代码说明：

说明： kurtogram是一种四阶谱分析工具，用于检测和表征信号中的非平稳性。可用于轴承的故障诊断(The kurtogram is a fourth-order spectral analysis tool elaborated for detecting and characterising nonstationarities in a signal. It relies on the assertion that each type of transient is associated with an optimal (frequency/frequency resolution) dyad (f ; Df) which maximises the kurtosis. The Fast Kurtogram computes the kurtogram over a grid that finely samples the (f ; Df) plane. Its complexity is on the order of N log N. This is the "plain vanilla" code used in paper: J. Antoni, Fast Computation of the Kurtogram for the Detection of Transient Faults, Mechanical Systems and Signal Processing, Volume 21, Issue 1, January 2007, Pages 108-124.)

这是一个经典的形变模型实施,在一个单一的文件用简单的可以理解的代码。功能包括两部分一个简单的弱分类器和一个促进部分: 弱分类器试图找到最佳阈值的数据维数对数据进行分离成两个阶级1和1 要求的进一步提高分类器部分迭代,每一步是变化分类权重miss-classified例子。这造成了一连串的“弱分类器”,表现得像一个“强大分类器” (This a classic AdaBoost implementation, in one single file with easy understandable code. The function consist of two parts a simple weak classifier and a boosting part: The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes-1 and 1 The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier" . )
