Constructor Detail

Dot

public Dot(SameDiff sameDiff,
           SDVariable i_v,
           SDVariable i_v2,
           int... dimensions)

Dot

public Dot()

Dot

public Dot(INDArray x,
           INDArray y,
           INDArray z,
           int... dimensions)

Full array dot product reduction, optionally along specified dimensions.
See wikipedia for details.

Parameters:

x - input variable.

y - input variable.

z - (optional) place holder for the result. Must have the expected shape.

dimensions - (optional) Dimensions to reduce over. If dimensions are not specified, full array reduction is performed.
