查询词典 probability density function

In the monitoring, the observed behaviour of process is analyzed to infer the probability that Markov chain model of normal profile supports the observed behaviour. A low probability of support indicates a anomalous process behavior that may result from intrusive activities.

监视过程中，根据马尔可夫模型对所观察到的进程行为的分析和概率推断来判定其行为是否偏离正常的行为轮廓，较低的概率意味者该行为是由入侵活动所引起的异常行为。

Aim To discuss and analyze the formation of normal probability curve and the features of De Moivre's probability thought.

The Generalized Kolmogorov Probability generalized the 1st Kolmogorov's axiom and allows the probability values to be within the whole open real interval of (-infinite,+infinite).

广义的柯尔莫果洛夫概率(Generalized Kolmogorov Probability)推广了柯尔莫果洛夫概率三公理的第一公理：概率可在开区间范围内取值。

No additional data for frequency tracking are need, but higher estimation accuracy and low computational complexity can be obtained. Finally, a kind of optimizing joint algorithm for symbol timing, frequency synchronization and channel estimation is proposed. The false alarm probability and miss detect probability of the symbol timing are derived. We proved that the time－frequency offset domain random sequence sliding in the frequency offset direction is orthogonal with the original random sequence, and proposed a new integer frequency offset estimation algorithm. The coarse estimation methods for fractional frequency offset both in AWGN and multipath channels are proposed too.

最后，提出了一种优化的符号同步、频偏估计和信道估计的联合算法，推导了符号同步方法的虚警概率和漏检概率，给出了随机序列在时间－频率偏移域沿频率偏移方向滑动后与原序列近似正交的证明，提出了一种新的在时间－频率偏移域沿频率偏移方向进行滑动相关估计整数频偏的方法，提出了在AWGN信道和多径信道下进行小数频偏粗估计的方法，给出了小数频偏细估计的ML估计结果和利用频域PN序列取值特性的简洁的信道估计结果。

In the process of recognition, the prior probability is supposed to be the same, the posterior probability is calculated according to GMM, and then the instrument class is determined.

乐器识别在科学研究和实际应用中有重要意义。目前人们对于音频有不同的认识，还没有一种成熟的理论用于研究人类如何识别声源。

Finally, the impact of loading on the probability of occurring of cascading failures is studied, and a phenomenon that power systems with more uniform loading have lower probability of occurring of cascading failures is found.

分析了负载情况对系统发生连锁故障概率的影响，发现系统负载较均匀时发生连锁故障的概率将大大降低。

On the other hand, in terms of the above,"superposition principle of probability amplitudes" in quantum mechanics ought to be indicated as "probability amplitudes is independent of passage conditions."

另一方面，按照上面的用语，量子力学中的"概率幅的迭加原理"应表成"概率幅不依赖于通道条件"。

Most arithmetics of data fusion have its default in the processing to uncertain and unintegrity data. The method of probability and statistics is difficult to obtain the prior probability of the occurrence.

数据融合的方法很多，但现有算法都有各自的优缺点，因而也都有各自的适用范围，到目前为止尚未形成统一的算法理论。

While investigating the verdicts by balance of probability in civil procedure and their theoretical basis, it introduces verdicts by the flexible standard and prior probability approach and their theoretical basis.

前苏联著名的概率学家Kolmogorov曾说过："概率论的价值只有通过极限定理才能被揭示，没有极限定理就不可能去理解概率论中的基本概念的真正含义。"
