传统的基于包统计特征的机器学习方法适用于稳定的网络环境,当网络拥塞出现严重的时延和丢包时将产生较大误差。 |
The traditional machine learning methods based on statistical characteristics of packets work well in stable network environment, but not in congestion environment with serious delay and packet loss. |

因而本文提出基于粒计算模型的分类方法。 |
Therefore, a novel classification method based on granular computing is proposed in this paper. |

粒计算属于人工智能计算的分支,当数据缺失、信息不完全或是有噪数据仍拥有较高的分辨能力。 |
Granular computing belongs to the field of artificial intelligence computing, which is usually used to process missing, incomplete or noisy data. |

为此本文将网络流量定义成粒子并构造粒子间关系,再建立粒关系矩阵。 |
So we first define granules for the traffic, then construct the relations between the granules, and finally establish the relation matrix. |

传统的包统计特征只是粒关系矩阵当观测角度达到最大时的特例,因此粒关系矩阵对流量特性的描述更为全面,以此进行分类也更为精准。 |
The traditional statistical characteristics are only the special case of the relation matrix when the scale is the largest. The granular relation matrix can describe the traffic more comprehensively and classify them more accurately. |

最后实验数据证明了该方法的有效性和优越性。 |
The experiment results show its validity and advantages when compared with other methods. |

针对传统一致性判决方法主要对整句(段)话进行分析,并无对分析内容加以筛选,存在字典规模过大、计算复杂度高及结果易受静音等弱关联片段影响等不足,本文以唇型变化显著的韵母为代表性发音事件,结合音唇初始时延分布范围的统计结果,提出基于韵母发音事件匹配与位置时延分析的一致性判决方法。 |
For the mainstream lip motion and voice coherence judgment method, the whole sentence (segment) is analyzed without screening the content. This leads to large dictionary size and high computational complexity, and the result is vulnerable to weak related segments such as mute. Considering the vowel with significant lip shape changes as a representative pronunciation event and combining with the statistical results of the audio-visual initial delay distribution range, a consistent decision method based on audio-visual matching of vowel pronunciation events and position delay analysis is proposed. |

先利用提出的音视频结合韵母切分法对字典学习数据进行韵母段筛选,再通过学习所得的韵母字典分析韵母事件的音唇匹配度,并对各韵母出现位置的时延分布进行统计评分。 |
Firstly, the dictionary learning data is selected by the proposed audio-visual vowel segmentation method, and then the vowel dictionary is used to analyze the matching of the vowel event, and the time delay distribution of each vowel position is statistically scored. |

最后由韵母发音事件音唇匹配度得分与位置时延分析评分相融合的评分机制判决一致性。 |
A consistency judgment is made by a scoring mechanism in which the vowel pronunciation event lip matching score and the position delay analysis score are combined. |
