DUPLEX can be adapted to work with undirected graphs through some straightforward adjustments. For undirected graphs, you'll need to create bidirectional edges between connected nodes. However, the phase embedding may not be meaningful here due to the lack of inherent direction. A simpler solution is to omit the phase component, reducing DUPLEX to a GAT specifically for undirected graphs.
