Abstract arXiv:1607.06450v1 [stat.ML] 21 Jul 2016
arxiv.orgGeoffrey E. Hinton University of Toronto and Google Inc. hinton@cs.toronto.edu Abstract Training state-of-the-art, deep neural networks is computationally expensive. One way to reduce the training time is to normalize the activities of the neurons. A recently introduced technique called batch normalization uses the distribution of
Logistic Regression - Pennsylvania State University
personal.psu.eduLogistic Regression I The Newton-Raphson step is βnew = βold +(XTWX)−1XT(y −p) = (XTWX)−1XTW(Xβold +W−1(y −p)) = (XTWX)−1XTWz , where z , Xβold +W−1(y −p). I If z is viewed as a response and X is the input matrix, βnew is the solution to a weighted least square problem: βnew ←argmin β (z−Xβ)TW(z−Xβ) . I Recall that linear regression by least square is …
Importance Sampling - U-M LSA
dept.stat.lsa.umich.eduE(X) where you can’t even generate from the distribution of X, importance sampling is necessary. The final, and most crucial, situation where importance sampling is useful is when you want to generate from a density you only know up to a multiplicative constant.

Posterior Predictive Distribution - University of South ...
people.stat.sc.eduPosterior Predictive Distribution I Recall that for a fixed value of θ, our data X follow the distribution p(X|θ). I However, the true value of θ is uncertain, so we should average over the possible values of θ to get a better idea of the distribution of X. I Before taking the sample, the uncertainty in θ is represented by the prior distribution p(θ).
Post Hoc Power: Tables and Commentary - University of Iowa
stat.uiowa.eduThere is substantial literature, much of it outside of the social sciences (e.g., Goodman and Berlin, 1994; Zumbo and Hubley, 1998; Levine and Ensom, 2001; Hoenig and Heisey, 2001), that takes an opposing view to PHP practices. Lenth (2001) points out that PHP is simply a function of the P value of the test, and thus adds no new information.
