> Is it possible that the final graphs include non-numeric type features, one-way edges and weighted edges?

Hi, we have noticed that in StartingKit, there is a type map reserved for other feature types, e.g., 'cat', 'multi-cat', 'str' and 'timestamp'.
Is it possible that the final graphs include non-numeric type features?

Besides, the StartingKit also supports directed edges and weighted edges.
Is it possible that the final graphs include one-way edges and edges whose weights are unequal to 1?

Hi,

We only consider numeric graph features as specified in the dataset page (https://www.automl.ai/competitions/3#learn_the_details-help).

The provided graphs in all phases are undirected and weighted.

Hi, thank you for the clarification!

I found torch_geometric.data.Data.is_undirected returns False for Public Dataset D.
Could you clarify what you mean by the term "undirected"?

Hi,

We are sincerely sorry for the mistake. Actually both undirected and directed graph datasets are included. You can determine this by the provided api or adjacency matrix.
