At the moment the only supported clustering algorithm is Louvain.
Louvain tries to identify the communities in a network by optimizing the modularity of the whole network, that is a
measure of the density of edges inside communities to edges outside communities. The result is a column of cluster IDs (integers),
where the value -1 is reserved for nodes in very small clusters, which are grouped into a “noise” cluster.
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").
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).
The larger the value, the more conservative the clustering.
Cluster with this number of nodes or less will be considered noise.Values must be in the following range:
