    Improving the Minimum Free Energy Principle to the Maximum Information Efficiency Principle by Chenguang Lu

    Published 2025-06-01
    “…However, it has a theoretical flaw, a possibility of being misunderstood, and a limitation (only likelihood functions are used as constraints). This paper first introduces the semantic information G theory and the <i>R</i>(<i>G</i>) function (where <i>R</i> is the minimum mutual information for the given semantic mutual information <i>G</i>). …”

    Indoor Mobile Localization in Mixed Environment with RSS Measurements by Zhengguo Cai, Lin Shang, Dan Gao, Kang Zhao, Yingguan Wang

    Published 2015-05-01
    “…Third, for the Markov transition between LOS and NLOS conditions, an effective unscented Kalman filter (UKF) based interactive multiple model (IMM) is proposed to estimate not only the posterior model probabilities but also a weighted-sum position estimation with the aid of likelihood function. To evaluate the proposed algorithm, a complete hardware and software platform for mobile localization has been constructed. …”
