This step essentially just adds metadata to the input columns to ensure Graphext knows that these columns define network links and that they belong to the same set of links (there can be multiple “layers” of links in the same dataset). But it also makes sure all links are valid. E.g. that they don’t refer to rows that don’t exist, that attributes match the number of target rows etc.

​
weight_column
[string, null]
required

Name of the column acting as the weights of the links. Must refer to one of the optional columns passed to the step. If null, an extra output column will be created containing a weight of 1.0 for each link defined in the target column (unless a weight_factor is applied, in which the weights will have the corresponding value, see below).

​
weight_factor
number
default: "1.0"

Multiply link weights by this number. If an input column with weights was identified using weight_column, the values in that column will be multiplied by this factor. If no weights were passed in, the newly added weights will all have this value.
