Elucidation of the more myopic eye in anisometropia: the interplay of laterality, ocular dominance, and anisometropic magnitude

Siyu Jiang, Zheyi Chen, Hua Bi, Ruijing Xia, Ting Shen, Ling Zhou, Jun Jiang, Bin Zhang, Fan Lu

Hao-Hsuan Chang, Hao Song, Yang Yi, Jianzhong Zhang, Haibo He, Lingjia Liu
2018 IEEE Internet of Things Journal  
Furthermore, a special type of recurrent neural network (RNN), called the reservoir computing (RC), is utilized to realize DRL by taking advantage of the underlying temporal correlation of the DSA network  ...  We also show that our scheme outperforms the myopic method which assumes the knowledge of system statistics, and converges faster than the Q-learning method when the number of channels is large.  ...  Furthermore, no centralized controller is assumed in our DSA network to allow fully distributed dynamic spectrum access strategies.  ...
