Hello Mike. Nic to see you again. DT
Edwin Dalmaijer
Does this* mean that that the relative constellation of faces in multi-dimensional space is relatively unchanged, and thus that all faces aged in a similar (limited) set of ways? (*referring to finding that PCA+LDA works on aged photos too, while only PCA did not)
Colin Davis
Are the components in the PCA interpretable?
Edwin Dalmaijer
@Colin: This might be interesting reading (but wouldn't recommend it to be night reading): https://en.wikipedia.org/wiki/Eigenface
Chris Benton
Is your PCA applied directly to the pixels, or are you doing some image pre-processing beforehand?
