead variant and the damaged stability A-value is analyzed. After that, with hydrostatic curve calculation based on the inlet simulation and the interaction between watertight bulkheads considered, a multilayer feed-forward neural network model based on the attention mechanism is designed, which could predict the regression of the damaged stability A-value and analyze bulkhead weights. Finally, the validity of the model was verified by the data, in which the mean value of the prediction error MAE (mean absolute error) was at 2.67×10-4 and the computation time was greatly reduced.
作为船舶设计的一项重要指标,许多重大的船舶沉没事故都与船舶的失稳性有关。由于规范标准的日益严格,破坏稳定的计算过程变得越来越复杂和耗时。本文采用两阶段设计方法,快速实现了不同水密舱壁条件下船舶损伤稳性的计算。首先,以水密舱壁位置为变量,设计了多层前馈神经网络模型,用于船舶损伤稳性的预测回归;其次,分析了水密舱壁各变型与破坏稳性a值的关系。在此基础上,考虑进气道仿真的静水曲线计算和水密舱壁之间的相互作用,设计了基于注意机制的多层前馈神经网络模型,预测了破坏稳定a值的回归,分析了舱壁重量。最后,通过数据验证了模型的有效性,其中预测误差MAE(平均绝对误差)的平均值为2.67×10-4,大大减少了计算时间。

Reinforcement learning multi-hop reasoning method with GAN network 基于GAN网络的强化学习多跳推理方法
Zhicai Gao, Xiaoze Gong, Yongli Wang
At present, the academic community has carried out some research on knowledge reasoning using Reinforcement Learning (RL), which has achieved good results in multi-hop reasoning. However, these methods often need to manually design the reward function to adapt to a specific dataset. For different datasets, the reward function in RL-based methods needs to be manually adjusted to obtain good performance. To solve this problem, an agent training model combined with Generative Adversarial Networks (GAN) is proposed. The model consists of two modules: a generative adversarial inference engine and a sampler. The sampler uses a policy-based bidirectional breadth-first search method to find the demonstration path, and the agent uses the reward considering the information of the neighborhood entities as the initial reward function. After sufficient adversarial training between the agent and the discriminator, the policy-based agent can find evidence paths that match the demonstration distribution and synthesize these evidence paths to make predictions. Experiments show that the model achieves better results in both fact prediction and link prediction tasks.
目前,学术界已经开展了一些利用强化学习(Reinforcement Learning, RL)进行知识推理的研究,并在多跳推理中取得了较好的效果。然而,这些方法通常需要手动设计奖励函数以适应特定的数据集。对于不同的数据集,基于强化学习的方法中的奖励函数需要手动调整才能获得良好的性能。为了解决这一问题,提出了一种结合生成式对抗网络(GAN)的智能体训练模型。该模型由两个模块组成:生成式对抗推理引擎和采样器。采样器采用基于策略的双向广度优先搜索方法寻找演示路径,agent采用考虑邻域实体信息的奖励作为初始奖励函数。策略智能体与判别器之间经过充分的对抗性训练后,可以找到与演示分布匹配的证据路径,并综合这些证据路径进行预测。实验表明,该模型在事实预测和链路预测任务中都取得了较好的效果。

Dongsheng Li, Bing Ma, Yuanzhong Ren, K. Li
In view of the large volume and complex structure of electromagnetic space big data, it is difficult to store and retrieve spectrum data using traditional databases and knowledge graph. Due to the abstractness and space-time characteristics of electromagnetic spectrum data, the use of event forms can better represent the spectrum data, and also make people and machines better understand. Based on the knowledge graph and the concept of events, this paper constructs the spectrum event knowledge graph (EMS-DEKG) and compares several methods of spectrum data retrieval through experiments, which shows that the EMS-DEKG method improves the stability and timeliness of electromagnetic space big data storage and retrieval.

Juan Fang, Qiangang Zheng, Wei-ming Liu, Haibo Zhang
With the development of Reinforcement Learning (RL), it becomes able to solve the continuous action space problem and shows strong ability in dealing with complex nonlinear control problem. Based on the Deep Deterministic Policy Gradient (DDPG) algorithm, a novel scheme of aeroengine acceleration controller is proposed in this paper. According to the characteristics of the engine acceleration stage, the reward function is constructed, and the state parameters are updated in the form of sliding window to reduce the sensitivity of the network to noise. DDPG adopts actor-critic framework, critic calculates value function by the deep neural network, actor outputs action command and forms a closed-loop control system with the engine. The method is verified by digital simulation at ground condition and the results demonstrate that compared with the traditional PID controller, the acceleration time of DDPG controller is reduced by 41.56%. Additionally, the network converges within 400 steps.

