查询词典 a posteriori

Because a posteriori filter can generally get lower variance bound than a priori one, a posteriori filtering method is also given, which is unbiased to the nominal system of the interval one under consideration.

Study is made of Bayes estimation of the error rate proportionality parameter θ in the JM model for testing software reliability,leading to the a priori,a posteriori distribution of θ and the coresponding Bayes estimates on the Bayes assumption,Jeffrey s principle and conjugate dis- tribution,together with their comparison and discussion.

讨论了软件可靠性模型——JM 模型中故障率比例参数θ的 Bayes 估计问题，分别求出了在贝叶斯假设、杰弗莱原则和共轭分布原则下参数θ的先验分布、后验分布及相应的 Bayes 估计，并对它们进行了比较和讨论。

In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.

在该算法中，期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量，由阵列接收信号计算出各候选波达方向的后验概率，并将后验概率的分布作为是否需要进行二次采样的判断标准；随后，对各波达方向上的波束成形权值线性加权，便可得到自适应波束成形器，权系数为各候选波达方向的后验概率值。

It employs a shrink training algorithm base on the deterministic annealing global optimization technique. This training algorithm adopts a maximum a posteriori optimization criterion.

它采用了一种基于确定性退火全局优化技术的收缩训练算法，这种算法以最大后验概率为优化标准。

In this paper, a new region-determined half tree hierarchical MRF model is proposed and its region-determined maximizer of the posteriori marginals algorithm is inferred.

本文提出一种新的基于区域确定的半树分层 MRF 算法，并推导出它的最大后验边缘概率(Maximizer of the posteriori marginal， MPM)算法。

There is a gap between what we can in principle be given in perception and any belief about the past. And because in principle we could never be given anything about the past directly, the gap is one that no justified a posteriori inference could bridge. For anything to which we could appeal in support of a hypothesis about the connection between the past and present will simply give us more information about the present. Thus, unless our conception of the past is a form of idealism analogous to phenomenalism regarding the external world, skepticism follows.

在'原则上我们在感知中被给予的'和'任何关于过去的信念'之间有一个gap，又因为在原则上我们不能被直接给予过去的东西，这个gap就没有一个后天『a posteriori』inference能架桥辩护，因为任何可诉诸以支持关于过去和当前的关联的假说的东西，也不过是给我们更多关于当前的信息，如此，除非我们对过去的概念是类似关于外在世界的现象论的这种观念论的一个形式，否则怀疑论就会得到。

This paper presents a novel multiple object segmentation algorithm based on a Bayesian framework. According to the characteristic of the intra-frame and inter-frame information, a representation of Maximization of the A posteriori Probability of spatio-temporal label field is proposed. So a minimization of energy function is obtained.

摘要该文提出了一种基于贝叶斯框架的时空标记场最大后验概率的多视频对象分割算法，根据视频序列帧间和帧内信息的不同特点，建立基于多个对象分割标记场的最大后验概率公式，并导出其最小能量函数，通过求解最小能量使其分割标记的后验概率达到最大。

This difference, it should be observed, applies only to the question of proving God's actual existence; for, His self-existence being admitted, it is necessary to employ a priori or deductive inference in order to arrive at a knowledge of His nature and attributes, and as it is impossible to develop the arguments for His existence without some working notion of His nature, it is necessary to some extent to anticipate the deductive stage and combine the a priori with the a posteriori method.

这种差异，应该得到遵守，只适用於该问题的证明上帝的实际存在，他的自我存在，被承认，有必要聘请一名或先验演绎推理，以得出一个认识他的本质和属性，因为这是不可能发展的论点，他的存在，如果没有某种工作的概念，其本质，是要在一定程度上预测演绎阶段结合起来，把先验与后验方法。

First of all, this paper introduces a general method of designing a BMS of which pricing consists of a prior premium and a posteriori premium.

本文首先介绍了奖惩系统设计的一般方法，这包括先验保费和后验保费的费率厘定问题。

Such knowledge is entitled a priori , and distinguished from the [43] empirical , which has its sources a posteriori , that is, in experience.

满足这种性质的知识可以称为 priori&先验的&，以区别于&经验的&。&经验的&知识从&posteriori&来，即是从经验中来。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
