Modifier and Type	Method	Description
`default java.util.Map<org.api4.java.ai.ml.ranking.dyad.dataset.IDyadRankingInstance,java.util.Map<org.api4.java.ai.ml.ranking.dyad.dataset.IDyad,org.api4.java.common.math.IVector>>`	`getPreComputedFeatureTransforms(org.api4.java.ai.ml.ranking.dyad.dataset.IDyadRankingDataset dataset)`	Precomputed the feature transforms for the dataset, this can speed up the runtime as the feature transform will be reduced to O(1) at the cost of O(n).
`int`	`getTransformedVectorLength(int alternativeLength, int instanceLength)`	Get the length of the vector returned by the transform method.
`org.api4.java.common.math.IVector`	`transform(org.api4.java.ai.ml.ranking.dyad.dataset.IDyad dyad)`	Transform the instance of the given dyad (models the skill).
