torchlogix.layers.LogicConv3d

class torchlogix.layers.LogicConv3d(in_dim, device='cuda', grad_factor=1.0, channels=1, num_kernels=16, tree_depth=None, receptive_field_size=None, implementation=None, connections='random', stride=1, padding=None)

3d convolutional layer with differentiable logic operations.

This layer implements a 3d convolution with differentiable logic operations. It uses a binary tree structure to combine input features using logical operations.

__init__(in_dim, device='cuda', grad_factor=1.0, channels=1, num_kernels=16, tree_depth=None, receptive_field_size=None, implementation=None, connections='random', stride=1, padding=None)

Initialize the 3d logic convolutional layer.

Parameters:

• in_dim (Union[int, tuple[int, int, int]]) – Input dimensions (height, width, depth)

• device (str) – Device to run the layer on

• grad_factor (float) – Gradient factor for the logic operations

• channels (int) – Number of input channels

• num_kernels (int) – Number of output kernels

• tree_depth (int) – Depth of the binary tree

• receptive_field_size (Union[int, tuple[int, int, int]]) – Size of the receptive field

• implementation (str) – Implementation type (“python” or “cuda”)

• connections (str) – Connection type: “random” or “unique”. The latter will overwrite the tree_depth parameter and use a full binary tree of all possible connections within the receptive field.

• stride (int) – Stride of the convolution

• padding (int) – Padding of the convolution
