回到上一篇文章所提到的 Models 的概念,Models 是Mathematical Data Structures.这类structures,我们称之为机器学习模型,模型会以各种形式表示,如树图、代数方程和概率分布。本篇文章将为大家介绍本系列的第一个模型——Linear Models 线性模型 1.一个栗子 现在我们有一组数据,这组数据是源自Iris鸢尾花数据集的编辑版...

With a clear understanding of our dataset, let’s proceed to construct our linear regression models in Python. Univariate Linear Regression in Python Take‘lstat’ as independent and ‘medv’ as dependent variables or Using ‘lstat’ as the predictor and ‘medv’ as the response: ...
and algorithms similar to what's included in theRevoScaleR packagefor the R language. With revoscalepy, you can write a Python script that creates a compute context, moves data between compute contexts, transforms data, and trains predictive models using popular algorithms such as logistic...

To run that regression model in Python, you can use statsmodels’ formula API. It allows you to express linear models succinctly, using R-style formulas. For example, you can represent the preceding model with the formula 'watch_time ~ C(recommender)'. To estimate the model, just call the...
