2D convolution.

2D convolution.

k_conv2d(x, kernel, strides = c(1, 1), padding = "valid",
  data_format = NULL, dilation_rate = c(1, 1))

Arguments

x

Tensor or variable.
kernel

kernel tensor.
strides

strides
padding

string, "same" or "valid".
data_format

string, "channels_last" or "channels_first". Whether to use Theano or TensorFlow/CNTK data format for inputs/kernels/outputs.
dilation_rate

vector of 2 integers.

Value

A tensor, result of 2D convolution.

Keras Backend

This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
