about the conclusion

[eyuansu62]

hi, i feel confused about the conclusion.
You said you propose a positive definite TSW, and then your said it is also negative definite.
So it is positive and negative definite at the same time? (i am not subjected in math so i feel some confused)

You may confuse about the kernel & distance with the same TSW name. While the TSW kernel is p.d., the TSW distance is n.d.
