semantic space meaning in English
语义空间
Examples
- Lsi comes from the field of information retrieval . it transforms the original vector space to abstract k - dimension semantic space . so the huge dimensions of the original vector space are reduced greatly , also the training speed and system performance are improved
系统中引入了信息检索中的常用技术? ?潜在语义索引，把原始向量空间转换到抽象的k维语义空间，实现原始向量空间的降维，提高网络训练速度和性能。 - It includes 3d semantic space and constraining based problem - solving method . the 3d semantic space is built to represent the relationship between the describing semantic word and product color . then , the product color schemes with related abstract sense words is achieved and saved in database
首先采用定性和定量相结合的方法，比较各抽象语义词汇对人心理感觉影响的差异，建立了抽象语言和色彩关联的三维风格语义空间，为色彩信息的表示及推理奠定了基础。 - The document space is generally of high dimensionality and clustering in such a high dimensional space is often infeasible due to the curse of dimensionality . so the primary step in document clustering is to project the document into a lower - rank semantic space in which the documents related to the same semantics are close to each other
基于文本空间的文本聚类因为其具有高维的特征而不容易直接实现,所以文本聚类的首要步骤就是将文本空间的数据投影到较低维的语义空间里,使在文本空间里相邻的数据向量在语义空间里根据某些提取的特征参数而相似。
