介绍机器学习算法(Machine Learning Algorithms),如EM算法等、最小二乘法、感知机算法、支持向量机算法等。 一、 EM algorithm 简介 EM算法属于贝叶斯学派估计模型参数的方法。贝叶斯学派认为模型存在不可观测的隐变量Z控制着可观测量X,隐变量Z服从不可观测的Q分布,而可观测量分布P(X)是其联合分布P(X,Z)的边缘分布...
A support vector machine (SVM) is a type ofsupervised learningalgorithm used inmachine learningto solve classification andregressiontasks. SVMs are particularly good at solving binary classification problems, which require classifying the elements of adata setinto two groups. SVMs aim to find the best...

from sklearn.neighbors import KNeighborsClassifier knn = KNeighborsClassifier(n_neighbors=3, algorithm="ball_tree") KNN算法分析时也包括训练和预测两个方法。 训练:knn.fit(data, target) 预测:pre = knn.predict(data) 下面这段代码是简单调用KNN分类算法进行预测的例子,代码如下。 # -*- coding: utf-...
前面在写NumPy文章的结尾处也有提到,本来是打算按照《机器学习实战 / Machine Learning in Action》这本书来手撕其中代码的,但由于实际原因,可能需要先手撕SVM了,这个算法感觉还是挺让人头疼,其中内部太复杂了,涉及到的数学公式太多了,也涉及到了许多陌声的名词,如:非线性约束条件下的最优化、KKT条件、拉格朗日对偶、...
If the pathological information contained in human heart sound signals can be accurately classified, it will be very helpful for disease diagnosis and control. Firstly, particle swarm optimization algorithm is used to optimize the traditional support vecto...
