AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

I am trying to understand how exactly 3dSVM produces its activation maps. In the documentation for 3dsvm, it mentions that it outputs the sum of the weighted linear support vectors. However, it does not specify how it exactly weights the linear support vectors themselves. In the LaConte paper referenced in the documentation, it was based off the distance from the margin, but the exacting weighting function used was not specified either. Can someone shine some light onto the weighting function that the program uses? Thank you so much!
