unit representation

Object-Attribute-Value ( OAV) knowledge representation, a knowledge representation method in knowledge projects, can be used to describe any knowledge unit or fact.

前言：“对象属性值三元组法”（简称OAV法）是知识工程中的一种知识表达方法，可用来描述任何一种知识单元或事实。

The investigation shows that the evaluation factors for the hidden layer of a feed-forward neural network are composed of the dimensions of representation space and target space, the number of hidden units, and the error compensation efficiency of each hidden unit.

结果表明：表示空间与目标空闽维数、隐单元数目以及每个隐单元的误差补偿效率决定了前馈神经网络隐层的评测因素。

In this paper, we give an explicit representation of the Sasaki metric on a vector bundle. In particular, we get Sasaki metric on unit tangent bundle T_1S~ ( 2n+ 1), by which we calculate the volume of the Hopf vector field V_h.
