GA_tsp,TSP问题是指假设有一个旅行商人要拜访n个城市,他必须选择所要走的路径,路径的限制是每个城市只能拜访一次,而且最后要回到原来出发的城市。路径的选择目标是要求得的路径路程为所有路径之中的最小值。使用遗传算法解决att48问题,即48个城...
GA_ The TSP problem refers to the assumption that a traveling merchant wants to visit n cities, and must choose the path they want to take. The path restriction is that each city can only be visited once, and they must eventually return to the original city of departure. The goal of path selection is to require the minimum path distance among all paths. Using genetic algorithms to solve the ATT48 problem, which involves 48 cities (2018-07-28, matlab, 5KB, 下载0次)

贝叶斯方法一篇比较科普的中文介绍可以见pongba的平凡而神奇的贝叶斯方法: http://mindhacks.cn/2008/09/21/the-magical-bayesian-method/，实际实现一个贝叶斯分类器之后再回头看这篇文章，感觉就很不一样。
在模式识别的实际应用中，贝叶斯方法绝非就是post正比于prior*likelihood这个公式这么简单，一般而言我们都会用正态分布拟合likelihood来实现。

文章针对低信噪比下的水下目标定位问题，建立了水下无线传感器阵列网络，该结构包括多个分布式声传感器阵列，它适应于多模态信号处理，既可以利用目标的方位信息，又可以用能量信息。文中提出了用每个阵列接收到的信号能量作为参量完成目标定位并推导了基于能量的最大似然比目标定位方法。数值仿真表明：基于该结构的能量似然函数定位方法，可以有效估计目标的位置。并且比单阵元网络的定位性能和信息传输率上有了较大的提高， 尤其是在低信噪比下情况下，可以大大减小估计的方差。
With novel underwater wireless sensor array network (UWSAN) architecture that consists of multiple distributed arrays of acoustic sensors, maximum likelihood localization based on acoustic energy is proposed for solving the source localization in underwater and low signal to noise ratio. The exactly maximum likelihood (ML) target location estimator is derived. Very impressive simulation results demonstrated the feasibility of such a new approach for underwater wireless sensor network (UWSN).
