Re: Use of GPU & ipynb format

Software has to be developed with GPU usage in mind (and rely on
hardware-specific libraries like NVidia's CUDA) to make this work.
Weka not only predates this, but was also designed to work
cross-platform.

> 2. I would also like to run some of the algorithms within Google Colab. For that I would like access to the ipynb files related to the Weka algorithms. Are these available from a website?

Quite some time ago, I posted on how you can use a Java kernel in
Jupyter to run Weka:

https://waikato.github.io/weka-blog/posts/2019-04-02-jupyter-windows/

There are only two example notebooks (which come with your Weka installation):
https://svn.cms.waikato.ac.nz/svn/weka/trunk/wekaexamples/src/main/notebook/

Alternatively, you could use python-weka-wrapper3 to write more
Python-like code:

Notes on Colab:
