Hi @Wasim04 -
Healpix stands for Hierarchical Equal Area isoLatitude Pixelization of a sphere where partitioning sphere at higher resolutions. So this partition of sphere surface has different size pixels and which is represented as 2D array. So it is better to use Conv1D and Conv2D both are not suitable for healpix image data. Conv1D can create convolution on single dimension data while Conv2D can create convolution on two dimensional data.
JAX library is better option to implement spherical CNNs.
Definitely we can do experiment with Conv1D with healpix data(by projecting MNIST dataset onto HEALPix), but it will not generate good result for large spherical data.
Let me know if you required more details. Thanks..!!
Hi,
Just wondering if there is a way to use Conv1D in a heapix data. That is, it can handle, resolution(nside) and pixel orientation (nested or ring).
Many Thanks Wasim
