在本文中我们将以高斯过程回归(Gaussian process regression,GPR)模型为例,对MOGP最基础的几个模型,即Intrinsic coregionalization model (ICM)、Semiparametric Latent Factor Model(SLFM)和Linear model of coregionalization(LMC)分别进行介绍。 注:本文内容主要参考Alvarez MA et al.的综述文章[1]及其slides[2]。
In this paper, a multi-fidelity multi-output Gaussian process (MMGP) model is proposed to deal with multi-fidelity (MF) data with multiple correlated outputs. It aims to approximate multiple correlated high-fidelity (HF) functions enhanced by the low-fidelity (LF) data. The MMGP model can ...
相比于单输出的高斯过程回归问题,多输出高斯过程(multiple output GP,MOGP)的回归的复杂性体现在训练集和测试集的输出为一个向量。经典的GPR问题存在以下结论: 令随机向量X=[x1,x2,⋯xn]服从服从多元高斯分布X∼N(μ,Σ),其中:X1=[x1,...,xm]为已观测变量,X2=[xm+1,...,xn]为未知变量,则: X=...
Multi-output Gaussian process using a Gaussian kernel and a Gaussian covariance function This example shows how it is possible to make multiple regression over four outputs using a Gaussian process constructed with the convolution process approach. Note that there are some ranges of missing data for...
The computation in convolution layers has five levels of parallelism: synaptic parallelism, neuron parallelism, input feature map parallelism, output feature map parallelism, and batch processing parallelism. These five parallelization methods make up the whole convolution process. The levels are sorted fro...
The fading number of memoryless multiple-input multiple-output fading channels In this correspondence, we derive the fading number of multiple-input multiple-output (MIMO) flat-fading channels of general (not necessarily Gaussian) reg... SM Moser - 《IEEE Transactions on Information Theory》 被引量...
The output of the benchmark function 5 (BF5) waving uniformly within the region. The benchmark function 6 (BF6) has a Gaussian function located in the center and another Gaussian function with some periodic terms. Therefore, it produces a single peak region and a boundary region where the ...
A method for wireless encoding includes encoding wireless multiple input and multiple output signals in accordance with a codebook being one of a discrete codebook restricting elements of codebook ent
