One of them is diffusion geometry. A good demonstration of its power can be found in Stephane Lafon's web page. In this demonstration, one discovers that the suite of images on the left can be put in order following one parameter (rotation angle). So the big question is, how many dimensions would enable the classification of a smile ?
