link_rows_by_id

For each row this step iterates over the lists of IDs in one or more target columns, and if a ID exists also in the source column, the corresponding rows will be connected.

Note that while this step allows multiple input columns to be used as link targets, it does not allow for the specification of link weights. See the step link_rows for creating weighted networks. All link weights will be set to 1.0 by default. But see the weight_factor param to specify another constant instead.

​

Usage

The following example shows how the step can be used in a recipe.

​

Inputs & Outputs

The following are the inputs expected by the step and the outputs it produces. These are generally columns (ds.first_name), datasets (ds or ds[["first_name", "last_name"]]) or models (referenced by name e.g. "churn-clf").

​

Configuration

The following parameters can be used to configure the behaviour of the step by including them in a json object as the last “input” to the step, i.e. step(..., {"param": "value", ...}) -> (output).
