  遵循随机时间序列模型的股价预报研究
• According to the data of the covariance - stationary stochastic time series , we can get the state space modeling algorithm quickly and stably by singular value decompositi on and orthogonal projection . this algorithm will be faster and more stable
  在已知平稳随机时间序列样本数据的情况下，论述了如何采用正交投影算法和正交奇异值算法建立随机时间序列的状态空间模型和状态矢量估计，这种数学建模方法对于船舶机舱中的系统数学建模有很大的帮助
• 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。
