FractionalMaxPool2D

@frozen
public struct FractionalMaxPool2D<Scalar> : ParameterlessLayer where Scalar : TensorFlowFloatingPoint

A fractional max pooling layer for spatial data. Note: FractionalMaxPool does not have an XLA implementation, and thus may have performance implications.

  • Declaration

    public typealias TangentVector = EmptyTangentVector
  • Pooling ratios for each dimension of input of shape (batch, height, width, channels). Currently pooling in only height and width is supported.

    Declaration

    @noDerivative
    public let poolingRatio: (Double, Double, Double, Double)
  • Determines whether pooling sequence is generated by pseudorandom fashion.

    Declaration

    @noDerivative
    public let pseudoRandom: Bool
  • Determines whether values at the boundary of adjacent pooling cells are used by both cells

    Declaration

    @noDerivative
    public let overlapping: Bool
  • Determines whether a fixed pooling region will be used when iterating over a FractionalMaxPool2D node in the computation graph.

    Declaration

    @noDerivative
    public let deterministic: Bool
  • Seed for the random number generator

    Declaration

    @noDerivative
    public let seed: Int64
  • A second seed to avoid seed collision

    Declaration

    @noDerivative
    public let seed2: Int64
  • Initializes a FractionalMaxPool layer with configurable poolingRatio.

    Declaration

    public init(
      poolingRatio: (Double, Double, Double, Double), pseudoRandom: Bool = false,
      overlapping: Bool = false, deterministic: Bool = false, seed: Int64 = 0, seed2: Int64 = 0
    )
  • Returns the output obtained from applying the layer to the given input.

    Declaration

    @differentiable
    public func callAsFunction(_ input: Tensor<Scalar>) -> Tensor<Scalar>

    Parameters

    input

    The input to the layer.

    Return Value

    The output.

  • Creates a fractional max pooling layer.

    Declaration

    public init(
      poolingRatio: (Double, Double), pseudoRandom: Bool = false,
      overlapping: Bool = false, deterministic: Bool = false, seed: Int64 = 0, seed2: Int64 = 0
    )

    Parameters

    poolingRatio

    Pooling ratio for height and width dimensions of input.

    pseudoRandom

    Determines wheter the pooling sequence is generated in a pseudorandom fashion.

    overlapping

    Determines whether values at the boundary of adjacent pooling cells are used by both cells.

    deterministic

    Determines whether a fixed pooling region will be used when iterating over a FractionalMaxPool2D node in the computation graph.

    seed

    A seed for random number generator.

    seed2

    A second seed to avoid seed collision.
