    Comparison of Different Confidence Intervals under Type-I Censoring Scheme by Ali Algarni, Abdullah M. Almarashi, Debasis Kundu, G. A. Abd-Elmougod, Sayed Abdel-Khalek

    Published 2022-01-01
    “…We proposed the exact confidence interval, for estimators θ^ and lnθ^, asymptotic confidence intervals, confidence interval under likelihood ratio test, and finally, two bootstrap confidence intervals. Under the Bayesian approach, the unknown parameter is estimated and the corresponding credible interval is obtained considering the prior information formulated with the inverted gamma distribution. …”

    Heuristic Sarsa algorithm based on value function transfer by Jianping CHEN, Zhengxia YANG, Quan LIU, Hongjie WU, Yang XU, Qiming FU

    Published 2018-08-01
    “…With the problem of slow convergence for traditional Sarsa algorithm,an improved heuristic Sarsa algorithm based on value function transfer was proposed.The algorithm combined traditional Sarsa algorithm and value function transfer method,and the algorithm introduced bisimulation metric and used it to measure the similarity between new tasks and historical tasks in which those two tasks had the same state space and action space and speed up the algorithm convergence.In addition,combined with heuristic exploration method,the algorithm introduced Bayesian inference and used variational inference to measure information gain.Finally,using the obtained information gain to build intrinsic reward function model as exploring factors,to speed up the convergence of the algorithm.Applying the proposed algorithm to the traditional Grid World problem,and compared with the traditional Sarsa algorithm,the Q-Learning algorithm,and the VFT-Sarsa algorithm,the IGP-Sarsa algorithm with better convergence performance,the experiment results show that the proposed algorithm has faster convergence speed and better convergence stability.…”

    Analysis of Temporal and Spatial Characteristics of Precipitation Series in Weihe River Basin Based on Sample Entropy by MU Jiaxin, SUN Dongyong, RU Ya'nan, WANG Miaomiao, LI Xianwei, LI Ya'nan

    Published 2023-01-01
    “…In a changing environment,the temporal and spatial complexity of precipitation in the Weihe River Basin changes.In this paper,the measured daily precipitation data of 21 meteorological stations in the Weihe River Basin in 59 years from 1960 to 2018 are selected.The static and dynamic evolution characteristics of the complexity of precipitation series in the Weihe River Basin are studied by the moving sample entropy (M-SampEn).The mutation test is carried out by the combination of the moving cut sample entropy (MC-SampEn) and Bayesian analysis.The results show that the complexity of precipitation series in the Weihe River Basin has spatial differences,and the precipitation complexity and intergenerational variation trend in each sub-region are relatively consistent.The precipitation of the upper and middle reaches of Weihe River and Jinghe River Basin mutated in 1995,and that of the lower reaches of Weihe River mutated in 1991 while that of the Beiluo River Basin mutated in 1970 and 2000.…”
