After two “cold winters of artificial intelligence”, machine learning has once again entered the public’s vision in recent ten years, and has a momentum of rapid development. It has achieved great success in practical applications such as image recognition and speech recognition system. It is one of the main tasks and objectives of machine learning to summarize key information and main features from known data sets, so as to accurately identify and predict new data. From this perspective, the idea of integrating machine learning into climate prediction is feasible. Firstly, taking the adjustment of linear fitting parameters (i.e. slope and intercept) as an example, this paper introduces the process of machine learning optimizing parameters through gradient descent algorithm and finally obtaining linear fitting function. Secondly, this paper introduces the construction idea of neural network and how to apply neural network to fit nonlinear function. Finally, the framework principle of convolutional neural network for deep learning is described, and the convolutional neural network is applied to the return test of monthly temperature in winter in East Asia, and compared with the return results of climate dynamic model. This paper will help to understand the basic principle of machine learning and provide some reference ideas for the application of machine learning to climate prediction.
在经历了两次“人工智能寒冬”后,近十年来,机器学习再次进入公众视野,并呈现出快速发展的势头。它在图像识别和语音识别系统等实际应用中取得了巨大成功。从已知数据集中总结关键信息和主要特征,从而准确识别和预测新数据,是机器学习的主要任务和目标之一。从这个角度来看,将机器学习融入气候预测的想法是可行的。首先,以线性拟合参数(即斜率和截距)的调整为例,介绍了机器学习通过梯度下降算法优化参数并最终获得线性拟合函数的过程。其次,介绍了神经网络的构造思想以及如何应用神经网络拟合非线性函数。最后,描述了卷积神经网络用于深度学习的框架原理,并将其应用于东亚冬季月气温的回归测试,并与气候动态模型的回归结果进行了比较。本文将有助于理解机器学习的基本原理,并为机器学习在气候预测中的应用提供一些参考思路。

Fractional PID controller is a convenient fractional structure that has been used to solve many problems in automatic control. The fractional scale proportional-integral-differential controller is a generalization of the integer order PID controller in the complex domain. By introducing two adjustable parameters  and , the controller parameter tuning range becomes larger, but the parameter design becomes more complex. This paper presents a new method for the design of fractional PID controllers. Specifically, the parameters of a fractional PID controller are optimized by a particle swarm optimization algorithm. Our simulation results on cold rolling APC system show that the designed controller can achieve control accuracy higher than that of a traditional PID controller.

A Study of Neural Machine Translation from Chinese to Urdu 神经机器翻译汉译乌研究
Pub Date : 2020-05-06 DOI: 10.32629/jai.v2i4.82

Machine Translation (MT) is used for giving a translation from a source language to a target language. Machine translation simply translates text or speech from one language to another language, but this process is not sufficient to give the perfect translation of a text due to the requirement of identification of whole expressions and their direct counterparts. Neural Machine Translation (NMT) is one of the most standard machine translation methods, which has made great progress in the recent years especially in non-universal languages. However, local language translation software for other foreign languages is limited and needs improving. In this paper, the Chinese language is translated to the Urdu language with the help of Open Neural Machine Translation (OpenNMT) in Deep Learning. Firstly, a Chineseto Urdu language sentences datasets were established and supported with Seven million sentences. After that, these datasets were trained by using the Open Neural Machine Translation (OpenNMT) method. At the final stage, the translation was compared to the desired translation with the help of the Bleu Score Method.
机器翻译(MT)用于提供从源语言到目标语言的翻译。机器翻译只是将文本或语音从一种语言翻译成另一种语言,但由于需要识别整个表达及其直接对应物,这一过程不足以实现文本的完美翻译。神经机器翻译(NMT)是最标准的机器翻译方法之一,近年来在非通用语言领域取得了很大的进展。然而,其他外语的本地语言翻译软件是有限的,需要改进。本文借助深度学习中的开放式神经机器翻译(OpenNMT),将汉语翻译成Urdu语言。首先,建立了汉语-乌尔都语句子数据集,并支持了700万个句子。然后,使用开放式神经机器翻译(OpenNMT)方法对这些数据集进行训练。在最后阶段,借助布鲁评分法将译文与期望的译文进行比较。

Brain-computer interface (BCI) is an emerging area of research that establishes a connection between the brain and external devices in a completely new way. It provides a new idea about the rehabilitation of brain diseases, human-computer interaction and augmented reality. One of the main problems of implementing BCI is to recognize and classify the motor imagery Electroencephalography(EEG) signals effectively. This paper takes the motor imagery feature data of EEG as the research object to conduct the research of multi-classification method. In this study, we use the Emotiv helmet with 16 biomedical sensors to obtain EEG signal, adopt the fast independent component analysis and the fast Fourier transform to realize signal preprocessing and select the common spatial pattern algorithm to extract the features of the motor imagery EEG signal. In order to improve the accuracy of recognition of EEG signal, a new deep learning network is designed for multi-channel self-acquired EEG data set which is named as min-VGG-LSTMnet in this paper. The network combines Long Short-Term Memory Network with convolutional neural network VGG and achieves the four-class task of the left-hand, right-hand, left-foot and right-foot lifting movements based on motor imagery. The results show that the accuracy of the proposed classification method is at least 8.18% higher than other mainstream deep learning methods.
脑机接口(BCI)是一个新兴的研究领域,它以一种全新的方式建立了大脑和外部设备之间的连接。它为脑疾病的康复、人机交互和增强现实提供了新的思路。实现脑机接口的主要问题之一是有效地识别和分类运动图像脑电图信号。本文以脑电运动图像特征数据为研究对象,进行多分类方法的研究。在本研究中,我们使用带有16个生物医学传感器的Emotiv头盔获取脑电信号,采用快速独立分量分析和快速傅立叶变换实现信号预处理,并选择通用的空间模式算法提取运动图像脑电信号的特征。为了提高脑电信号识别的准确性,本文针对多通道自采集脑电信号集设计了一种新的深度学习网络,命名为min-VGG-LSTMnet。该网络将长短期记忆网络与卷积神经网络VGG相结合,实现了基于运动意象的左、右、左、右脚举动作四类任务。结果表明,所提分类方法的准确率比其他主流深度学习方法至少提高8.18%。

Outdoor temperature estimation using ANFIS for soft sensors 使用ANFIS对软传感器进行室外温度估计
Pub Date : 2019-12-04 DOI: 10.32629/jai.v2i3.58
Zahra Pezeshki, S. M. Mazinani, E. Omidvar
In recent years, several studies using smart methods and soft computing in the field of HVAC systems has been provided. In this paper, we propose a framework which will strengthen the benefits of the fuzzy logic and neural fuzzy systems to estimate outdoor temperature. In this regard, ANFIS is used in effective combination of strategic information for estimating the outdoor temperature of the building. A novel versatile calculation focused around ANFIS is proposed to adjust logical progressions and to weaken the questionable aggravation of estimation information from multisensory. Due to ANFIS accuracy in specialized predictions, it is an effective device to manage vulnerabilities of each experiential framework. The neural fuzzy system can concentrate on measurable properties of the samples throughout the preparation sessions. Reproduction results demonstrate that the calculation can successfully alter the framework to adjust context oriented progressions and has solid combination capacity in opposing questionable data. This sagacious estimator is actualized utilizing Matlab and the exhibitions are explored. The aim of this study is to improve the overall performance of HVAC systems in terms of energy efficiency and thermal comfort in the building.
近年来,在暖通空调系统领域开展了一些应用智能方法和软计算的研究。在本文中,我们提出了一个框架,该框架将加强模糊逻辑和神经模糊系统在室外温度估计中的优势。在这方面,ANFIS被用于有效地组合战略信息来估计建筑物的室外温度。提出了一种新颖的基于ANFIS的通用计算方法,以调整逻辑进程并削弱多感官估计信息的可疑加重。由于ANFIS在专业预测中的准确性,它是管理每个经验框架漏洞的有效工具。神经模糊系统可以集中在整个制备过程中样品的可测量特性。再现结果表明,该算法可以成功地改变框架以调整面向上下文的进展,并且在反对可疑数据方面具有很强的组合能力。利用Matlab实现了该智能估计器,并对其性能进行了探讨。本研究的目的是在建筑的能源效率和热舒适方面提高暖通空调系统的整体性能。

