Dear author,
thank you for your exciting work.
I cannot understand the meaning and the function of the operator ⊗ in eq (4) of your paper https://openreview.net/pdf?id=Sk_P2Q9sG&source=post_page
Could you please clarify it for me?
Thanks
Hi Francesco! As described below the Equation (2), v ⊗2 means that v v^T. So, if you have a d-dimensional vector, then d ⊗2 will be a d by d matrix whose (i,j)-th element is v_j * v_j.
