数据编码 meaning in Chinese
coding of data
data code
data encoding
Examples
- Traditional coding algorithms are based on simple n - gram models . those distant constraints and some redundancies in natural language , such as word order redundancies , semantic redundancies and syntactic redundancies , are neglected in the n - gram models . in order to find and reduce those redundancies , we need more intelligent algorithms based on more effective models
通用无损数据编码是数据压缩领域的一个重要的分支，现有的无损数据编码方法大多是基于n - gram模型的， n - gram模型忽略了自然语言中的远距离约束和诸如词序冗余、语义冗余、句法冗余等冗余，为了找出并减少这些冗余，需要更有效的语言模型和更智能的算法。 - Neural networks are used more frequently in lossy data coding than in general lossless data coding , because standard neural networks must be trained off - line and they are too slow to be practical . in this thesis , statistical language model based on maximum entropy and neural networks are discussed particularly . then , an arithmetic coding algorithm based on maximum entropy and neural networks are proposed in this thesis
传统的人工神经网络数据编码算法需要离线训练且编码速度慢，因此通常多用于专用有损编码领域如声音、图像编码等，在无损数据编码领域应用较少，针对这种现状，本文详细地研究了最大熵统计语言模型和神经网络算法各自的特点，在此基础上提出了一种基于神经网络和最大熵原理的算术编码方法，这是一种自适应的可在线学习的算法，并具有精简的网络结构。 - The jpeg compression algorithm takes one kind of highly effective static state image data compression algorithm . the widespread application of jpeg in multitudinous inserted in the type multimedia product the image data code and the decoding speed has already become a most important aspect which the restriction product performance enhanced
