How to use the multi-dimensional node features

[seekamoon]

Hello, thank you for doing such a good work.

After read the docs(https://opennmt.net/OpenNMT-py/ggnn.html#graph-data-format), I still have a question.

The nodes in the docs have single dimensional features Sentence tokens Feature values Edges --------------- ------------------ ------------------------------------------------------- - - - 0 a a b b <EOT> 0 1 2 3 4 4 2 3 12 <EOT> 0 2 1 3 2 4 , 0 6 1 7 2 5 , 0 4 , 0 5 , , , , 8 0 , 8 1

the first 0 is the feature of the first node -, the second 1 is the feature of the second node -......

I wonder that, if the nodes have multi-dimensional features,

for example, there are two nodes a and b, the feature vector of a is [1,2,3], and the feature vector of b is [4,5,6].

How to set the field of feature values ?

Looking forward to your answer, thank you!

SeekaMoon,

I see there is a typo in the document, but multiple features per node can be provided using ‘,’ to add new dimensions between the tokens. For example, Sentence tokens Feature values Edges

---

• • • 0 a a b b 0 1 2 3 4 4 2 3 12 , 1 10 12 . . . . . . 0 2 1 3 2 4 , 0 6 1 7 2 5 , 0 4 , 0 5 , , , , 8 0 , 8 1 Will result in node 0 having the token label ‘-‘, and features 0 and 1 set; node 1 has label ‘-‘, and features 1 and 10 set; nodes 3 through 8 only have one feature set.

Regards, Steve
