Today, I added SOM.
Summary:
For now, I just cluster sonic log, namely DTC and DTS because it is visible. From the scatter plot, we can see that sonic log is better to be divided into 2 or 3 clusters, which are close to prediction performance levels. As a result, the second and third figures are plotted after comparing prediction performance with 4 clustering models. However, some of them are close to prediction results while others are not.
I think that is the best that I can do if only sonic log is included for clustering.
Sonic plot:
Two clusters:
Three clusters:
Tomorrow, I will include some inputs into these models to see if more clusters can be determined and if results could be improved.
