Efficient airport airside ground movement(AAGM)is key to successful operations of urban air *** studies have introduced the use of multi-objective multigraphs(MOMGs)as the conceptual prototype to formulate *** calculation of the shortest path costs is crucial for the algorithmic heuristic search on MOMGs,however,previous work chiefly focused on single-objective simple graphs(SOSGs),treated cost enquires as search problems,and failed to keep a low level of computational time and storage *** paper concentrates on the conceptual prototype MOMG,and investigates its node feature extraction,which lays the foundation for efficient prediction of shortest path *** extraction methods are implemented and compared:a statistics-based method that summarises 22 node physical patterns from graph theory principles,and a learning-based method that employs node embedding technique to encode graph structures into a discriminative vector *** former method can effectively evaluate the node physical patterns and reveals their individual importance for distance prediction,while the latter provides novel practices on processing multigraphs for node embedding algorithms that can merely handle *** regression models are applied to predict the shortest path costs to demonstrate the performance of *** experiments on randomly generated benchmark MOMGs show that(i)the statistics-based method underperforms on characterising small distance values due to severe overestimation;(ii)A subset of essential physical patterns can achieve comparable or slightly better prediction accuracy than that based on a complete set of patterns;and(iii)the learning-based method consistently outperforms the statistics-based method,while maintaining a competitive level of computational complexity.

本文设计了一种以液晶聚合物为介质基板的频率可重构天线,通过调节贴片的位置及尺寸实现天线的阻抗匹配。制备聚合物分散液晶薄膜作为天线的介质,并根据液晶与聚合物的比例分别为7∶3、6∶4、5∶5这3种不同配比以及50μm和100μm两种不同膜的厚度来考察其效果。在电场作用下,液晶微滴会沿着电场方向重新取向排列,通过改变驱动电压的大小,实现天线的频率可重构。经过对比分析得出,液晶含量(质量分数)为70%的聚合物分散液晶薄膜具有最佳的效果,在48 V的驱动电压下实现了62 MHz的频率连续调节,天线的最大增益为3.5 dBi。该基于液晶聚合物的频率可重构贴片天线结构简单、体积小、质量轻,易于集成在各种移动设备中,发展前景广阔。

Understanding the evolution of learning by explicitly modeling learning mechanisms

引用

Current Zoology 2015年第2期61卷 341-349页

作者： michal ARBILLY Department of Psychology University of California Berkeley CA 94720 USA

Models of the evolution of learning often assume that learning leads to the best solution to any task, and disregard the details of the learning and decision-making process along with its potential pitfalls. These models therefore do not explain in- stances in the animal behavior literature in which learning leads to maladaptive behaviors. In recent years a growing number of theoretical studies use explicit models of learning mechanisms, offering a fresh perspective on the issue by revealing the dynam- ics of information acquisition and biases arising from it. These models have pointed out possible learning rules and their adaptive value, and shown that the value of learning may crucially depend on such factors as the layout of the physical environment to be learned, the structure of the payoffs offered by different alternatives, the risk of failure, characteristics of the learner and social interactions. This review considers the merits of explicit modeling in studying the evolution of learning, describes the kinds of results that can only be obtained from this modeling approach, and outlines directions for future research .
