From the first graph shown on the left, the operation on the constant b can be computed at compile time an optimization known as constant folding. The graph can be further simplified to the one on the right because the constant has a value of zero known as algebraic. Unlike these methods, in this work, we design a learnable metric function for graph structure learning, which will be jointly trained with a taskdependent prediction model.
