1.	Which among the following processes under learning action initiates a change in the action selection policy?(a) Observation of state of the radio system(b) Decision making in reasoning engine(c) Analyses of the outcome of the decision selected by the reasoning engine(d) Modification of knowledge baseThis question was posed to me during an interview for a job.This is a very interesting question from Next Generation Wireless Network in chapter Next Generation Wireless Network of Cognitive Radio
Answer» The correct option is (d) Modification of knowledge BASE The best explanation: The modification of the knowledge base step is generally the final step in a single learning CYCLE. The knowledge base is modified in accordance with the outcome of the actions implemented by the reasoning engine. The EXISTING information in the knowledge base is altered, or the action selection policy is changed. Otherwise, NEW knowledge entries are included in the database.
