In this step-by-step tutorial, you'll get started with linear regression in Python. Linear regression is one of the fundamental statistical and machine learning techniques, and Python is a popular choice for machine learning.

有了前面的理论基础,我们现在可以开始使用PyTorch来实现我们的线性回归模型。 5.1 定义模型 首先,我们需要定义我们的模型。在PyTorch中,我们可以通过继承torch.nn.Module类来定义我们的模型,并实现forward方法来定义前向传播。 import torch import torch.nn as nn class LinearRegressionModel(nn.Module): def __init...
Multivariate Linear Regression in Python Here, consider ‘medv’ as the dependent variable and the rest of the attributes as independent variables or using ‘medv’ as the response and all other attributes as predictors: Step 1: Initialize the Boston dataset ...
LinearRegressioncreates the object that represents the model, while.fit()trains, or fits, the model and returns it. With linear regression, fitting the model means determining the best intercept (model.intercept_) and slope (model.coef_) values of the regression line. ...

作为本课程的第一部分,我们将使用线性回归来构建预测模型。线性回归在实践中被广泛使用,即使复杂的预测任务也能自然的适应(Linear regression is widely used in practice and adapts naturally to even complex forecasting tasks.)。 线性回归学习如何从其输入特征中得出加权和。 对于两个特征,我们将有: ...
