Local convolution Module wrapping lax.conv_general_dilated_local.


Applies a (potentially unshared) convolution to the inputs.


inputs – input data with dimensions (*batch_dims, spatial_dims…, features). This is the channels-last convention, i.e. NHWC for a 2d convolution and NDHWC for a 3D convolution. Note: this is different from the input convention used by lax.conv_general_dilated, which puts the spatial dimensions last. Note: If the input has more than 1 batch dimension, all batch dimensions are flattened into a single dimension for the convolution and restored before returning. In some cases directly vmap’ing the layer may yield better performance than this default flattening approach. If the input lacks a batch dimension it will be added for the convolution and removed n return, an allowance made to enable writing single-example code.
