Machine Learning - Output Deep Learning Example Data Extraction Issue

[Gorka Garcia Leiceaga]

Hello,

 

I’m trying to run machine learning using Seismic + Wells – 3D Seismic – Rock Property Prediction. I keep getting error messages (attached pics). Does anyone have an idea about what in my data (seismic and wells) is causing this? I’ve used this OpendTect ML algorthim several times without issues.

 

Any advice on this matter will be greatly appreciated.

Dear Gorka,

This error may originate from a large stepout of the input 3D seismic dataset(s). Is your dataset using the survey inline/crosslone stepout, or larger?

The error may also originate from the target log selection. When selecting the target logs, did you check the value of the 'presence' of the target logs for the interval of interest? Also you may review if the appropriate default logs have been selected for the target mnemonic.

Finally this workflow does not clearly state in v7.0.8 that it should exclusively be used for regressions, thus using a continuous log as target, not a classification type of target log.

In the incoming v7.0.9 the workflow will be disambiguated more clearly between regression and classification.

If this still does not help, you may save your data extraction parameters and send them to our support for further assistance.

Best regards.
