Now, by the algorithm’s selection criterion, we have that since UCB i ;t>UCB i;t, the probability of playing arm iin round tis at most 4 t2. This yields following upper bound on the expected number of pulls of a suboptimal arm i. Lemma 1.2. Let n
WebNov 11, 2024 · We propose a new algorithm, NeuralUCB, which leverages the representation power of deep neural networks and uses a neural network-based random feature mapping to construct an upper confidence bound (UCB) of reward for efficient exploration.
