  • multiple kernel learning presentation 思路

    Overall introduction of the topic, the keywords, the references.

    Part 1: Introduction on svm(5 min)

      first show that svm is what kind of a classifier. via graphs and examples. The notion of support vectors . the use of support vectors.

      svm characteristic:largest margin,geometric margin and function margin, induction,finally reduced to a QP problem.

      svm applications

    Part 2: kernel method and kernel matrix (5 min)

      why kernel method

      what's kernel method for 

      the notion of kernel functions.

      the notion of similarity function

      inner product

      example

    Part 3: the SMO algorithm

    Part 4:  muliple kernel learning(20 min)

      why MLK-------the need for flexibility to combine different kernel matrix linearly.

      what MLK yields and where the problem lies

      the formulation of MLK problem

      the notion of SKM and the induction of it.   Primal problem --> Dual problem-->KKT-->some conclusions 

      kernelization-->the kernelized problem formulation

      Equavalence of the two formulation

      why we can't solve it

      regularize SKM: the dual problem -->solving the MY-regularized problem using SMO

    Conclusion

      propose a novel dual formulation to apply SMO to MY-regularized non-smooth convex problem.

      and the author's simulation show that the SMO will be faster than the normal Mosek
