Convolution2D

class Convolution2D[T] extends bigdl.nn.keras.Convolution2D[T] with Net

Applies a 2D convolution over an input image composed of several input planes. You can also use Conv2D as an alias of this layer. The input of this layer should be 4D.

When you use this layer as the first layer of 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

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

Instance Constructors

  1. new Convolution2D(nbFilter: Int, nbRow: Int, nbCol: Int, init: InitializationMethod = com.intel.analytics.bigdl.nn.Xavier, activation: KerasLayer[Tensor[T], Tensor[T], T] = null, borderMode: String = "valid", subsample: Array[Int] = scala.Array.apply(1, 1), dimOrdering: DataFormat = ..., wRegularizer: Regularizer[T] = null, bRegularizer: Regularizer[T] = null, bias: Boolean = true, inputShape: Shape = null)(implicit arg0: ClassTag[T], ev: TensorNumeric[T])

    nbFilter

    Number of convolution filters to use.

    nbRow

    Number of rows in the convolution kernel.

    nbCol

    Number of columns in the convolution kernel.

    init

    Initialization method for the weights of the layer. Default is Xavier. You can also pass in corresponding string representations such as 'glorot_uniform' or 'normal', etc. for simple init methods in the factory method.

    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).

    dimOrdering

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

    wRegularizer

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

    bRegularizer

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

    bias

    Whether to include a bias (i.e. make the layer affine rather than linear). Default is true.

    inputShape

    A Single Shape, does not include the batch dimension.
