cs229.stanford.eduA vector-valued random variable x ∈ Rn is said to have a multivariate normal (or Gaus-sian) distribution with mean µ ∈ Rnn ++ 1 if its probability density function is given by p(x;µ,Σ) = 1 (2π)n/2|Σ|1/2 exp − 1 2 (x−µ)TΣ−1(x−µ) . 2 Gaussian facts Multivariate Gaussians turn out to be extremely handy in practice due to the ...
An Intuitive Tutorial to Gaussian Processes Regression
arxiv.orgGaus-sian processes model is a supervised learning method developed by computer sci-ence and statistics communities. Researchers with engineering backgrounds often find it is difficult to gain a clear understanding of it. To understand GPR, even only the basics needs to have knowledge of multivariate normal distribution, kernels,
6 Probability Density Functions (PDFs)
www.cs.toronto.eduThe exponent of the Gaus-sian is quadratic, and so its shape is essentially elliptical. Through diagonalization we find the major axes of the ellipse, and the variance of the distribution along those axes. Seeing the Gaus-sian this way often makes it easier to interpret the distribution.
Recti er Nonlinearities Improve Neural Network Acoustic Models
ai.stanford.edumodels perform substantially better than the Gaus-sian mixture models (GMMs) typically used in large vocabulary continuous speech recognition (LVCSR). DNN acoustic models were initially thought to perform well because of unsupervised pretraining (Dahl et al., 2011). However, DNNs with random initialization

Later on, many other machine-learning based methods of image denoising have appeared [2, 15, 38, 42, 43]. Demosaicing. To reduce manufacturing costs, most dig-ital camera sensors capture only one color (red, green and 3508
