%description
An interface for training Fuzzy DBScan with both Fuzzy Core and Fuzzy
Border. Therefore, the package provides a method to initialize and run the
algorithm and a function to predict new data w.t.h. of 'R6'. The package
is build upon the paper "Fuzzy Extensions of the DBScan algorithm" from
Ienco and Bordogna (2018) <doi:10.1007/s00500-016-2435-0>. A predict
function assigns new data according to the same criteria as the algorithm
itself. However, the prediction function freezes the algorithm to preserve
the trained cluster structure and treats each new prediction object
individually.
