Class MPSMatrixLogSoftMax

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSMatrixLogSoftMax
extends MPSMatrixSoftMax
    MPSMatrixLogSoftMax [@dependency] This depends on Metal.framework. A logarithmic softmax kernel that operates on matrices. A MPSMatrixLogSoftMax object computes: B_ij = ln { Exp { A_ij } / ( Sum_k Exp { A_ik } ) } = A_ij - ln { Sum_k Exp { A_ik } } A and B are matrices which are represented by MPSMatrix objects. This filter computes the same result for MPSMatrices as MPSCNNLogSoftMax filter does for MPSImages by interpreting the columns of the matrix as feature channels, that is the sum runs over column indices. API-Since: 11.0
