(cluster clustering-method clustering-method-args target-column)Metamorph transformer, which clusters the data and creates a new column with the cluster id.
clustering-method can be any of:
- :spectral
- :dbscan
- :k-means
- :mec
- :clarans
- :g-means
- :lloyd
- :x-means
- :deterministic-annealing
- :denclue
The clustering-args is a vector with the positional arguments for each cluster function,
as documented here:
https://cljdoc.org/d/generateme/fastmath/2.1.5/api/fastmath.clustering
(but minus the data argument, which will be passed in automatically)
The cluster id of each row gets written to the column in target-column
| metamorph | . |
|---|---|
| Behaviour in mode :fit | Calculates cluster centers of the rows dataset at key :metamorph/data and stores them in ctx under key at :metamorph/id. Adds as wll column in target-column with cluster centers into the dataset. |
| Behaviour in mode :transform | Reads cluster centers from ctx and applies it to data in :metamorph/data |
| Reads keys from ctx | In mode :transform : Reads cluster centers to use from ctx at key in :metamorph/id. |
| Writes keys to ctx | In mode :fit : Stores cluster centers in ctx under key in :metamorph/id. |
