In this paper , an adaptive hidden markov model ( ahmm ) approach for on - line hand - drawn shape recognition is presented . in our method , hmms are chosen as the core recognizer due to its great ability to model stochastic time series . many improvements are made to the traditional hmm recognizer in order to increase the flexibility of the recognition system , the resulting framework can not only adaptively learn from training data , but also can adapt system behavior to input hand - drawn shape 本文提出了一种用于联机手绘图形的自适应隐马尔科夫模型识别方法,该方法利用隐马尔可夫模型( hmm )对时序随机序列的描述能力作为手绘图形识别中的核心分类器,并且在传统hmm识别结构的基础上进行了改进,使得识别系统不仅具有自适应学习训练样本的能力,而且具有根据输入图形特征调节系统行为的能力。
Meanwhile , a major problem in anomaly detection is that system can issue false alarms when there are modifications in the normal system behavior ; therefore , we present an adaptive data - mining framework for anomaly detection . the normal profile can be updated at regular intervals , and as a result , false alarms are significantly reduced 同时,在异常检测系统中,当用户或系统行为的正常轮廓发生变化时,由于检测所需的规则库不能及时的更新,容易造成将用户或系统的正常行为误报为入侵的情况,因此,文中介绍了一个构造自适应系统的方法,通过这种方法,规则库可以自动的更新,并可以有效的减少误报。
Servo - control technology is one of the most important part of mechtronics . which is widely used on the automatic equipments . such as cnc and industrial robot . as the scale of production becomes larger and larger . the demand and requirements becomes higher and higher . ac servo system has advantage over dc servo system . so study on improving the ac servo system behavior has important sense 随着现代化生产规模的不断扩大,各个行业对电伺服系统的需求愈益增大,并对其性能提出了更高的要求。由于交流伺服系统具有直流系统不可比拟的优越性,因此,研究并制造高性能、高可靠性的交流伺服控制系统有着十分重要的现实意义。
Contrasting this , in feedback control the most majority of complex systems are controlled using sampled observations of system behavior taken at discrete time instants . thus the resulting controlled systems are hybrid systems , which are called sampled - data systems , involving both continuous - time and discrete - time signals . the investigation of sampled - data systems is motivated primarily due to the widespread use of digitally implemented controller in present - day feedback control of continuous - time systems 工程实践中遇到的动态系统通常是连续时间系统,与此相反,大多数复杂系统的反馈控制却是通过观察采样点上的系统行为来进行控制的,结果所得到的反馈控制系统是个混合系统,它含有连续信号和离散信号,这样的系统称之为采样系统,当今连续受控系统中数字控制器的广泛运用促进了对采样系统的研究,已有的线性采样系统理论显然不能满足处理非线性采样系统的需要,因此近年来非线性采样系统的分析与设计已经成为国际控制论界的持续的研究热点之一。
