During CPMAI Methodology Phase IV: Model Development, which of the following is not done during this phase?

Algorithm (and initial model) selection takes place in Phase III when baseline approaches are established. Phase IV focuses on building, training, and hyper-parameter tuning of the algorithm already chosen, so algorithm selection is not a Phase IV activity.

B – Model training is explicitly performed in Phase IV (Sec. 4.2). C – Hyper-parameter/model tuning is part of Phase IV (Sec. 4.3). D – The concrete model that will be trained is confirmed in Phase IV after baseline comparison.
