Abstract Value Members
- abstract def getModels: Seq[Model[PredictionResult[Any]]]
Individual models corresponding to each label
- abstract def getRealLabels: Seq[Boolean]
A boolean sequence indicating which labels are real-valued.
A boolean sequence indicating which labels are real-valued. Its length must be equal to
numLabels. - abstract val numLabels: Int
The number of labels.
The number of labels. Every prediction must have this length.
- abstract def transform(inputs: Seq[Vector[Any]]): MultiTaskModelPredictionResult
Apply the model to a seq of inputs
Apply the model to a seq of inputs
- inputs
to apply the model to
- returns
a PredictionResult which includes, at least, the expected outputs

Compute Shapley feature attributions for a given input in this node's subtree
Compute Shapley feature attributions for a given input in this node's subtree
- input
for which to compute feature attributions.
- omitFeatures
feature indices to omit in computing Shapley values
- returns
matrix of attributions for each feature and output One row per feature, each of length equal to the output dimension. The output dimension is 1 for single-task regression, or equal to the number of classification categories.
