Robert Jenssen 撰写论文原文(We introduce kernel entropy component analysis (kernel ECA) as a new method for data transformation and dimensionality reduction. Kernel ECA reveals structure relating to the Renyi entropy of the input space data set, estimated via a kernel matrix using Parzen windowing. This is achieved by projections onto a subset of entropy preserving kernel principal component analysis (kernel PCA) axes)

为了更好地设计通信系统，我们需要对无线环境下收端信号的统计特性进行研究。考虑以下场景：环境中有很多障碍物，发射端至接收端没有视距可达路径。 假设收发端距离很远（500m以上），障碍物数量很大（N>50），并在空间中随机分布。同时假设各路反射信号到达接收端的强度相同（能量E=1），信号载波频率为1GHz，请进行仿真，探索以下问题： （1）接收到的正弦波的相位服从什么分布？ （2）计算接收信号的幅度的均值和方差，并绘制其概率密度函数图。 （3）学习“Rayleigh分布”相关内容，并绘制参数为√NE的Rayleigh分布概率密度函数，计算其期望和方差的理论值。这些理论结果与仿真得到是否一致？ （4）固定障碍物的位置，让接收机分别以速度1m/s和10m/s的速度运动，绘制接收信号的包络随时间变化的曲线。并观察和对比两条曲线，能否有什么发现？(In order to better design the communication system, we need to study the statistical characteristics of the received signal in the wireless environment. Consider the following scenario: There are many obstacles in the environment, and there is no line-of-sight path from the transmitter to the receiver.)

planet示例演示了如何实现一个应用程序，该应用程序结合了使用基于three.js库的Canvas3D呈现和Qt Quick 2D元素。这个例子展示了我们太阳系的八颗行星和太阳。(The Planets example demonstrates how to implement an application that combines the use of three.js library-based Canvas3D rendering with Qt Quick 2D elements. The example shows the eight planets of our Solar System with the Sun.)
