Methods

toList :: c v k p -> [(k, p)] Source #

Returns a list of index/model pairs.

numModels :: c v k p -> Int Source #

Returns the number of models this classifier can learn.

models :: c v k p -> [p] Source #

Returns the current models of the classifier.

differences :: c v k p -> p -> [(k, v)] Source #

differences c target returns the indices of all nodes in c, paired with the difference between target and the node's model.

classify :: Ord v => c v k p -> p -> k Source #

classify c target returns the index of the node in c whose model best matches the target.

train :: c v k p -> p -> c v k p Source #

train c target returns a modified copy of the classifier c that has partially learned the target.

trainBatch :: c v k p -> [p] -> c v k p Source #

trainBatch c targets returns a modified copy of the classifier c that has partially learned the targets.

classifyAndTrain :: c v k p -> p -> (k, c v k p) Source #

classifyAndTrain c target returns a tuple containing the index of the node in c whose model best matches the input target, and a modified copy of the classifier c that has partially learned the target. Invoking classifyAndTrain c p may be faster than invoking (p classify c, train c p), but they should give identical results.

diffAndTrain :: c v k p -> p -> ([(k, v)], c v k p) Source #

diffAndTrain c target returns a tuple containing: 1. The indices of all nodes in c, paired with the difference between target and the node's model 2. A modified copy of the classifier c that has partially learned the target. Invoking diffAndTrain c p may be faster than invoking (p diff c, train c p), but they should give identical results.

reportAndTrain :: c v k p -> p -> (k, [(k, v)], c v k p) Source #

reportAndTrain c f target returns a tuple containing: 1. The index of the node in c whose model best matches the input target 2. The indices of all nodes in c, paired with the difference between target and the node's model 3. A modified copy of the classifier c that has partially learned the target Invoking diffAndTrain c p may be faster than invoking (p diff c, train c p), but they should give identical results.
