[Walter Roberson]

I would suspect that some of the work involves random numbers. If you use rng() to set the same seed each time before classification then you would probably get the same result each time.

how to do that pls explain while using learner app?

[Walter Roberson]

Call

rng(12345)

then invoke the learner app and train once. Then exit the learner app and repeat the sequence, rng(12345) and go back into the learner app and train once again. I suspect you will get the same results.
