probability distribution density function

Figure 1 shows a typical normal probability density function, so called because most observations fall into this sort of distribution.

图1显示了一个典型的正态概率分布函数，这样命名是因为绝大多数值都属于这个分布范围内。

The method not only would be effective to describe the inter-frame correlation information, but overcome tie of the state probability density function being mixture Gauss distribution.

它不仅能有效地在语音识别中引入帧间相关信息，而且能克服状态输出概率密度函数为混合高斯分布的束缚。

The continuous ion exchange process was analysed through the concept of probability density and conversion distribution function.

引用概率密度的概念，即转化率分布密度函数对连续离子交换过程进行分析。
