function [X, t] = linRnd(d, n)
|
|
% Generate data from a linear model p(t|w,x)=G(w'x+w0,sigma), sigma=sqrt(1/beta)
|
|
% where w and w0 are generated from Gauss(0,1), beta is generated from
|
|
% Gamma(1,1), X is generated form [0,1].
|
|
% Input:
|
|
% d: dimension of data
|
|
% n: number of data
|
|
% Output:
|
|
% X: d x n data matrix
|
|
% t: 1 x n response variable
