Add an ICLR'23 paper "Graph Domain Adaptation via Theory-Grounded Spectral Regularization"

[yyou1996]

Thanks for the nice collection effort.

We recently published an ICLR'23 paper Graph Domain Adaptation via Theory-Grounded Spectral Regularization which provides a risk-bound analysis of the graph OOD problem. I believe it is relevant to the interested topic.

Kind regards
