Hetero Temporal Data

[DogitoErgoSum]

Is there a data class like TemporalData but for different node types?

[rusty1s]

Currently, TemporalData represents a list of events given by the tuple (src_node_idx, dst_node_idx, timestamp, msg_feature). As such, indices of nodes can represent single types or multiple types.

In particular, our TGN example makes use of a Wikipedia dataset in which nodes represent both users and pages.

Pinging @otaviocx and @Padarn for additional input.

Hi @DogitoErgoSum, thanks for asking!

We are currently in the process to improve the support for temporal graphs (see: #3230). But, the TemporalData class as-is allows you to add custom keys to represent, for instance, the type of the event (or even the node).

Could you please describe a bit more the scenario you are needing hetero temporal data (which architecture, for instance) for us to understand better the requirements?

yes, see #4324 for example. There i show an example of a toy graph where i shall be doing graph classification
