Reimplementation of harmonic networks in PyTorch. Original TensorFlow implementation is
here. The reimplementation is not one to one. We reimplement
harmonic convolutions, generalizing them to have per-radius phase offsets. Nonlinearities use a multiplicative
"attentional" model, rather than the C-ReLU proposed by Worrall et al. Additionally, we split the library into two modules:
d2 which contains the standard harmonic network implementation for 2d domains and d3, which is a 3d version, arranged to
ensure equivaraince to rotations along (x, y) axes and allowing arbitrary kernels along z axis. This is useful for volume data
which is anisotropic along one dimension, for instance slice microscopy.
- Clone this repository
- Execute
python setup.py install. In some case this doesn't work properly andpython setup.py developis necessary instead. I am not sure what is the reason for these issues OR - Simply add
git+https://github.com/cpheinrich/harmonic@masterto your requirements.txt file
In examples/mnist2d one can find reimplementation of the RotMNIST experiment from Worrall et al., which requires manually downloading the data using their code.
