Problem
I am now working on a relatively new field in machine learning. My advisor suggested me to read milestone papers in this field. I think The first paper that proposed the problem is surely an important one. However, I do not know how to find it even after reading several review papers (actually none of them mentions the origin of the field).
Though finding the origin of the field may not sound useful, it is important to me since I have some fundamental doubts about the problem description, etc.
Could anyone help me, thank you in advance.
