Package org.tribuo.math.util

package org.tribuo.math.util

Provides math related util classes.

There are two interfaces: Merger and VectorNormalizer. Merger is used to combine gradient tensors produced across different examples (i.e., to combine the gradients within a minibatch). VectorNormalizer is used to normalize an array, usually into a probability distribution.
