I've two different datasets A(x1, x2, x3...xn) and B(y1, y2, y3...yn). Each instance in A is linked with an instance in B i.e. only one unique pair exists.
x1 -> y1 x1 -> y2 . . x2 -> y3 x3 -> y3 x4 -> y4 x5 -> y5 predict(xnew -> ynew)?
Also, instances can be duplicate in A as well as B. If I get a new instance in A and a new instance in B, I want to predict whether they both will be linked or not. Please suggest a way to do this. Thanks in advance.
