IEEE Conference on Computational Intelligence and Games (CIG)
作者: Synnaeve, Gabriel Bessiere, Pierre
This paper presents a Bayesian model to predict the opening (first strategy) of opponents in real-time strategy (RTS) games. Our model is general enough to be applied to any RTS game with the canonical gameplay of gat... 详细信息

54th Annual IEEE Global Telecommunications Conference (GLOBECOM)
作者: Carvajal, Rodrigo Agueero, Juan C. Godoy, Boris I. Goodwin, Graham C. Univ Newcastle Callaghan NSW 2308 Australia
In this paper we address the joint estimation of phase noise (PHN) and channel impulse response (CIR) in orthogonal frequency division multiplexing (OFDM) systems. We solve the estimation problem utilizing an algorith... 详细信息

Robust EM Continual Reassessment Method in Oncology Dose Finding
收藏 引用
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION 2011年 第495期106卷 818-831页
作者: Yuan, Ying Yin, Guosheng Univ Texas MD Anderson Canc Ctr Dept Biostat Unit 1411 Houston TX 77230 USA Univ Hong Kong Dept Stat & Actuarial Sci Hong Kong Hong Kong Peoples R China
The continual reassessment method (CRM) is a commonly used dose-finding design for phase I clinical trials. Practical applications of this method have been restricted by two limitations: (1) the requirement that the t... 详细信息
