Interface CosineDistanceSensitiveFunction

All Superinterfaces:

ToDoubleFunction<float[]>

All Known Implementing Classes:

CosineAverageFunction, DotsFunction

public interface CosineDistanceSensitiveFunction
extends ToDoubleFunction<float[]>

Implementations of this type of function return a value that depends on cosine distance to a target vector and thus makes sense to use with the locality-sensitive hash logic in ALSServingModel.
