reduce-dimensionsclj
(reduce-dimensions algorithm target-dims cnames opts)Metamorph transformer, which reduces the dimensions of a given dataset.
algorithm can be any of:
- :pca-cov
- :pca-cor
- :pca-prob
- :kpca
- :gha
- :random
target-dims is number of dimensions to reduce to.
cnames is a sequence of column names on which the reduction get performed
opts are the options of the algorithm
| metamorph | . |
|---|---|
| Behaviour in mode :fit | Reduces dimensions of the dataset at key :metamorph/data and stores the trained model in ctx under key at :metamorph/id |
| Behaviour in mode :transform | Reads trained reduction model from ctx and applies it to data in :metamorph/data |
| Reads keys from ctx | In mode :transform : Reads trained model to use from ctx at key in :metamorph/id. |
| Writes keys to ctx | In mode :fit : Stores trained model in ctx under key in :metamorph/id. |
