Confusion about your SDA implement
Hi, I'm reading SDA paper. http://www.bmva.org/bmvc/2015/papers/paper024/paper024.pdf
And I find your great work,but I'm a little confused about some lines of your code.
var_ratio = np.diag(np.multiply( np.power(pe_S,-0.5), np.power(pe_T,0.5) ))
Ms = np.dot( np.dot( np.dot(pc_S.T,pc_S) ,pc_T.T) , var_ratio )
Mt = pc_T.T
newS = np.dot(Xs , Ms)
newT = np.dot(Xt , Mt)
I think the target domain can't not be modified.
