fovi.arch.pretrained_resnet.resnet18(*, weights: ResNet18_Weights | None = None, progress: bool = True, **kwargs: Any) → ResNet

ResNet-18 from Deep Residual Learning for Image Recognition.

Parameters:

• weights (ResNet18_Weights, optional) – The pretrained weights to use. See ResNet18_Weights below for more details, and possible values. By default, no pre-trained weights are used.

• progress (bool, optional) – If True, displays a progress bar of the download to stderr. Default is True.

• **kwargs – parameters passed to the torchvision.models.resnet.ResNet base class. Please refer to the source code for more details about this class.

K-Nearest Neighbors convolution layer for foveated vision.

This layer performs convolution operations over k-nearest neighbors in either visual or cortical space, with learnable filters aligned to spatial kernels.

Parameters:

• bias (bool) – Whether to use bias in convolution.

• ref_frame_side_length (int, optional) – Manual specification of reference frame side length.

• batch_size (int, optional) – Number of output coordinates to process at once for memory efficiency. If None, uses a default based on available memory.

• kernel_backend (str) – Compute backend. auto picks per mode: at inference, cached backends (torch_cached/warp_cached/warp_memory); with gradients enabled, training-capable backends (torch_scatter/torch_compact and registered kernel backends). baseline forces the reference path everywhere.

• _precomputed_knns (tuple, optional) – Internal override containing the precomputed neighbor indices and distances.

__init__(in_channels, out_channels, k, in_coords, out_coords, device='cuda', arch_flag='', sample_cortex=True, bias=False, ref_frame_side_length=None, batch_size=None, kernel_backend='auto', _precomputed_knns=None)

Returns:

Processed features after applying local receptive field

Return type:

torch.Tensor

_apply_local_rf_to_weights()

clear_optimized_cache()

Release derived compact indices and inference-only effective weights.

compute_reference_coords(arch_flag)

Compute reference coordinates for the convolution kernel.

The reference coordinates define the shape of the convolution kernel and can be: - A square grid matching the KNN size - A circular grid matching the KNN size - The first neighborhood of coordinates (foveal reference)

Parameters:

arch_flag (str) – Architecture flag indicating reference coordinate style. Checks for containing: - ‘fovref’: Use first neighborhood as reference (not typically used) - ‘circref’: Use circular reference grid (not typically used) - ‘doubleres’: Double the resolution of reference grid (smoother alignment) - default: Use square reference grid of same total number of elements as the neighborhood

Note

Sets self.ref_coords (torch.Tensor): Reference coordinates tensor of shape [num_ref_coords, 2]

compute_local_rf()

Compute local receptive field weights for each output coordinate.

This method computes the mapping between input KNN coordinates and reference coordinates to determine how each input point contributes to the output. Each KNN neighbor is mapped to its nearest reference grid position (one-hot assignment).

Returns:

Local receptive field weights of shape [n_out, k, n_ref] where:

• n_out is number of output coordinates

• k is number of nearest neighbors

• n_ref is number of reference coordinates

torch.Tensor

load_conv2d_weights(conv2d: Conv2d, strict: bool = False, preserve_kernel_norm: bool = False)

Load weights from a pretrained nn.Conv2d into this layer.

The Conv2d kernel is resampled to match the ref_grid_size if necessary. The H and W dimensions are transposed to align the Conv2d weight convention with the grid_sample coordinate convention used by this layer (row,col) -> (col, row)

Parameters:

• conv2d – A nn.Conv2d layer to load weights from.

• strict – If True, raises error if shapes don’t match. If False, resamples the kernel to match ref_grid_size.

• preserve_kernel_norm – Preserve each output filter’s L2 norm when resampling the spatial kernel.

load_conv3d_weights(conv3d: Conv3d, temporal_strategy='average', strict: bool = False)

load weights from Conv3D with strategy for collapsing over temporal dimension