Pin Gao, Hongming Bian, Y. Bao
Chinese pattern design has not only witnessed the history of more than 5,000 years in China, but also impacted the aesthetic cognition of the East in the West. Chinese patterns have been beautiful since ancient times. In the past, it was created by the wisdom and hard work of the Chinese people, and now it should be inherited by the wisdom and hard work of the Chinese people. For the visualization platform of Chinese pattern design, better construction and improvement are needed. Therefore, in order to visualize information and achieve better results, if the memory occupancy is too high, the operation effect of the platform will be reduced. In order to improve the operation effect of the visualization platform, the construction of visual virtual reality platform of Chinese pattern design is proposed. Based on B/S mode, the software structure is established, and specific analysis is carried out, and the functional plate and visual effect design are improved. Through hardware and software design, the visual virtual reality platform of Chinese pattern design is constructed.

Bobo Guo, Zanxia Qiang, Xianfu Bao, Yao Xu
Lane detection is a crucial environmental sensing technique that is used in advanced driving assistance systems and automatic driving. The research on this issue has significant practical value. Aiming the current lane detection algorithm could not solve the problems of the local receptive field and detail feature loss, we introduced the multi-head self-attention module in Transformer into the encoder and decoder to obtain the global receptive field while solving the problem of detail feature loss with the multi-level feature fusion decoder. The proposed algorithm has been compared with the ERFNet model in the CULane dataset, and the detection accuracy has improved by 3.9 percentage points. The detection accuracy in the Tusimple dataset is 96.51%. Introducing a multi-head self-attention module increases the feature selection effect of the attention mechanism in the coding and decoding process. It provides a new solution for the lane detection algorithm.

Sleep is the life instinct of human beings. It is not only of great significance to the physical and mental health of individuals, but also can be used as a natural means of regulating, restoring and enhancing bodily functions. There is a prominent contradiction between health needs and the backward status of daily sleep health management, and there is an urgent need to develop theories and methods from sleep structure conversion mechanism to sleep quality monitoring and intervention. In the past few years, artificial intelligence (AI) technology has rapidly emerged in the field of sleep medicine. The purpose of this article is to provide a brief overview of relevant terms, definitions and use cases of artificial intelligence in sleep medicine. AI has a variety of applications in sleep medicine, including sleep and respiratory event scoring in sleep labs, diagnosis and management of sleep disorders, and population health. Although still in its infancy, there are still challenges that hinder the ubiquity and broad clinical application of AI. Overcoming these challenges will help seamlessly integrate AI into sleep medicine and enhance clinical practice. AI is a powerful tool in healthcare that can improve patient care, enhance diagnostic capabilities, and enhance the management of sleep disorders. However, before existing machine learning algorithms can be incorporated into sleep clinics, these artificial intelligence devices need to be regulated and standardized.
睡眠是人类的生命本能。它不仅对个人的身心健康具有重要意义,而且可以作为调节、恢复和增强身体机能的天然手段。健康需求与日常睡眠健康管理落后的现状之间矛盾突出,迫切需要从睡眠结构转化机制到睡眠质量监测与干预等方面发展理论和方法。近年来,人工智能(AI)技术在睡眠医学领域迅速兴起。本文的目的是简要概述人工智能在睡眠医学中的相关术语、定义和用例。人工智能在睡眠医学中有多种应用,包括睡眠实验室的睡眠和呼吸事件评分,睡眠障碍的诊断和管理,以及人群健康。尽管人工智能仍处于起步阶段,但仍存在阻碍其普及和广泛临床应用的挑战。克服这些挑战将有助于将人工智能无缝整合到睡眠医学中,并加强临床实践。人工智能是医疗保健领域的强大工具,可以改善患者护理,增强诊断能力,并加强对睡眠障碍的管理。然而,在现有的机器学习算法被纳入睡眠诊所之前,这些人工智能设备需要被规范和标准化。
