josh.meanings.records.cluster-result
Cluster results are the result of a clustering operationg. They contain a reference to the models centroids, the assignments which generated those centroids, the objective function cost of the clustering, the format that the cluster is saved in, and some configuration details about how the clustering process was run.
Callers who wish to use the cluster result can get access to the centroids with:
(.load-centroids cluster-result)
They can get access to the assignments with:
(.load-assignments-datasets cluster-result)
They can also cluster points with the cluster result with:
(.classify cluster-result x)
Where x is a vector of points in (-> cluster-result :configuration :col-names) order or a map
that contains every col-name as a key.
To save a cluster result to disk
(.save-model cluster-result filename)
To load a cluster result from disk
(load-model filename)

classify-implcljmultimethod
Classifies the specified point using the cluster result.
The input must be either a vector of points in the order specified by the
col-names configuration field, or a map with keys corresponding to the
col-names field.
Returns the index of the centroid that is closest to the point.
Example usage:
(def cluster-result (load-model 'cluster-result.edn')) (def col-names (:col-names (:configuration cluster-result)))
;; classify a point vector (classify cluster-result [5.1 3.5 1.4 0.2])
;; classify a point map (classify cluster-result (zipmap col-names [5.1 3.5 1.4 0.2]))
Classifies the specified point using the cluster result. The input must be either a vector of points in the order specified by the `col-names` configuration field, or a map with keys corresponding to the `col-names` field. Returns the index of the centroid that is closest to the point. Example usage: (def cluster-result (load-model 'cluster-result.edn')) (def col-names (:col-names (:configuration cluster-result))) ;; classify a point vector (classify cluster-result [5.1 3.5 1.4 0.2]) ;; classify a point map (classify cluster-result (zipmap col-names [5.1 3.5 1.4 0.2]))
load-assignments-implclj
(load-assignments-impl this)Loads the assignments dataset sequence from disk.
Loads the assignments dataset sequence from disk.
load-centroids-implclj
(load-centroids-impl this)Loads the centroids dataset sequence from disk.
Loads the centroids dataset sequence from disk.
load-modelclj
(load-model filename)Loads a ClusterResult from the specified filename. Returns the ClusterResult.
Example Usage
To load a model from disk, first you need to save a model. This can be done
with the save-model method:
(.save-model (k-mean 'dataset.csv' 5) 'cluster-result.edn')
Then you can load that model from with the load-model function:
(load-model 'cluster-result.edn')
Loads a `ClusterResult` from the specified `filename`. Returns the `ClusterResult`. __Example Usage__ To load a model from disk, first you need to save a model.

save-model-implclj
(save-model-impl this filename)Saves the cluster result to disk. Returns the filename that the cluster result was saved to.
Example usage:
(save-model cluster-result 'cluster-result.edn')
Saves the cluster result to disk. Returns the filename that the cluster result was saved to. Example usage: (save-model cluster-result 'cluster-result.edn')
