HML系统在商店偏好决策模型中的应用研究

对混合式机器学习系统（HML）进行了全面系统的介绍，并将其运用于服装消费商店偏好决策行为的研究中。采用上海统计局家庭调查网络，对300户家庭进行抽样分析后发现，服装消费商店偏好的主要影响因素是地区、季节、丈夫和妻子的学历、职业以及子女性别。在此基础上，将HML分析所得的结论与传统的研究方法和结果进行了系统比较：从方法上来看，因为属性变量包含间断变量和连续变量两种，因此传统统计分析要运用两种不同的检测方法对影响因素的相关性作出判断，结果需要经过统计学分析，才能得到结论；而HML分析结果比较直观和简单，便于理解。

Tunnel/predictor display with two-axis control coordination and simplification

A longitudinal-lateral control coordination and simplification concept is considered for a tunnel/predictor display, which presents the command flight path and a specified future aircraft position in a 3-dimensional format to the pilot, for improving flight path control. A basic element of the proposed concept is the generation of common longitudinal-lateral transfer characteristics of the predictor-aircraft system for the crossover frequency region. Control coordination is supported by a dynamics similarity between the longitudinal and the lateral response characteristics of the predictor position in closed-loop pilot control actions. The control coordination and simplification concept is considered to support the pilot in manual flight path control, directed at an enhancement of his control performance and at a reduction of his workload. Results from pilot-in-the-loop simulation experiments support the theoretical findings and show the effectiveness of the proposed predictor concept with control coordination.
