class SeparableConvolution2D[T] extends bigdl.nn.keras.SeparableConvolution2D[T] with Net

Applies separable convolution operator for 2D inputs. Separable convolutions consist in first performing a depthwise spatial convolution (which acts on each input channel separately) followed by a pointwise convolution which mixes together the resulting output channels. The depthMultiplier argument controls how many output channels are generated per input channel in the depthwise step. You can also use SeparableConv2D as an alias of this layer. The input of this layer should be 4D.

When using this layer as the first layer in a model, you need to provide the argument inputShape (a Single Shape, does not include the batch dimension). e.g. inputShape=Shape(3, 128, 128) for 128x128 RGB pictures.

T

The numeric type of parameter(e.g. weight, bias). Only support float/double now.

    activation

    Activation function to use. Default is null. You can also pass in corresponding string representations such as 'relu' or 'sigmoid', etc. for simple activations in the factory method.

    borderMode

    Either 'valid' or 'same'. Default is 'valid'.

    subsample

    Int array of length 2 corresponding to the step of the convolution in the height and width dimension. Also called strides elsewhere. Default is (1, 1).

    depthMultiplier

    How many output channel to use per input channel for the depthwise convolution step. Integer. Default is 1.

    dimOrdering

    Format of input data. Either DataFormat.NCHW (dimOrdering='th') or DataFormat.NHWC (dimOrdering='tf'). Default is NCHW.

    depthwiseRegularizer

    An instance of Regularizer, (eg. L1 or L2 regularization), applied to the depthwise weights matrices. Default is null.

    pointwiseRegularizer

    An instance of Regularizer, applied to the pointwise weights matrices. Default is null.

    bRegularizer

    An instance of Regularizer, applied to the bias. Default is null.
