查询词典 features

The conditional nature of the distribution over label sequence can depend on non-independent, interacting features of the observation sequence. CRFs offer a solution to the problems in Chinese shallow parsing with hidden Markov models or with maximum entropy Markov models. First, as HMMs are generative, it is hard to employ overlapping features and nonindependent features of the inputs such as surrounding words.

According to the analysis of features of the key outcrop sequence stratigraphy, build the sequence frame, through the section comparison, and the study of feature of the 5 key outcrops, then it can be concluded that, conglomerate on the denudation plane or the other contrastive sediment are the main features surrounding the bottom border of the sequence. In the foreland basin sediment environment, the transilient group of mud rock and sandstone are the main sediment features of low-stand system tract. Thick mud rock and sandstone interbedded is the chief component of transgressive system tract, sometimes together with thick turbidity current sandstone; High-stand system tract is composed by the combination of mud rock and sandstone interbedded, with the progradation as its main style. Maximum flooding surface Sediment are usually mudstone, and the thickness is different from each other.

As feature extraction acts an important role in pattern recognition system, we propose three novel feature extraction methods for HCCR: a、Two structural feature extraction methods, Stroke Cross Counting Features and Peripheral Features are studied. According to the characteristics of Chinese handwriting samples, we extend the SCCF and PF respectively to weighted elastic SCCF and weighted elastic PF. Experiments show that the modified feature extraction approaches are better than original approaches. b、A new statistical feature extraction method——Elastic Meshing Directional Decomposition Feature extraction is proposed. According to the stroke statistical properties of Chinese character, we first decompose a handwritten character pattern into four directional subpatterns. Then a set of elastic meshes are applied to each of the four subpatterns respectively to extract the pixel distribution features.

统计识别方法：利用统计模式识别的经典方法——Bayes分类方法来进行汉字识别的研究，特征提取是统计模式识别的关键，本文着重围绕手写体汉字的特征分析和提取方法进行了研究，提出了三种特征提取的新方法： a、两种改进的结构特征提取方法：在笔划密度特征和外围特征的基础上，结合手写体汉字的特点，提出了加权非均匀笔划密度特征、加权非均匀外围特征的特征提取新方案； b、一种新的统计特征提取方法——弹性网格方向分解特征，根据汉字方块字的特点及笔划分布的统计特征，对手写体汉字进行横竖撇捺四方向的分解，并利用一系列的弹性网格对汉字分解后各分量的象素进行统计而提取特征，实验证明该特征提取方法用来进行手写体汉字识别是十分可行和有效的。
