Sorted by: 9. Say that mat1 is n × d and mat2 is m × d. Recall that the Gaussian RBF kernel is defined as k ( x, y) = exp ( − 1 2 σ 2 ‖ x − y ‖ 2) . But we can write ‖ x − y ‖ 2 as ( x − y) T ( x − y) = x T x + y T y − 2 x T y. The code uses this decomposition. First, the trnorms1 vector stores x T x for each ...
