operating system Windows 7 matplotlib version : 1.1.0 obtained from sourceforge
the class seems to generate the same Wt matrix for every input. The every element of the weight matrix is either +sqrt(1/2) or -sqrt(1/2). dat1 = 4*np.random.randn(200,1) + 2 dat2 = dat1*.25 + 1*np.random.randn(200,1) pcaObj1 = PCA(np.hstack((dat1,dat2))) print pcaObj1.Wt dat3 = 2*np.random.randn(200,1) + 2 dat4 = dat3*2 + 3*np.random.randn(200,1) pcaObj2 = PCA(np.hstack((dat1,dat2))) print pcaObj2.Wt The output Y seems to be correct, and the projection function works. only the Wt matrix seems to be messed up. Am I using this class incorrectly, or could this be a bug? thanks, Justin ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
