Batchnorm Implemenatation?

[shreyaskamathkm]

Hi,

I was planning to test a few deep networks and was wondering if you have any implementation for the quaternion batch norm? Or any suggestion on how to implement it?
It would be of great help.

Thank you,
Best,

Hi,

I am also interested in this. Did you figure out a method?

[shreyaskamathkm]

@Sahel13 Please take a look at this.

@shreyaskamathkm That implementation of quaternion batchnorm looks quite different from the one introduced here, which requires Cholesky decomposition. Do you know of a reference for that implementation?

Yes this one is different. The original one introduced in the papers simply is too computationally intensive. This implementation originate from a paper by D. Comminiello I believe.

My mistake, the reference is: Quaternion Convolutional Neural Network for
Color Image Classification and Forensics

Thanks for the reference.
