Python算法练习(八)// 算法:线性回归,数据集:fetch_california_housing 一、挖掘目标1)分析、识别影响房屋价格的关键特征;2)预测房屋价格。二、分析方法 经过探索分析发现该案例特征存在①异常值问题②多重共线性问题,通过尝试删除异常值、或不重要特征或有共线性特征来提高R方。本次练习共应用了线性回归、岭回归、...
出现“Process finished with exit code 0”即代表代码运行成功了。 二、简单的统计分析 例如我们在临床搜集到如下数据,两组研究对象,数据构成有分类变量,有数值变量,下面我们来做一个简单数据分析演示。 Python的数据分析主要依赖第三方程序包,以卡方检验为例,我们需要SciPy库中的stats.chi2_contingency函数来执行卡...

算法入门(八)——有“边界感”的支持向量机(SVM) (内附Kaggle实战源码与数据集) 算法源码svm入门数据 机器学习中,支持向量机(SVM)是一种经典的分类算法,它的优势在于高效的性能与良好的泛化能力。简而言之,SVM就像一个能精准“分割”不同类别的高手,它通过找到一个最佳分割线(在高维空间中是超平面),来区分数据...
this topic covers the fundamentals of Support Vector Machines (SVM), a powerful supervised learning algorithm widely used for classification tasks. We'll explore both linear and non-linear SVMs, learn about their underlying concepts, and see practical Python code examples. Let's dive in! 🚀 ...
Code SVM MNIST digit classification in python using scikit-learn The project presents the well-known problem ofMNIST handwritten digit classification. For the purpose of this tutorial, I will useSupport Vector Machine (SVM)the algorithm with raw pixel features. The solution is written in python wit...
LIBSVM是台湾大学林智仁(Lin Chih-Jen)教授等开发设计的,综合使用了包括线性函数,多项式函数,径向基函数,sigmoid函数等在内的不同分类方式,而且支持包括C/C++,python,java,matlab,Octave,R,C#,Perl,Ruby,Weka,Node.js,Scilab,Lisp,,haskell,Cuba,.Net,PHP等等一系列语言(听上去就很强大)。 具体的介绍可以参见林智...
