最大后验概率 meaning in Chinese
maximum a posteriori probability
Examples
- A new method of image de - noise based on wavelet packet and median filtering
基于马尔科夫约束最大后验概率三维显微图像复原算法 - The efficiency of this algorithm can be recognized from the experimental results which are attached at the end of this thesis . this thesis ends with the study of the maximum a posteriori ( map ) method with
本文最后对最大后验概率估计法进行了研究,给出了最大后验概率估计法的原理、方法和步骤。 - In this paper , we consider the concatenation of bose - chaudury - hocquenheim ( bch ) and repetition codes and present soft - decision decoding schemes based on a map ( maximum a posterior probability ) criterion
在本文中，我们考虑了bch码和重复码的级联编码，并且基于最大后验概率准则，提出了一种软判决解码方法。 - Then the paper brings forward map rule as recognition judgment criterion , and uses perception and bp nn to process image , it is very useful for preventing forest fire and alleviating harms to our society and country
最后提出最大后验概率( map )准则作为判决依据，借助感知器和bp神经元网络对图像予以识别，为防止森林火灾的发生、减轻森林火灾带来的危害奠定基础。 - Turbo codes represent the new code structures , which consist of pccc ( parallel serially convolutional code ) and sccc ( serially concatenated convolutional code ) . in this paper , the background of turbo codes are firstly introduced , which includes the base principle of error correction code 、 block code and convolutional code ; the principle of turbo code and the iterative decoding is secondly expanded ; the key decoding algorithm : a revised map algorithm and iterative decoding theory are detailed ; then , a new turbo code structure : hccc ( hybrid concatenated convolutional code ) is presented , and the capacity of this code method is analyzed , the average capacity upper bound is derived ; at last , this code is simulated on awgn ( additive white gaussian noise ) channel and rayleigh fading channel
