[OpendTect_Users] Neural Network Fault Cube Questions

[Nicola Scarselli]

Dear ODT Users,
I have few questions/comments regarding the Neural Network Fault Cube (NNFC) I'm testing at the moment:

1) In order to run NNFC you need to provide a steering cube. Which is the one to use between background and detailed? Which are the parameters suggested for calculating such steering cube?

2) I noticed that my NNFC fails in areas of very steep reflectors - even if these areas are not faulted at all, my NNFC reports very high fault probability there. Is there any attribute I can add/remove/change to the process in order to address this problem?

3) While my NNFC seems to perform well with relatively large fault (length > 300ms), it fails in picking "small" faults (length ≤ 100ms) e.g. polygonal faults. Is this behaviour expected? Is there any recommendation for detecting "small" faults?

Many thanks,
Nicola  

PS Is there any plan for a NNFC webinar?
