查询词典 extrinsic feature

A feature extraction method is designed for linear predict vocoders widely used in the communication field. In this method, feature vectors are extracted not from the decoded waveform, but from the bit stream of transmission directly. Specifically for Wideband Adaptive Multi Rate vocoder, we implemented a text-independent speaker verification system.

A new study idea that makes the occupant injury prevention research and CAD/CAE technology on an integrate mathematical model by means of feature theories and feature design technologies was brought, and it is maybe useful if we study automobile passive safety on a new view of point.The conclusions of this thesis included that what are the main factors of airbag-related injuries and the preventive measures, based on the research of the relationships between injury parameters, such as HIC, chest acceleration, neck force, neck moment, femur axial force etc, and impact speed, belt-use, occupant size (50th and 5th), sitting position and so on. The thesis evaluated whether the effectiveness of the airbag can be increased by making the airbag adaptive to the crash conditions, and points out that the size of the ventilation hole has the dominating influence on the performance of the airbag and is a key factor for intelligent airbag, multi-stage and lower-power inflator can cost effectively minimize the risk of injury to occupants from crashes. It is important for the researchers of intelligent airbag to keep the small size unbelted occupants in focus and it is necessary to study deeply the influence of airbag fold patterns and the extremity out-of-position situation. These topics are important in the study of occupant injury prevention and vehicle safety design.

Firstly syntax parsing tools are used to extract context feature of terms, and natural language feature and statistical mutual information measure are integrated to compute relevancy degree of terms,then dynamic role and sememe are used as key to seek the relationship in HowNet semantic relationship framework, and explicit semantic lable is designated to the relationship.

首先通过句法分析提取术语的上下文特征，结合自然语言特征和互信息的方法计算术语之间的相关度，然后使用术语的义原和动态角色作为关键词，在知网语义关系框架中定位关系，并为关系指定明确的语义标签。

First, the character clustering algorithm regards the character as our features and then it can cluster these sentences of our target words to the correct group without any other resources. The average precision is 66.1%. Second, in the concept clustering algorithm of the aggregate computing, we use HowNet as the knowledge base of our feature words and obtain the concepts of these words. We cluster the sentences which have the same or similar concepts of the feature words into the same group. And then we can complement some lacks of the character clustering algorithm. The average precision is 72.3%. Third, regarding the concept clustering algorithm of the sememe distance, we use the sememe distance to compute its concept similarity. It improved similarity measure of the concept clustering algorithm of the aggregate computing. It achieves 81% average precision and gets better cluster quality.