Pub Date : 2019-12-03 DOI: 10.32629/jai.v2i3.57

Pedestrian detection is a critical challenge in the field of general object detection, the performance of object detection has advanced with the development of deep learning. However, considerable improvement is still required for pedestrian detection, considering the differences in pedestrian wears, action, and posture. In the driver assistance system, it is necessary to further improve the intelligent pedestrian detection ability. We present a method based on the combination of SSD and GAN to improve the performance of pedestrian detection. Firstly, we assess the impact of different kinds of methods which can detect pedestrians based on SSD and optimize the detection for pedestrian characteristics. Secondly, we propose a novel network architecture, namely data synthesis PS-GAN to generate diverse pedestrian data for verifying the effectiveness of massive training data to SSD detector. Experimental results show that the proposed manners can improve the performance of pedestrian detection to some extent. At last, we use the pedestrian detector to simulate a specific application of motor vehicle assisted driving which would make the detector focus on specific pedestrians according to the velocity of the vehicle. The results establish the validity of the approach.
行人检测是一般目标检测领域的一个关键挑战,随着深度学习的发展,目标检测的性能也在不断提高。然而,考虑到行人穿着、动作和姿势的差异,行人检测仍然需要相当大的改进。在驾驶员辅助系统中,有必要进一步提高智能行人检测能力。提出了一种基于SSD和GAN相结合的行人检测方法。首先,我们评估了基于SSD的各种行人检测方法的影响,并对行人特征的检测进行了优化。其次,我们提出了一种新的网络架构,即数据合成PS-GAN来生成多样化的行人数据,以验证海量训练数据对SSD检测器的有效性。实验结果表明,该方法能在一定程度上提高行人检测的性能。最后,我们使用行人检测器来模拟机动车辆辅助驾驶的具体应用,使检测器根据车辆的速度聚焦到特定的行人上。结果证明了该方法的有效性。

Firstly, we assess the impact of different kinds of methods which can detect pedestrians based on SSD and optimize the detection for pedestrian characteristics. Secondly, we propose a novel network architecture, namely data synthesis PS-GAN to generate diverse pedestrian data for verifying the effectiveness of massive training data to SSD detector. Experimental results show that the proposed manners can improve the performance of pedestrian detection to some extent. At last, we use the pedestrian detector to simulate a specific application of motor vehicle assisted driving which would make the detector focus on specific pedestrians according to the velocity of the vehicle. The results establish the validity of the approach.","PeriodicalId":70721,"journal":{"name":"自主智能(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41477706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a context of constant evolution of technologies for scientific, economic and social purposes, Artificial Intelligence (AI) and Internet of Things (IoT) have seen significant progress over the past few years. As much as Human-Machine interactions are needed and tasks automation is undeniable, it is important that electronic devices (computers, cars, sensors…) could also communicate with humans just as well as they communicate together. The emergence of automated training and neural networks marked the beginning of a new conversational capability for the machines, illustrated with chat-bots. Nonetheless, using this technology is not sufficient, as they often give inappropriate or unrelated answers, usually when the subject changes. To improve this technology, the problem of defining a communication language constructed from scratch is addressed, in the intention to give machines the possibility to create a new and adapted exchange channel between them. Equipping each machine with a sound emitting system which accompany each individual or collective goal accomplishment, the convergence toward a common ‘’language’’ is analyzed, exactly as it is supposed to have happened for humans in the past. By constraining the language to satisfy the two main human language properties of being ground-based and of compositionality, rapidly converging evolution of syntactic communication is obtained, opening the way of a meaningful language between machines.
在科学、经济和社会目的技术不断发展的背景下,人工智能(AI)和物联网(IoT)在过去几年中取得了重大进展。尽管需要人机交互,任务自动化是不可否认的,但重要的是,电子设备(计算机、汽车、传感器…)也可以像人类在一起通信一样与人类通信。自动训练和神经网络的出现标志着机器新的对话能力的开始,聊天机器人就是例证。尽管如此,使用这项技术是不够的,因为他们经常给出不恰当或无关的答案,通常是在主题发生变化时。为了改进这项技术,解决了定义从头开始构建的通信语言的问题,目的是让机器有可能在它们之间创建一个新的、经过调整的交换通道。为每台机器配备一个声音发射系统,伴随着每一个个人或集体的目标实现,分析了向共同“语言”的趋同,就像过去人类应该发生的那样。通过约束语言以满足人类语言的两个主要特性,即基础性和复合性,可以获得句法交际的快速趋同进化,为机器之间的有意义语言开辟道路。
