Instance Constructors

  1. new CosineRandomFeatures(W: DenseMatrix[Double], b: DenseVector[Double])

    W

    A matrix of dimension (# output features) by (# input features)

    b

    a dense vector of dimension (# output features)

    Transformer maps vector x to cos(x * transpose(W) + b). Kernel trick to allow Linear Solver to learn cosine interaction terms of the input
