Method Details

similarity

double similarity(SparseVector first,
 SparseVector second)

Calculates the similarity between two SparseVectors.

Parameters:

first - The first SparseVector.

second - The second SparseVector.

Returns:

A value between 0 and 1, where 1 is most similar and 0 is least similar.

deserialize

static Kernel deserialize(org.tribuo.math.protos.KernelProto proto)

Deserializes the kernel from the supplied protobuf.

Parameters:

proto - The protobuf to deserialize.

Returns:

The kernel.
