- The particle filter can resolve a problem on nonlinear and non - gaussian model , and has been applied successfully in many fields
它可以处理模型方程为非线性、噪声分布为非高斯分布的问题,在许多领域得到了成功的应用。 - On the assumption that imagery pixel follows non - normal distribution in high resolution imaging , a new method of phase errors estimation based on higher - order statistics is proposed for sar imagery autofocusing
在高分辨成像情况下，基于图像像素强度服从非高斯分布的假设，提出了一种基于三阶累积量的自聚焦方法。 - Although the above two methods own pretty good filtering performance when system noise and observation noise are non - gaussian , their filtering performance will descend or even diverge when non - gaussian distribution occurs
上述两种方法在当系统噪声和观测噪声满足高斯分布特性的时候具有较好的滤波性能,而对于非高斯分布噪声上述滤波方法的指标下降,甚至出现发散。 - Based on unsupervised learning , sparse coding is suitable to describe images with non - gaussian distribution and can get rid of the high order redundancy among the image pixels . since the basis function of sparse coding has build - in clustering property , it increases the inter - class variations of the features
稀疏编码是一种基于非监督学习的算法，它适合描述具有非高斯分布的数据对象，能够有效地消除图像象素点之间的冗余，并具有内在的聚类特性。 - The different galactic gravitational potential have not clear influence upon the perigalactic distance , eccentricity and uncertainty of orbital parameters , but which is significant for other parameters , such as the apogalactic distance , semi - major axis , radial period and azimuth period and so on ; ( 5 ) the monte carlo simulation show that : the distribution morphologies of the orbital parameters which are produced by simulation data are separated into three types : gaussian profile , semi - gaussian profile and non - gaussian profile
不同的引力势模型对近银心距、偏心率和参数的不确定度等量影响较小，但是对远银心距、轨道半长轴、径向周期和方位周期等参数影响较为明显。 ( 5 ) montecarlo模拟的结果表明：根据模拟观测数据得到的轨道参数的分布形态大致可分为三类：高斯分布、准高斯分布和非高斯分布；观测数据对轨道参数的影响与样本的选取、轨道参数的类型等有关。
