常见的算法包括CART(ClassificationAndRegression Tree),ID3,C4.5等。 CART(“Classification and Regression Trees”), C4.5, and CHAID. What do you mean by logistic regression ? 所以,我们这里会从一个很简单的数学模型开始,它叫做SoftmaxRegression 。 So, we start here with a very simple mathematical model called Softmax Regression . EvidencefromaRegression DiscontinuityDesign”的工作论文。 Evidence from a Regression Discontinuity Design'. 注意这里,Logisticregression 是用于分类的,而不是回归。 A note to beginners: Logistic Regression is used for classification, not regression. Multipleregression 和multivariateregression之间的区别是什么? What is the difference between linear and multiple regression ? 这些模型包括logisticregression ,neuralnetworks,和decisiontrees。 Topics include logistic regression , decision tree networks, and neural networks. Multipleregression 和multivariateregression之间的区别是什么? What is the difference between multiple regression and multivariate analysis? 当X只有一个变量时(Linearregressionwithonevariable),称之为simpleregression 。 When there is only one input variable(x), it's called simple linear regression . Multipleregression和multivariateregression 之间的区别是什么? What's the difference between multivariate regression and univariate regression? . 每当涉及到对数据进行分类时,由于其通用性和可解释性,最受欢迎的是LogisticRegression 。 Whenever it comes to classifying data, a common favorite for its versatility and explainability is Logistic Regression . Ridgeregression 通过对系数的大小施加惩罚来解决普通最小二乘法的一些问题。 Ridge regression addresses some of the problems of Ordinary Least Squares by imposing a penalty on the size of coefficients. 式(6.45)被称为Nadaraya-Watson模型或核回归(kernelregression )(Nadaraya,1964;Watson,1964)。 The result(6.45) is known as the Nadaraya-Watson model, or kernel regression (Nadaraya, 1964; Watson, 1964). Gretl(GnuRegression ,EconometricsandTime-seriesLibrary)是一款跨平台的计量分析软件。 The GNU Regression , Econometric and Time-Series Library(gretl) is a software package for econometric analysis. 如果你已经知道MNIST是什么,以及softmax(多项逻辑斯蒂)regression ,那么你可能更喜欢这个快速入门教程。 If you already know what MNIST is, and what softmax(multinomial logistic) regression is, you might prefer this faster paced tutorial. 回归(Regression ):如果需要的输出由一个或多个连续变量构成,那么这样的任务就被称为regression 。 Regression : if the desired output consists of one or more continuous variables, then the task is called regression .第一眼看上去,thepopulationregression line和theleastsquaresline的差异性是细微的令人困惑的。 At first glance, the difference between the population regression line and the least squares line may seem subtle and confusing. Gretl(GnuRegression ,EconometricsandTime-seriesLibrary)是一款跨平台的计量分析软件。 Gretl(Gnu Regression , Econometrics and Time-series Library) is a cross-platform statistical package mainly for econometric analysis. 最终,可以训练出一个有监督学习算法(例如svm,logisticregression 等),得到一个判别函数对y值进行预测。 Finally, we can train a supervised learning algorithm such as an SVM, logistic regression , etc. to obtain a function that makes predictions on the values. 由于Lassoregression 能够产生稀疏模型,所以他可以用来执行特征选择,详情可以参见基于L1的特征选取。 As the Lasso regression yields sparse models, it can thus be used to perform feature selection, as detailed in L1-based feature selection. 式(6.45)被称为Nadaraya-Watson模型或核回归(kernelregression )(Nadaraya,1964;Watson,1964)。 The linear combination of the observations(6) is called the Nadaraya- Watson estimator of the regression function(Nadaraya 1964; Watson 1964). 新的StepwiseRegression 功能还可以帮助我们自动化选择用于预测模型中最重要的变量。 A new batch of Stepwise Regression functionalities can help automate the process of selecting the most important variables to be used in a predictive model. 这些指标详细介绍了Classificationmetrics,Multilabelrankingmetrics,Regression metricsandClusteringmetrics.。 These metrics are detailed in sections on Classification metrics, Multilabel ranking metrics, Regression metrics and Clustering metrics. 对这个问题的早期研究可以追溯到20世纪70年代,有关近期的研究资料,请参阅Koenker,Roger(2005)QuantileRegression ,CambridgeUniversityPress。 Early works on the question date from the late 1970s, but for recent materials see Koenker, Roger(2005) Quantile Regression , Cambridge University Press. 一个全面而易懂的泊松回归简介参见Coxe、West和Aiken的“TheAnalysisofCountData:AGentleIntroductiontoPoissonRegression andItsAlternatives”(2009)。 Coxe, S., West, S.G. and Aiken, L.S.(2009) The Analysis of Count Data: A Gentle Introduction to Poisson Regression and Its Alternatives.
