Decision tree machine learning
Decision tree machine learning
I am using the decision tree analysis under machine learning. The model provides a confusion table on the "test set", but there is no mention of other sets used, i.e. a training set. So does this model not use a training set? Where do the predictions come from? And how about the decision tree, is it also created on the current dataset, without utilizing a training set?

Hi Gilmar
Are you using snowCluster module? If you want to get the results of training set, you can use Machine Learning analysis within snowCluster module.
If you want to get the results of training set within decision tree analysis, I will update it soon.

Hi Seol,
Thank you! I mostly want to understand where does the training set the decision tree uses comes from. If it comes from pre designated set, how do we know this set even fits the test set. Or perhaps does it train on a randomized subset of the test set?

Re: Decision tree machine learning
it's a random sub-sample from your own sample
