D. Fast Evolution by Eliminating Operations
One of the most challenging aspects of NAS lies in the inefficient
search process, and we address this issue by eliminating
the operations with the least potential. The multi-armed bandit
problem is similar to the NAS problem. The Upper Confidence
Bound (UCB) is used for dealing with the explorationexploitation
dilemma in the multi-armed bandit problem.
