TRANSCRIPT

  • Kernelized Sorting (Poster ID: W48) Novi Quadrianto, Le Song, and Alex J. Smola Problem : Given two sets of observations X = {(xi)}mi=1 and Y = {(yi)}mi=1, sort yis according to xis without a cross domain comparison.

    Solution : Maximizing dependence by permuting yis π∗ = argmax

    π∈Π trace(HKHπLπ>) ; Kij = k(xi, xj), Lij = l(yi, yj)
