Struct linfa::dataset::CountedTargets
source · [−]pub struct CountedTargets<L: Label, P> { /* private fields */ }Expand description
Targets with precomputed, counted labels
This extends plain targets with pre-counted labels. The label map is useful when, for example, a prior probability is estimated (e.g. in Naive Bayesian implementation) or the samples are weighted inverse to their occurence.
Fields
targets: wrapped target fieldlabels: counted labels with label-count association
