  2. 1 I II Which projection in the figure above belongs to LDA and which one belongs to PCA: A) I=PCA and II=LDA B) I=LDA and II=PCA

  3. 2 • Consider Kernel Fisher Discriminant Analysis with the kernel . • Claim: We can generate nonlinear projects of the data with this method • (linear projection = orthogonal projection on a hyperplane). • True • False

  4. 3 • In Canonical Correlation Analysis we need two datasets: • {Xan|a=1..A,n=1..N} and {Zbm|b=1..B,m=1..M}. Foor CCA to work need: • A=B and M=N • A=B but not necessarily M=N • M=N but not necessarily A=B • Neither A=B nor M=N are necessary

  5. 4 • Minimizing the following objective would generate useful projections w’x and v’y that would be highly correlated. • True • False
