Gaussian Splatting 使用了高斯椭球作为基本渲染元素。 我知道一个高斯椭球主要有均值和协方差两个参数,但是这两个参数怎么能够表达三维空间中的任意一个高斯椭球? 三维空间中的任意一个高斯椭球可以由一个归一化高斯球经过拉伸,旋转和平移得到。 平移可以直接由高斯椭球的均值表达。
Maximum likelihood estimation for the covariance R of a zero-mean Gaussian process is considered, with no assumptions on the covariance or the time parameter set T. It is shown that the likelihood function is a.s. unbounded in general, and a sieve estimator R is constructed. The distribution...

where D is the diffusion matrix that describes the covariance of a Gaussian white noise that acts on z. The initial condition of this Fokker-Planck equation is set to be p(z, t) = δ(0) and the boundary condition is p(±∞, t) = 0. The solution of this linear system is...
samples in the presence of a fraction of malicious noise. This is in contrast to much recent work where the noise itself is assumed to be from a distribution of known type. The agnostic problem includes many interesting special cases, e.g., learning the parameters of a single Gaussian (or...
One of the most important examples of a continuous joint distribution is the bivariate Gaussian distribution. Let’s begin with understanding what it looks like when we combine two indepdendent Gaussian random variables X ∼ N(µ x ,σ x ) and Y ∼ N(µ y ,σ y ). Because of ...
The bispectrum is the lowest-order statistic providing an estimate for non-Gaussianities of a distribution, and the bispectrum covariance depicts the errors of the bispectrum measurement and their correlation on different scales. Currently, there do exist fitting formulae for the bispectrum and an ...
