Random Fourier Features for PyTorch
Project description
Random Fourier Features Pytorch
Random Fourier Features Pytorch is an implementation of "Fourier Features Let Networks Learn High Frequency Functions in Low Dimensional Domains" by Tancik et al. designed to fit seamlessly into any PyTorch project.
Installation
Use the package manager pip to install the package.
pip install random-fourier-features-pytorch
Usage
See the documentation for more details, but here are a few simple usage examples:
Gaussian Encoding
import torch
import rff
X = torch.randn((256, 256, 2))
encoding = rff.layers.GaussianEncoding(sigma=10.0, input_size=2, encoded_size=256)
Xp = encoding(X)
Basic Encoding
import torch
import rff
X = torch.randn((256, 256, 2))
encoding = rff.layers.BasicEncoding()
Xp = encoding(X)
Positional Encoding
import torch
import rff
X = torch.randn((256, 256, 2))
encoding = rff.layers.PositionalEncoding(sigma=1.0, m=10)
Xp = encoding(X)
