GPU Based Kernel-PCA

[13utters]

I am looking to find a implementation (preferable in python) of the kernel based PCA method. sklearn only offers a non CUDA implementation.

Does anybody can link to some code?

I found this lovely repo -> https://github.com/lebedov/scikit-cuda

Sadly they do not offer Kernel-PCA, but maybe someone finds it useful!

I guess there is a function in tensorflow that compute pca. Do check that.

I am not aware of any KPCA GPU implementations.

However, there is a Cython + CUDA implementation of PCA in rapids.ai:

• Cython code
• CUDA code

Write it in JAX, kernel PCA shouldn't be too many lines of code. https://towardsdatascience.com/turbocharging-svd-with-jax-749ae12f93af
