Thank you for your feedback in suing BRAPH 2.

Absolutely, it is possible to extract the learned parameters from a trained neural network model.

Let me to guide you through the process using the “example_NN_CON_WU_Classification_AdjacencyMatrix.m” script as an illustration. After line 69, kindly integrate the following code…[Read more]

The reference manual for braph2 is already included automatically in the software. If you want to know the properties (e.g., P for CompareEnsemble or P1, P2, DIFF for ComparisonEnsemble), you can simply type the following commands in the MATLAB command window:
help CompareEnsemble
and
help ComparisonEnsemble

These commands will show you…[Read more]

Thanks for the further information.
Yes, based on your feedback, it sounds reasonable since, if I understand you correctly, you calculated all the available measures for all 800 subjects.

Should you have any questions, please feel free to write to us.

Best, Yu-Wei

Thanks for the feedback.
May you provide further information: what is the size of the adjacency matrix in your case? Additionally, I wanted to ask two things: (1) how long does it take to run the modified example file, example_FUN_WU.m, on your computer? and (2) have you installed the parallel computing toolbox?

For reference, on my computer…[Read more]

Thanks for the follow-up feedback.
I would like to provide further information based on example_FUN_WU.m about the following
(1) Get individual graph metrics/graph measures.
(2) Get individual correlation matrices/adjacency matrices.

Kindly Follow the steps below:

Thank you for your interest!
Yes, as long as your EEG data can be prepared with the file format in line with the ones in braph2 (e.g. xls, txt), braph2 can perform deep learning analysis in that regard. That also applies to multiplex analysis, one of our latest features with braph2.

About the release of braph2, it will be at the…[Read more]
