Hi @ all,
for a project at university I would like to simulate a changing environment. Basically what I want to do is:
Build a prediction model (e.g. neural network) on a certain data set and simulate two things:
1.) How does the model performance change if new data instances arrive (Performance will go down sooner or later).
2.) How does the model performance change if the model is adapted after a new instance arrives. (Performance should remain constant)
Can I simulate both scenarios in SAS? How can I simulate a stream of new data instances arriving? How do I model the adaption loop mentioned under 2.) in SAS?
Thank you very much in advance for your ideas.
