We use our proposed method for collaborative filtering in recommendation systems. ...
We use recent results for sampling in graphs to find classes of bandlimited (BL) graph signals that can be reconstructed from their partially observed samples. ...
Based on this information, the system predicts new user-movie ratings. ...

Experimental results on three public recommendation datasets show the superiority of our proposed model against the state-of-the-art group recommendation methods. ...
To further reduce the impact from the cold-start neighbors, we incorporate a self-attention-based meta aggregator to enhance the aggregation ability of each graph convolution step. ...
After the model is trained, for a new arriving occasional group, based on its first-and high-order neighbors, we can predict an accurate embedding for it. ...
